The first time Lori played a game, she scored 100 points. She doubled her previous score each of the next 3 times she played the game. What was Lori's scored the first 4 times she played the game
Answer:
1500 points
Step-by-step explanation:
Given
[tex]Initial\ Score = 100[/tex]
[tex]Rate = 2[/tex]
Required
Determine the total score in first 4 games
This question illustrates a geometry progression and will be solved as follows:
[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]
Where
[tex]a = First\ Term = 100[/tex]
[tex]r = common\ ratio = 2[/tex]
[tex]n = 4[/tex]
[tex]S_4 = \frac{100(2^4 - 1)}{2 - 1}[/tex]
[tex]S_4 = \frac{100(16 - 1)}{1}[/tex]
[tex]S_4 = \frac{100(15)}{1}[/tex]
[tex]S_4 = 1500[/tex]
Hence, the score in first four games total 1500 points

Rearrange x = 7y - 5 to make y the subject.
By rearranging x = 7y - 5 to make y the subject, we get
x + 5 = 7y ( By transposition method )
or, [tex] \huge \purple {\tt {\frac{x + 5}{7} = y}} [/tex]
Answer:[tex] \huge \pink {\tt {y = \frac{x + 5}{7}}} [/tex]
The equation x = 7y - 5 can be rearranged as y = x/7 + 1/7 after making the subject as y.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation is:
x = 7y - 5
To make the subject as y:
x + 5 = 7y
Or
7y = x + 5
y = 1/7[x + 5]
y = x/7 + 1/7
Thus, the equation x = 7y - 5 can be rearranged as y = x/7 + 1/7 after making the subject as y.

If the interior angle of a triangle are (x+1), (2x-2), (3x-5), find the measure of the largest angle?
Answer:
98
Step-by-step explanation:
Mathematically, when we add all the angles of a triangle, we get 180
Thus;
x + 1 + 2x-2+ 3x-5 = 180
6x-6 = 180
6x = 186
x = 186/6
x = 31
so the measure of the biggest angle is 3x -5
= 3(31) + 5 = 93 + 5 = 98
Se corta una manzana en 12 partes, se comen ocho partes. Qué fracción simplificada a su mínima expresión representa la cantidad de manzanas que sobra? A. 1/3 B. 1/ 8 C. 2/ 3 D.1/ 4
Answer:
A. 1/3
Step-by-step explanation:
Dado que:
una manzana se corta en 12 partes y se comen ocho partes.
La fracción de manzanas consumidas = 8/12
= 2/3
La fracción de manzanas que quedan = valor original de la manzana que se corta - la fracción de la manzana que se come
La fracción de manzanas que quedan [tex]=1- \dfrac{8}{12}[/tex]
La fracción de manzanas que quedan [tex]=\dfrac{12-8}{12}[/tex]
La fracción de manzanas que quedan [tex]=\dfrac{4}{12}[/tex]

Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second. -16x^2+129x+119
Answer:
8.90 seconds
Step-by-step explanation:
When the rocket hits the ground, its height ( y ) will be zero. This means we can write the equation as:
0 = -16x²+129x+119So we need to solve that equation:
a = -16b = 129c = 119x = [tex]\frac{-b\frac{+}{-}\sqrt{b^2-4ac} }{2a}[/tex]x₁ = -0.84
x₂ = 8.90
We discard x₁, as it is negative.
So the answer is x₂, 8.90 seconds.
The deli charges $4.50 for a salad weighing 3 pounds and $6.00 for a salad weighing 4 pounds. What EQUATION can be used to represent the cost of the salad, y, for x pounds of salad?
Answer:
y = 1.5x
Step-by-step explanation:
Charge for 3 pounds of salad is $4.50
Charge per pound is thus 4.5/3 = $1.5
Now, we want to write an equation that can be used to represent the cost of salad y for x pounds of salad
Mathematically, that will be;
y = 1.5x

Dr. Mann mixed 9.357 g of chemical A, 12.082 g of chemical B, and 7.502 g of chemical C to make 5 doses of medicine. About how much medicine did he make in grams? Estimate the amount of each chemical by rounding to the nearest tenth of a gram before finding the sum. Show all your thinking.
Answer:
Step-by-step explanation:
.
1) About how much medicine did he make in grams?
Dr. Mann mixed
9.357 g of chemical A,
12.082 g of chemical B,
7.502 g of chemical C
We can determine total amount of medicine that was prepared by Dr. Mann by summing up the chemicals (A,B,C)
=( 9.357grams of A + 12.082grams of B+ 7.502grams of C)
= 28.941 grams in total
The next step is to round up those chemicals value to their nearest tenth as asked by question
Dr. Mann mixed
9.357 g of chemical A= 9.4grams
12.082 g of chemical B,=12.1grams
7.502 g of chemical C =7.5grams
2)Estimate the amount of each chemical by rounding to the nearest tenth of a gram before finding the sum.
Then the sum after rounding up to nearest tenth is
(9.4grams +12.1grams + 7.5grams)
=29 gram

Answer:
5x - 4 = 11
1/2x + 15 = 9
Step-by-step explanation:
I dont exactly know how u would show work.
If it says something is less than a number, then it will be at the back of the equation. So skip that part and u will see it says five times a number. The number is unknown therefore it will a variable (i chose x to be the variable). 5 times x is 5x. Minus the 4 would be 5x - 4. Then it says the equation equals 11. So 5x - 4 = 11.
If it says something is more than a number, it can be on either side of the equation using the commutative property of addition. But if we want to consider it being like subtraction, then it also will be in the back of the equation. A half is one over two (1/2). A half of x is 1/2x. Plus the 15 would be 1/2x + 15. It then states that the equation equals 9. So 1/2x + 15 = 9.
8x - 3(x - 1) = 2x + 6 solve for x and show work
Answer:
x= 1
Step-by-step explanation:
open brackets first
8x - 3x + 3 = 2x + 6
Calculate
5x+3= 2x+6
transpose the like terms
5x-2x= 6-3
calculate
3x= 3
x= 3/3
x= 1
Answer:
x = 3
Step-by-step explanation:
8x - 3(x - 1) = 2x + 6
simplify
8x - 3x + 3 = 2x + 6
add like terms
5x + 3 = 2x + 6
subtract 2x from both sides
3x + 3 = 6
subtract 3 from both sides
3x = 3
divide by 3
x = 3

I WILL MARK BRAINLIEST! I NEED HELP ASAP! Solve for x, y, and a.
Answer:
a = 14, x = 55, y = 60
Step-by-step explanation:
a: Find the number that is between 10 and 18, 10 + 18 = 28 divide by 2 = 14, so a = 14
x: Due to corresponding angles theorem, so x = 55 degrees
y: Straight line is 180 degrees, and as we can see at the left side of the image there's a straight line where only 55 degrees was identified so 180 - 55 = 125 and since x = 55 degrees due to corresponding angles, the angle above y is 120 also due to corresponding angles. A quadrilateral is 360 degrees, so:
125 + 55 + 120 + y = 360
180 + 120 + y = 360
300 + y = 360
y = 60

The Montague family and their neighbors the Capulets attended the school play together. The Montagues bought two adult tickets and three student tickets for $16. The Capulets purchased three adult tickets and two student tickets for $19. How much was each adult and student ticket?
Answer:
The cost for adult tickets be represented by x = $5
The cost for student tickets be y = $2
Step-by-step explanation:
Let the cost for adult tickets be represented by x
the cost for student tickets be y
The Montague family and their neighbors the Capulets attended the school play together. The Montagues bought two adult tickets and three student tickets for $16.
= 2x + 3y = 16... Equation 1
The Capulets purchased three adult tickets and two student tickets for $19.
3x + 2y = 19 ..... Equation 2
How much was each adult and student ticket?
2x + 3y = 16... Equation 1
3x + 2y = 19 ..... Equation 2
We solve using Elimination method
Multiply Equation 1 by 2 and Equation 2 by 3 to eliminate u
4x + 6y = 32..... Equation 3
9x + 6y = 57.... Equation 4
Subtract Equation 4 from 3
-5x = -25
x = 25/5
x = $5
2x + 3y = 16... Equation 1
Since x = $5
2($5) + 3y = 16
10 + 3y = 16
3y = 16 - 10
3y = 6
y = 6/3
y = $2
Therefore:
The cost for adult tickets be represented by x = $5
The cost for student tickets be y = $2
The larger of two numbers is four times the smaller number, and their difference is 18. Find the two numbers.
Answer:
x = 12 , y = 10
Step-by-step explanation:
Let x , y are two numbers.
x > y
1 ) Three times the greater is 18 times their
difference
3x = 18( x - y )
x = 6( x - y )
x = 6x - 6y
6y = 5x
y = 5x/6 ——-( 1 )
2 ) 4 times the smaller is 4 less than twice
the sum of the two
4y + 4 = 2 ( x + y )
2y + 2 = x + y
y = x -2 ——( 2 )
From ( 1 ) and ( 2 ) ,
5x/6 = x -2
( 5x /6 ) - x = -2
( 5x - 6x ) /6 = -2
-x = -12
x = 12
Put x = 12 in equation ( 2 ) , we get
y = 12 - 2
y = 10
Therefore ,
x = 12 , y = 10
