What is the solution to this system:
4x+9y=28
- 4x-y=-28
Answer:
x = 7
y = 0
Step-by-step explanation:
→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:
4x + 9y = 28
-4x - y = -28
__________
8y = 0
y = 0
→Plug in 0 for y, into an equation:
-4x - 0 = -28
-4x = -28
x = 7

what is the solution to : 3(1/2 m - 3) =45
Answer:
[tex]m=36[/tex]
Step-by-step explanation:
We can solve for this equation by isolating [tex]m[/tex] on one side. To do this, we can "reverse" the equation.
[tex]3(\frac{1}{2}m - 3) = 45[/tex]
Let's divide both sides by 3.
[tex]3(\frac{1}{2}m-3)\div3 = 45\div3\\\\\frac{1}{2}m - 3 = 15[/tex]
Add 3 to both sides:
[tex]\frac{1}{2}m - 3 + 3 = 15 + 3\\\\\frac{1}{2}m = 18[/tex]
Multiply both sides by two (since [tex]\frac{1}{2}\cdot2=1[/tex])
[tex]\frac{1}{2}m \cdot 2 = 18 \cdot 2\\\\m = 36[/tex]
Hope this helped!
Answer:
m = 36
Step-by-step explanation:
Step 1:
3 ( 1/2m -3 ) = 45
Step 2:
3/2m - 9 = 45
Step 3:
3/2m = 54
Step 4:
54 ÷ 3/2
Step 5:
54/1 × 2/3
Answer:
m = 36

Express the following vector in the form v=v1i+v2j+v3k. 3u - v if u=(4,7,-3) and v=(2,-7,5).3u - v = ____ i + ____ j + _____ k.(Simplify your answers.)
Answer:
5i+14j-7kStep-by-step explanation:
Given the vectors u = (4,7,-3) and v=(2,-7,5), both vectors are 3-dimensional in nature and can also be rewritten as;
u = 4i+7j-3k and v = 2i-7j+5k
To get 3u-v, we will substitute the given vectors into the expression;
3u-v = 3(4i+7j-3k) - (2i-7j+5k)
open the parenthesis
3u-v = 12i+21j-9k - 2i + 7j - 5k
collect like terms
3u-v = (12i - 2i) + (21j + 7j) (-9k-5k)
3u - v = 10i+28j-14k
To simplify the answer, we will divide through by 2
3u - v = 10i/2+28j/2-14k/2
3u - v = 5i+14j-7k
Hence the simplified form of the expression is 5i+14j-7k

answer this for 18 points btw theres no fractions decimals just normal find th value of x
Answer:
x = 28°Step-by-step explanation:
From the question the figure above is a triangle.
The sum of angles in a triangle add up to 180°
To find the value of x add up all the angles and equate them to 180 to find the value of x
We have
50 + 2x + 3x - 10 = 180
5x + 40 = 180
5x = 180 - 40
5x = 140
Divide both sides by 5
We have the final answer as
x = 28°Hope this helps you

A certain lottery game, 32 numbers are randomly mixed and 7 are selected. A person must pick all 7 numbers to win. Order is not important. What is the probability of winning?
Answer:
Below.
Step-by-step explanation:
The number of combinations of 7 from 32 = 32! / 7! (32-7)!
= 3365856
So it is 1/ 3365856 = 0.000000297
or about 3 in 10,000,000.
Find the least common multiple of 4, 2, and 7
Answer:
28
Step-by-step explanation:
So we know that 2 is already a multiple of 4 so we can just find the least common multiple of 4 and 7. So we can do:
4, 8, 12, 16, 20, 24, 28
7, 14, 21, 28
So the least common multiple between 4, 2, and 7 is 28

PIZZA CRUST Pepe’s Pizza makes 52 pizza crusts the fi rst week and 180 pizza crusts each subsequent week. Dianne’s Delicatessen makes 26 pizza crusts the fi rst week and 90 pizza crusts each subsequent week. In how many weeks will the total number of pizza crusts made by Pepe’s Pizza equal twice the total number of pizza crusts made by Dianne’s Delicatessen?
Answer:
Always.
Step-by-step explanation:
Let's write two equations.
Pepe's Pizza:
They made 52 pizza crusts the first week and 180 crusts each subsequent week. In other words, in x weeks after the first week, their total number of crusts made is modeled by the equation:
[tex]P=52+180x[/tex]
Dianne's Delicatessen:
They made 26 pizza crusts the first week and 90 crusts each subsequent week. So, in x weeks after the first week, their total number of crusts is modeled by:
[tex]D=26+90x[/tex]
And we want to find the number of weeks such that the number of crusts made by Pepe's Pizza is equivalent to twice the number of crusts made by Dianne's Delicatessen. In other words:
[tex]P=2D[/tex]
Substitute P and D for their equations:
[tex]52+180x=2(26+90x)[/tex]
Distribute the right:
[tex]52+180x=52+180x[/tex]
As we can see, the two equations turns out to be the same.
In other words, no matter what week it is (excluding the first week), the amount of crusts made by Pepe's Pizza will always be twice the crusts made by Dianne's Delicatessen.

The sum of two numbers is eleven. One number is thirty-eight less than six times the other. Find the numbers.
Answer:
One of the number is 4 while the other is 7
Step-by-step explanation:
The sum of two numbers is eleven
Let the numbers be x and y
X+ y = 11
One number is thirty-eight less than six times the other
X= 6y-38
X+ y = 11
6y-38 +y= 11
6y+y= 11+38
7y=49
Y= 49/7
Y= 7
X+ y = 11
X+7= 11
X= 11-7
X= 4

It is recommended that pregnant women over eighteen years old get 85 milligrams of vitamin C each day. A doctor is concerned that her pregnant patients are not getting enough vitamin C. So, she collects data on 45 of her patients and finds that the mean vitamin intake of these 45 patients is 81 milligrams per day with a standard deviation of 12 milligrams per day. Based on a level of significance of α = .02, test the hypothesis.H0 : u = 85H1 : u< 85n = 45sample mean = 81σ = 12z based on α = .02 = -2.05 ( if lessthan -2.05 we will reject the null hypothesis)Sample standard deviation = 12/√45 = 1.789z= x-u/σ(o sample) - 81-85/1.789 = -2.236-2.236is less than -2.05 so wereject the H0 : u = 85
Answer:
|Z| = 2.237 < 2.32 at 0.02 level of significance
Null hypothesis is accepted
Recommended that pregnant women not over eighteen years old get 85 milligrams of vitamin C each day
Step-by-step explanation:
Step(i):-
Given sample size 'n' = 45
Mean of the Population 'μ' = 85
Mean of the sample 'x⁻' = 81
Standard deviation of the sample 'σ' = 12 milligrams
Null Hypothesis: H₀:μ=85
Alternative Hypothesis: H₁:μ≠ 85
Step(ii):-
Test statistic
[tex]Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }[/tex]
[tex]Z = \frac{81 -85}{\frac{12}{\sqrt{45} } }[/tex]
Z = -2.237
Level of significance = 0.02
Z₀.₀₂ = 2.32
|Z| = 2.237 < 2.32 at 0.02 level of significance
Conclusion:-
Null hypothesis is accepted
Recommended that pregnant women not over eighteen years old get 85 milligrams of vitamin C each day

Answer:
m∠MON = 24°
Step-by-step explanation:
m∠LOM and m∠MON add up to 90°.
Step 1: Find x
2x + 46 + 3x - 6 = 90
5x + 40 = 90
5x = 50
x = 10
Step 2: Find m∠MON
m∠MON = 3x - 6
m∠MON = 3(10) - 6
m∠MON = 30 - 6
m∠MON = 24°
