help pwease pls i cant put a pic but it says make a expressions thats equivalent to 5(6+y)=_+_
Answer:
30 + 5y
Step-by-step explanation:
Distribute the 5
5*6 = 30
5*y = 5y
and add
Answer:
[tex]5y+30[/tex]
Step-by-step explanation:
This equation on the left wants us to use the distributive property. That means we can distribute 5 to the 6, and the y in the equation. So, we will multiply.
[tex]5(6)=30\\5(y)=5y[/tex]
And, it wants us to add the two, so therefore it would be [tex]5y+30[/tex]

Mrs. Thomas car averages 23 miles per gallon. How many gallons of gasoline will she need in order to make the round trip ? If the price of gasoline is $2.13 per gallon, what is the cost of the gasoline for the entire trip?
In addition to paying for the gasoline, Mrs. Thomas must also pay $13.92 fo her lunch and $32.98 for her dinner. What is the total amount of her meal expenses?
a. What is the total amount of her gasoline and meal expenses?
b. What operation did you use to figure it out ?
Answer:
a. $70.43
b. 23.43 + 13.92 + 32.98 = t (UNSURE)
Step-by-step explanation:
Since Mrs. Thomas is driving 231 miles using 23 miles per gallon, let's start by dividing 231 by 23
[tex]\frac{231}{23} = 10.043....[/tex]
We need to round 10.043... to 11 because you can't get part of a gallon.
Now, we need to multiply 2.13 by 11 to get the total amount of money for gasoline.
[tex]11 * 2.13 = 23.43[/tex]$
We also have the aditional meal expenses, which are $13.92 and $32.98.
We can use an equation to solve. Our total amount will be represented by t.
[tex]23.43 + 13.92 + 32.98 = t[/tex]
[tex]t = 70.43[/tex]
Hope this helps! Part b seems a bit confusing. I'll fix my answer if you could clarify, like if I do "communative property" or write equation. :))
Dilate the rectangle below by a scale factor of 2. If the current side lengths are 15
and 8, what are the side lengths on the new dilated rectangle?
In your answer, give the new side lengths for the dilated image and explain how you
calculated them.
A
15 cm
B
8 cm
C
D
Answer:
AB and CD would be 30
AC and BD would be 16
Step-by-step explanation:
The scale factor is what you multiply the sides by. Dilate means wider or larger so you multiply each side by the scale factor of 2 to get the higher scaled rectangle.

The function f(t) = 880(0.1) represents the change in a quantity over t
hours. What does the constant 0.1 reveal about the rate of change of the
quantity?
Answer:
Step-by-step explanation:
the function is decaying exponentially at a rate of 90%
0.1-1=0.9 x100 =90 and it’s decaying because r (0.1) is less than one

Answer:
f(x)=2x−5 if x≤−3
Since the value of x is -3, the first function will be the correct option.
Step-by-step explanation:
The given function is -
f(x)=2x−5 if x≤−3
f(x)=−3x+4 if x>−3
Now we have to evaluate f(-3).
Since we have to calculate the value of f at x = -3, we have to choose the first function.
That is f(x) = 2x - 5.
Hence,
f(−3)=2∗(−3)−5=−6−5=−11
Therefore we have the value
f(−3)=−11
Since the domain of the function is divided into two parts, we have to choose any one function for a given value of x,
For values of x less than or equal to -3, we will use the first function. That is,
f(x)=2x−5 for all x∈(−∞,−3]
And for values of x greater than -3, we will use the second function. That means,
f(x)=−3x+4 for all x∈(−3,∞)
How do I remove the 1 on the numerator when solving for x
1/x = 5
Answer:
x = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
[tex]\frac{1}{x}[/tex] = 5 ( multiply both sides by x to clear the fraction )
1 = 5x ( divide both sides by 5 )
[tex]\frac{1}{5}[/tex] = x
Evaluate the function
Answer:
-101
Step-by-step explanation:
Put 9 where x is, and do the arithmetic.
f(x) = -x² -20
f(9) = -9² -20 = -81 -20
f(9) = -101
Linear or nonlinear?
A father is twice as old as his son and the sum of their ages is 75. How old is the
father?
Answer: 50
Let's first of all assume the son's age as x.
So,
Father's age will be 2x i.e. twice as old as the son
Given that,
Sum of their ages = 75 years
So,
x + 2x = 75
3x = 75
x = 75/3
x = 25
Hence,
Son's age = x = 25 years
Father's age = 2x = 2 * 25 = 50 years
why do we have to learn math
Math is not present only in exercises of school, but it is present in day-to-day life of society. For example, math can be used to:
• pay your bills;
• go to supermarket;
• go to restaurant;
• make a cake or a favorite dish ;
• play music;
• read time in a watch;
• take a medication;
• write a code for an app mobile.
A great advantage is that numbers are universal, thus the number are the same independent of your location.

It is the science that relates everyday practices and nature to human reasoning and numerical logic.

first box = 240second box = n+pExplanation:
For the first box, we add the two values 90 and 150 to get 240.
The same goes for the second box as well, except we cannot combine n and p together. We leave it as n+p. If we knew what numbers replaced n and p, then we could simplify further.

Hope Helps~In the rectangle below, AC has a length of 28 units. What is the length of DE?
D
A
LD
O A. 56 units
O B. 21 units
O C. 28 units
D. 14 units
Answer:
D. 14 units
Step-by-step explanation:
it is a rectangle.
that means both diagonals are equally long.
E is in the middle of of diagonals.
so, since the whole diagonal (AC = DB) is 28 units long, one half of such a diagonal (AE = EC = DE = EB) is then
28/2 = 14 units long.
What would you make the size of one of the sides of a right triangle if its other side is 12cm and the hypotenuse is 20cm?
A triangle has the three sides of 2cm, 6cm, and
[tex] \sqrt[2]{10} cm[/tex]
is it a right triangle-yes or no
Step-by-step explanation:
1. 400-144 = 256
unknown side = 16 cm
2.
√10 = 3.16
the biggest side is hypotenuse. assuming 6cm is the hypotenuse.
4+10= 14, which is different From hypotenuse. so it's not a triangle

Find the 88th term of the arithmetic sequence 4, -1, -6, ...4,−1,−6,...
Answer:
88th term = -431
to solve, keep subtracting 5
Answer:
a₈₈ = - 431
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 4 and d = a₂ - a₁ = - 1 - 4 = - 5 , then
a₈₈ = 4 + (87 × - 5) = 4 + (- 435) = 4 - 435 = - 431

Is 690,269 divisible by 9? Yes or No?
False, But I do not know why, I do not know whether it is false or not, but I think it is false.
Answer:
False.
Step-by-step explanation:
It is false because when dividing an odd number by an odd number, it usually isn't divisible. In this case, 690,269. Is an odd number, because the last number, 9, is odd, which makes the whole thing odd. So, odd divided by odd never turns out well. (By the way the answer is 76,696.5555556).
