The answer is A.

You are raising the fraction 1/3 to the value of N then multiplying by 5, having the 5 in front of the sum is still multiplying it by 5.

What is the solution of the system? Use substitution.

4x-y=5

3x-7=2

We need to solve 3x-7=2 for x

Let's start by adding 7 to both sides

3x-7+7=2+7

3x=9

Now just divide both sides by 3 so we can find the value for x

3x/3=9/3

x=3

Now substitute 3 for x in 4x-y=5

4x-y=5

(4)(3)-y=5

-y+12=5

Now add -12

-y=12-12=5-12

-y=-7

Divide both sides by -1 so we can eliminate the negative sign

-y/-1=-7/-1

y=3

The answer is A

You have 50$ to spend at the carnival. First, you must pay $9.20 for an entrance ticket. Each snack costs $4.25, including tax.

asambeis [7]

50 - 9.20 = 40.80 so 40.80/ 4.25 = 9.6 but you can’t buy .6 of a snack so it’s 9

Step-by-step explanation:

average is calculated as

average = $\frac{sum}{count}$

$\frac{sum}{2}$ = 13 ( multiply both sides by 2 )

sum of 2 eldest = 26

Then for the 4 children

average = $\frac{26+2+4}{4}$ = $\frac{32}{4}$ = 8
