The volume of a rectangular prism can be given by the form
V= b*h*w

you know Volume, base, and height but you dont know width

so divide b and h to both sides
\frac{V}{b*h} = w
and you cna solve for width

now for 6.
dividing by a number is the same as multiplying by its reciprocal

n \div 6  = n * \frac{1}{6}

PLS HELP WITH BOTH ASAP WILL GIVE BRAINLIEST
weeeeeb [17]

Answer:

13) 25 and 17

14) cupcakes = $5

brownies = $3

Step-by-step explanation:

13)  you can set this up as equations

so x + y = 42

x-y = 8

solve simultaneously by subtracting from each other

2y = 34

y= 17

if y = 17

42 - 17 = 25 = x

14) set up as equations again

Ben    7c + 10b = 65

franklin   7c +7b = 56

subtract from eachother

3b = 9

b = $3

7c + 10(3) = 65

7c = 35

c = $5
