Answer:

t = 16

Step-by-step explanation:

t/2+7=15

Subtract 7 from each side

t/2 +7-7 = 15-7

t/2 = 8

Multiply each side by 2

t/2*2 = 8*2

t = 16

Q#7: Solve for the variable: 3(x+2) - 9 = 15 - 4(5x - 2) Make sure you round you answer to the nearest whole number.

\blue\textsf{\textbf{\underline{\underline{Question:-}}}}

3(x+2)-9=15-4(5x-2)

\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

  First use the distributive property of both sides:-

3(x+2)-9=15-4(5x-2)

3x+6-9=15-20x+8

Now add 20x on both sides:-

23x+6-9=15+8

On simplification,

23x-3=23

Add 3 to both sides:-

23x=26

Divide by 23 on both sides:-

x=26/23

<h3>Good luck.</h3>

The volume of a box(V) varies directly with its length(l). If a box in the group has a length of 25 inches and k = 15, what is i
Masja [62]
The problem says that V(x) varies directly with its length. This is a proportionality problem. So, V(x) = kl. If you are given a length of 25 inches and a k (proportionality constant) of 15, you are required to find its volume V(x).  

V(x) = kl
V(x) = (15) (25 inches)
<u>V(x) = 375 cubic inches</u>

The volume of the box is 375 cubic inches.
