Put the number as x and translate the English into math;
(7x+1)/4=9
Then solve for x
8x+1=36
8x=35
x=4.375 or 4 3/8
Hope this helps.

We can take $1.00 and divide it by 6(the amount of items bought)

Answer:

$-6v^7$

$p^6$

Step-by-step explanation:

$-1v^3 \times -2v^2 \times -3v^2$

$-6v^{3+2+2}$

$-6v^7$

$1/2p^2 \times p^3 \times 2p$

$1/2p^2 \times 1p^3 \times 2p$

$1p^{2+3+1}$

$1p^6$

P = 2(l+w)
120 = 2(35+w)
120/2 = 35+w
60 = 35 + w
60 -35 = w
25 = w

so width = 25

answer is b. 25 meters
