we know that

Let
y-------> the number of feet that are in x yards
by proportion
<u>Find the value of y</u>

therefore
<u>the answer is the option C</u>

Answer:
11y + 2x + 12
Step-by-step explanation:
put similar numbers together:
1. 7y + 4y = 11y
2. 8 + 4 = 12
3. 2x has no match so it is left alone
Put the numbers back together into a new equation: 11y + 2x + 12
73+42 is correct because it’s addition
<span>x in (-oo:+oo)
(x+20)/2 = 3*x // - 3*x
(x+20)/2-(3*x) = 0
(x+20)/2-3*x = 0
(x+20)/2+(-3*2*x)/2 = 0
x-3*2*x+20 = 0
20-5*x = 0
(20-5*x)/2 = 0
(20-5*x)/2 = 0 // * 2
20-5*x = 0
20-5*x = 0 // - 20
-5*x = -20 // : -5
x = -20/(-5)
x = 4 so x= 4</span>
