The answer is to your question is 1. You must replace t with 12 and then follow the rule of PEMDAS to solve this equation.
Answer:
the second one
Step-by-step explanation:
when we make the fractions have common denominators it would be:
9/12 and 8/12
9/12 is bigger than 8/12, so that inequality is true
Ok, let us use "C" as our variable that will equal the normal price.
(C - $.75) 7 = $2.80
Divide both sides of equation by 7
C - $.75 = $2.80 / 7 Add $.75 to both sides of equation
C = $.40 + $.75
C = $1.15
Answer:
x = 8
Step-by-step explanation:
-4x + 6(6 - 2x) = -7x - 36
-4x + 36 - 12x = -7x - 36
-16x + 36 = -7x - 36
<u> +36 +36</u>
-16x + 72 = -7x
<u>+16x +16x</u>
72 = 9x
divide by 9
<u><em>x = 8</em></u>
