4, because it has a higher absolute value than -3
Solve for a by simplifying both sides of the equation, then isolating the variable.
a = 1
Answer:
Option A is correct answer.
Step-by-step explanation:
An equation is having two sides equal. It has an = sign in it.
So, Option A 2y+7 = 9 is an equation as it has = sign in it. So, it is correct option.
All other options do not have = sign in them so, they are not equations.
Volume of first prism = 120 x 12 = 1,440 cubic feet
Volume of second prism = 84 x 6 x 16 = 8,064 cubic feet
The volume of the second prism is more than that of the first.
