Answer:y = 160
Step-by-step explanation:
The given equation is expressed as
-80 + y = 80
It is a linear equation with only one variable. The variable is y. The constants on the left hand side of the equation and the right hand side of the equation are - 80 and 80 respectively. To determine the value of the variable, y, we would eliminate the constant on the left hand side of the equation by adding 80 to the left hand side of the equation and the right hand side of the equation. It becomes
-80 + 80 + y = 80 + 80
0 + y = 160
y = 160
Answer: c
Step-by-step explanation:
Answer:
Since there are 2 sides, a front & back, and a top & bottom, you must find the surface area of each of those 3 surfaces and multiply by 2.
Step-by-step explanation:
The formula would be:
Top & Bottom - 5 × 4 (multiply by 2 for top AND bottom)
Front & Back - 5 × 7 (multiply by 2 for front AND back)
Sides - 4 × 7 (multiply by 2 for BOTH sides)

Once you find the 3 surface areas, add the areas all together for the total. (I did not show the answer because that is for you to do on your own.)
Ex. Top & Bottom + Front & Back + Sides
Answer:
f(2) = 1
(1) = 2
(f(2)) = 2
Step-by-step explanation:
f(x) = x
(x) = 2x
f(2) = (2)
f(2) = 1
(1) = 2(1)
(1) = 2
(f(2)) = 2((2))
(f(2)) = 2(1)
(f(2)) = 2
