Answer:
x = 1
y = -3/2
Step-by-step explanation:
Step 1: Arrange the equations with like terms in column.
Step 2: You want 1 set of coefficients that are opposites. This problem already has opposites: -2y and +2y.
Step 3: Solve for x.
4x-2y=7
3x+2y=0
--------------
7x = 7
x = 1
Step 4: Substitute the value of x and solve for y.
4(1)-2y=7
4-2y=7
-2y=7-4
-2y=3
y=-3/2

The formula for the lateral area of a cone
is:

Where:
is the radius of the circular base of the cone
As we know its diameter
, its radius is 
is the height of the cone

This is the lateral area of the volcano with the shape of a cone

Answer:
10
Step-by-step explanation:
assuming -16 is inside the radical
rad25-16 +7 subtract the radicals first
rad9+7 square 9
3+7

2ft = 24 inches
3 yds = 6ft
6ft = 72 inches
24 plus 72 = 96
96 inches is your answer
