113.04 divided by 3.14 is 36 so 36 is the diameter and to find the radius you just divide 36 by 2 and that is 18.

$5x^{2} \times (x - 4) = 0 \\ x^{2} \times (x - 4) = 0 \\ {x}^{2} = 0 \: x = 0 \\ x - 4 = 0 \: x = 4$

(1.5 + x) / 2 = 2 .... multiply both sides by 2
1.5 + x = 2 * 2
1.5 + x = 4
x = 4 - 1.5
x = 2.5 meters per second

Inessa [10]

Answer:

x=4,y=−2

Step-by-step explanation:

1 Solve for x in -2y+x=8

x=8+2y

2 Substitute x=8+2y into 3y+2x=2

7y+16=2

3 Solve for y in 7y+16=2

y=-2

4 Substitute y=-2 into x=8+2y

x=4

5 Therefore,

x=4

y=−2
