6 0

Answer: 14 and -4

Step-by-step explanation:

From the first statement: Let the first number be x and the second number be y , then x + 2y = 6.

From the second statement: 2x + y = 24

Combining the two equations , we have

x + 2y = 6 ......................... equation 1

2x + y = 24 ........................ equation 2

Solving simultaneously

x = 14 , y = -4

Someone please help me with #28 and #30 I got myself super confused.

bogdanovich [222]

Question 28:

$S-2\pi r^2=2\pi rh$ Subtract $2\pi r^2$ on both sides

$\frac{S-2\pi r^2}{2\pi r} =h$ Divide $2\pi r$ on both sides

*(Answer)*= $\frac{S-2\pi r^2}{2\pi r} =h$

Question 30:

$a*t=v_{1}+v_{0}$ Multiply $t$ on both sides

$a*t+v_{0} =v_{1}$ Subtract $v_{0}$ on both sides

*(Answer)*= $a*t+v_{0} =v_{1}$

Hope This Helps
