Since all three equations are equal, you take 15 x 20, which =300, once again because all of the equations are equal, take 300 and divide it by 5, that will give you your first question mark.{you should have gotten 60.} To find the second one, you are going to apply the same concept, Take 300 and divide it by 6, giving you your second question mark. {you should have gotten 50}...
P.S.: {hope I helped} :)

Answer:

x=5

Step-by-step explanation:

$4x^2-11=89$

add 11 to both sides

$4x^2=100$

Divide 4 on both sides

$x^2=25$

Take the square root of both sides to eliminate the power of two from x

$\sqrt{x^2} =\sqrt{25}$

Simplify

$x=5$

Cant solve this please help me <br><br> 9x-2y=8 <br> Y=2x+1

ki77a [65]

Substitute 2x+1 where y is in the equation:

9x-2(2x+1)=8

Then distribute the -2(2x+1)

9x-4x+2=8

Then combine like terms (the x)

5x+2=8

Then do -2 on both side of the equation sign

5x+2=8
- 2 -2

Then you'd get

5x=6

Then divide 5 on both sides

X= 1.2
