Use the drop-down menus to complete each equation so the statement about its solution is true.

Answer:

Step-by-step explanation:

So,it would be easier to simplify the right equation, so when I say "the right equation", I mean the one I will make right now. It is 8x+9. So the first problem is 8x+9=x+?. Well, if there are no solutions, the slopes have to be the same, and the y-int doesn't matter. So the answer would be + 7x because that will make the x an 8x. If there is one solution, then the slope has to be different. So literally anything but 7x will work. Even constants. If there are infinitely many solutions, then the equations have to be the same. Meaning, you would have to add 7x and 9 to make the left equation the same as the right.

The area of a triangle is 45cm2 and the height is 9 cm. What is the length of the base?

Bess [88]

Formula
A=bh divides by 2

SUBSTITUTE
45=b9 divided by 2

MULTIPLY/DIVIDE

You can either divide by 2 or multiply by 1/2 (gets the same answer)
9 x 1/2 = 4.5

DIVIDE
45 divides by 4.5 = 10

CHECK

A= 10 x 9 divided by 2 or multiply by 1/2 (same answer) = 45

Thus, the answer is 10.
I hope this helped you understand the process!
