While you're in the parking lot, you realize that both the lightbulbs and the light switches

Romashka [77]

Cost of Lightbulb = x

cost of switch is x-8

9x + 4(x-8) = 520.50

Use distributive property:

9x + 4x -32 = 520.50

Simplify:

13x -32 = 520.50

Add 32 to both sides:

13x = 552.50

Divide both sides by 13

X = 42.50

A lightbulb costs $42.50

A switch costs 42.50-8 = $34.50

hannah says that 1/8 is not on the number line and cannot be plotted. write a note to hannah about her misunderstanding

ad-work [718]

Answer and explanation :

Hannah said that $\frac{1}{8}$ is not on the number line but she is wrong because $\frac{1}{8}$ can be represented on the number line

When we convert the fraction $\frac{1}{8}$ into decimal then it is equal to 0.125

And 0.125 lies between 0 and 1

If we divide one unit on number line into 10 parts then 0.125 lie between 0.1 and 0.2

And we know that any real number can be represented on number line as 0.125 is a real number so it can be represented on the number line
