Equation 5x+15=180°

x=33°

Step-by-step explanation:

Angles on a straight line always add up to 180°.

Form an equation:

4x+15+x=180° (Both of the red and blue angles add up to make the straight line).

Collect like terms:

Like terms are terms with the same variables and powers.

4x+x=5x

Put it back into an equation:

5x+15=180°

To find x, you would have to do inverse operations to isolate it.

180-15=165°

5x=165°

165÷5=33° (We divide by 5 because, in algebra, when a number is next to a letter it means times and as we want the inverse we divide).

So, x=33°

Hope this helps :)

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
