Sam wants to save money. the ratio of the amount of money she saved to the amount spend on her last pay check3: 5.if she save $120 on her last paycheck, how much did she spend

200$

Step-by-step explanation:

In this case, we already know the ratio between the savings and the spendings and it's 3:5.

This means that for every 3$ saved, Sam spents 5$.

Then, we only need to do a simply rule of 3, to stablish the amount spended.

If:

120 > 3

X > 5

Solving for X, we have:

120/X = 3/5

X = 120 * 5 / 3

X = 600 / 3

X = 200$

If you want to verify that this calculation is correct, then do the ratio between 120 and 200. If the ratio is 3:5 is correct. Here's the demostration:

120/200 --->simplified by 10: 12/20 >simplified by 4: 3/5

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
