Answer:

WR = 26

Step-by-step explanation:

Givens

UT = 10

VS = 18

WR = ??

Formula

(WR + UT) / 2 = VS

Solution

Substitute

(WR + 10) /2 = 18

Multiply both sides by 2

(WR + 10/2 * 2 = 18 * 2

Do the multiplication

WR + 10 = 36  

Subtract  10 from both sides

WR + 10 - 10 = 36 - 10

WR = 26

rick earns $500 less than three times as much as jim. if their combined salary is $49,500, how much do they each earn?
zubka84 [21]
All you have to do is set the equation

We call Rick r and Jim j

r+j=49500

r= 3j-500 because rick is 500 when Jim is 3 times his amount.

So all you have to do left is solve it.

Subtitles

3j-500+j=49500

4j=50000
J= 12500 dollars

Subtitles

R= 3(12500)-500= 37000 dollars

In conclusion rick salary is 37000 and Jim is 12500

Hope this helps and if it does please give a brainliest answer :)

Andre is paid $12 per hour at his caddying job and $9.50 per hour working at a local fast food restaurant. He would like to keep
Fynjy0 [20]

The equation that can be used to model this scenario is 12x + 9.5y ≥ 275 and x + y ≤ 25

Let x represents the number of hours Andre works at his caddying job and y represents the number of hours he works at the restaurant.

Since he earn at least $275.00 a week, hence:

12x + 9.5y ≥ 275   (1)

Also, he can work no more than 25 hours, hence:

x + y ≤ 25   (2)

Therefore the equation that can be used to model this scenario is 12x + 9.5y ≥ 275 and x + y ≤ 25
