joyce correctly answered 15 out of 20 questions on her french test. what percent did she answer correctly?

75%

Step-by-step explanation:

If Joyce got 15 questions out of 20 right, that would mean she got a 15/20.

To get a percent from a fraction, you divide the numerator by the denominator and multiply that by 100.

So 15 / 20 =.75

.75 x 100 = 75%

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.

i believe a. 12x≥120 is the answer
