You score 86 points on the test, and your friend scores 76 points. a. write a system of linear equations that represents this situation. let x represent the number of points a multiple choice question is worth and y represent the number of points a short response question is worth.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

the correct answers i think are b. and d.

give me brainliest if it is correct!
