Atest is worth 75 points. multiple-choice questions are worth 2 points and
short-answer questions are worth 3 points. if the test has 30 questions, how
many multiple-choice questions are there?
o
a. m + s = 5
2m + 3s = 105
o
b. m + s = 75
2m + 3 = 30
o
c. m. s= 30
2m. 3s = 75
o
d. m + s = 30
2m + 3s = 75

D. m+s=30

2m+3s=75

Step-by-step explanation:

let m be the no of multiple choice questions and s be the short questions then there are a total of 30 questions

m+s=30A

there are 2 points for m(multiple choice questions) and 3 points for short questions (s)  and totalling to 75

2m+ 3s=75

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
