On a final exam, each multiple-choice question is worth 4 points and each word problem is worth 8 points. lorenzo needs at least 50 points on the final to earn a "b" in the class. which inequality represents x, the number of correct multiple-choice questions, and y, the number of correct word problems, he needs to earn a "b"? 4x + 8y < 50 4x + 8y ≤ 50 4x + 8y > 50 4x + 8y ≥ 50

Hence, the inequality that will represent the marks he needs  is:

4x+8y≥50

On a final exam, each multiple-choice question is worth 4 points and each word problem is worth 8 points.

Lorenzo needs at least 50 points on the final to earn a "B" in the class.

Let x be the number of correct multiple-choice questions, and y, the number of correct word problems.

Hence, the inequality that will represent the marks he needs  is:

4x+8y≥50

3

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
