Amath test is worth 100 points and has 30 problems. each problem is worth either 3 points or 4 points. how many 4- point problems are there?

Ten

Step-by-step explanation:

The harder part is to make an equation out of the text.

Let x be the number of 3 point questions.

In this case the nu,ber of 4 point questions is (30-x)

They all add up to 100 points.

3x + 4(30-x) =100

Solve for x

x=20

There are 20 three point questions

30-20=10 There are ten four point questions.

Lets check.  20*3 + 10*4 = 60+40=100

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
