Your next math test is worth 111 points and contains 32 problems. Each problem is worth either 4 points or 3 points. How many 3

Dafna11 [192]

We call x the 4 points-worth problems and y the 3 points-worth problems

You know that x+y = 32

4x+3y = 111

You know that the difference from the x and y is 32 so write:

x = 32-y

Substitute at x the value of 32-y

4(32-y)+3y = 111

128-4y +3y = 111

-4y+3y = 111-128

-y = -17

y = 17

pochemuha

Answer:

They will need to hire 5 testers.

Step-by-step explanation:

This question can be solved using a simple rule of three.

For each 10 developers, we need 2.5 testers. So how many testers are needed for 20 developers?

10 developers - 2.5 testers

20 developers - x testes

$10x = 20*2.5$

$10x = 50$

$x = \frac{50}{10}$

$x = 5$

They will need to hire 5 testers.
