a. Write an equation that describes all possible numbers of questions that may be on the test.

b. If you have 24 questions worth 4 points apiece, how many questions will be worth 2 points apiece?

a. 2x+4y=100

b. 2 questions

Step-by-step explanation:

For a, you can write out hat equation, which can test if a specific combination will work, and once you have one variable, you can solve another

For b, you can plug 24 into the equation

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
