Rachel took a total of 21 quizzes over the course of 3 weeks. After attending 10 weeks of school this quarter, how many quizzes will Rachel have taken in total? Solve using unit rates.

70

Step-by-step explanation:

If 3 weeks, 21 quizzes was done

If 10 week, how many quizzes was done

So technically this is what the question is about

So let's count in 1 week, how many quizzes were done, to do that, just divide

21/3

= 7

Therefore we can take it as, in one week, 7 quizzes will be done

Therefore in 10 weeks

= 7 x 10

= 70

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
