<h3>Answer: Choice A.  3/4</h3>

Work Shown:

x = number of weeks

y = number of tests

slope = rise/run

slope = (change in y)/(change in x)

slope = 27/36

slope = (9*3)/(9*4)

slope = 3/4

A slope of 3/4 means that there are 3 tests for every 4 weeks.

What two numbers add up to 18 and multiply to 80
mestny [16]

Answer:

8 and 10

Step-by-step explanation:

First, let's look at the factors of 80.

1 • 80 = 80

2 • 40 = 80

4 • 20 = 80

5 • 16 = 80

8 • 10 = 80

Look at each pair and evaluate their sum.

1 • 80 = 80

  • 1 + 80 = 81

2 • 40 = 80

  • 2 + 40 = 42

4 • 20 = 80

  • 4 + 20 = 24

5 • 16 = 80

  • 5 + 16 = 21

8 • 10 = 80

  • 8 + 10 = 18

Our last pairing multiplies to 80 and adds up to 18. Therefore, your answer is 8 & 10.

Hope this helps!

30 students chose the planetarium.

40 students chose the farm.

The students can't vote for more than one place, so you just add all the numbers together.
