In order to answer the question, you need to know what a multiple is. A multiple is a number which can be divided by the original number without a remainder. 
So for example multiples of 5 include: 5, 10, 15, 20, 25, etc... you are basically adding 5 each time. So in this question, you are being asked to list what the multiples of 9 are that are less than 80. You begin by listing the multiples of 9 and stop once you get to 80. 

9,18, 27, 36, 45, 54, 63, 72, 81. You stop here because the last multiple of 9 that you listed is more than 80. So your answer to this question would be: 
9,18, 27, 36, 45, 54, 63, 72.

Is the question asking to see if x = 1, y=-2, and z=2 by solving the three equations?
dybincka [34]

Answer:

2 × 1 +2 +2×2 =8

2+2+4=8

8=8

3×1 +3× -2 + 4×2 =5

3-6+8=5

5=5

1+2 × -2 +2 = -5

1-4+2= -5

-5 = -5

AB:BC is 3:4. Solve for x.
Sphinxa [80]
I got B but I'll show you how I got that answer.

Let's look at AB and BC. AB = 3 and BC = 4.
3/4 = 0.75

On the triangle, AB = 90. And BC = 10x - 20. We need to solve for x and prove that AB/BC = 0.75.

Let's start with Choice A.

10(11) - 20 = 90.

AB = 90
BC = 90.

90/90 = 1. It doesn't equal 0.75. Meaning this answer is wrong.

Now let's look at Choice B.

10(14) - 20 = 120.

AB = 90
BC = 120

90/120 = 0.75

So, 3:4 = 90:120 making Choice B the correct Answer. Let me know if this is correct

Horatio wants to ship a batch of 8 machine parts. The packaging for each part weighs 2 pounds. If each part weighs x pounds, whi
Sever21 [200]
Here is what we know:
8 machine parts
each part = x pouunds
packaging for each part is 2 pounds so 16 pounds for packaging

If y=total weight wiith that information we can form this equation 
y=8x + 16

If each part equals 6 pounds the total shipment will be
y=8x+16
y=8(6) + 16
y= 48 + 16
y=64
