Answer:
1. k + 2 (or other way around, it doesn't matter)
2. PY or P×Y
3. 10 - z
Step-by-step explanation:
1. You are adding here, so you add the two terms together.
2. If we had the amount of rulers and how much they cost, we could multiply to find these. Since we don't, we just leave the two variables to be multiplied.
3. It is asking the difference between two numbers, meaning that you need to subtract. With these types of problems, you always use the first number that appears in the problem to start the expression. For instance, if it had listed z first, then you would have done z - 10.
The area of the whole figure is 92.1
the area of the rectangle is 78
the area of the half circle is 14.13
add them together, you get 92.1
hope this helps :D
Integers are like -4,-3,-2,-1,0,1,2,3,4,5 etc
absolute value tells you how far the number is from 0
so example: |-5|=5=|5|
2 different integers can have the same absolute value
as long as they are negative of each other
like x and -x

The question is incomplete:
17. Tonya's mother is 1.5 times as tall as Tonya was when she was 6. How tall is Tonya's mother? Use the correct number of significant digits.
The image with the information about Tonya's height is attached.
Answer:
68 in.
Step-by-step explanation:
According to the information given, you can write the following expression:
x=1.5y
x=Tonya's mother height
y= Tony's height when she was 6
Also, you know from the table that Tonya's height when she was 6 was 45 in. and you can replace this value in the formula:
x=1.5*45
x=67.5
Because of this, the answer is that Tonya's mother height is 68 in.
