Sumalee won 40 super bouncy balls playing horseshoes at her schools game last night. Later, she gave two to each of her friends. She only has 8 remaining. How many friends does she have?

Answers

Before jumping into doing this problem, it is important to look at all the information's that have been made available in the question. Based on those given conditions the answer to the problem can be easily deduced.
Let us assume the number of friends Sumalee has = x
Then
2x + 8 = 40
2x = 40 -8
2x = 32
x = 32/2
x = 16
So Sumalee has 16 friends. There are numerous ways to get to the answer that is required to be found. This is the easiest and the shortest method. Hope i helped you.

To find this we are first going to SUBTRACT to see how many balls she gave ALL her friends in total:-

40 - 8 = 32

Now we will divide to see how many friends she has.

32 ÷ 2 = 16

Check your work:-

16 × 2 = 32

So, she has 16 Friends.

Hope i helped ya!!!!!!!!!!!!!

There are 22 students on natalies class. new reading books cost $7 each. Natalies class raised $50 washing cars. If there are 2 teachers in nautiliesclass, write and evaluate an expression to show how much more each teacher will have to pay to buy the new book

Answers

22*7 = 50 + 2x (22*7 is the total cost for all students, and the other side needs to match that cost)

evaluate:
22*7 = 50 + 2x
154 = 50 + 2x
104 = 2x
52 = x

Each teacher will have to pay $52.

Since 22 multiplied by 7 is equal to 154$ and the class has already raised 50$ you are still left with 104$ to pay . Sice there are 2 teachers you would divide 104$ by 2 and end up with 52$ .... Each teacher would have to pay 54$

Inverse VariationIf I varies inversely with R and I = 0.15 when R = 50, which equation should be used to show this relationship?   A.I=7.5/R  B.I=7.5R  C.IR=0.75 D.I=R/7.5

If x varies inversely with y and x = 8 when y = 6, find y when x =10.
  A. y=40/3   B.y=5/12    C.y = 7.5  D.y = 4.8

xy = –12. What is the constant of variation for this relationship?
A.–1.2  B. -1/4    C.–0.12  D.–12

V varies inversely with T and V = 18 when T = 3. Which equation shows this relationship?  A.V=6/T  B.V=6T  C.V=54/T  D.V=54T

The capacity of a beaker is 0.1 liter converted to millimeter

Answers

One liter is equal to 1000 milliliters ("milli" comes from Latin, and it's a form of the word thousand: mille. )

so 0.1 liter is 0.1*1000=100

so 0.1 liter is 100 milliliters!
