Answer:
joining
Step-by-step explanation:
Divide 42 by 89
now the answer is 0.4719... but to get a percent multiply by 100
the answer is now 47.19... so to round to the nearest tenth your answer is 47.2%
It is 9/16 because 2 1/4 equals 9/4 and 9/4x1/4 equals 9/16

Answer: x = -1 and y = 3
Step-by-step explanation:
Let's start by solving 
for 
Add 5y to both sides
Now we need to divide both sides by 10
That's not the answer for x. We are not done yet :)
Now we need to substitute 
for
Now we need to simply both sides
Now we need to add 25 to both sides
We have the valuee for y! Now we need to find the value for x
To find the value of x, we need to substitute 3 for y in:
Therefore,
The answer is x = -1 and y = 3

The method into creating pink paint is mixing 3 gallons of red paint and 5 gallons of white paint together. This mixture only creates 8 gallons of paint and she needs 16 more. List the factors of 16:
1, 2, 4, 8, and 16
We notice that 8 can be factored out of 16 and becomes:
16 / 8 = 2
If we multiply the sample by 3 (the one already counted plus the two extra), we can discover how much paint is needed. Multiply everything by 3:
3 x 3 = 9
5 x 3 = 15
So in this case, 15 gallons of white paint and 9 gallons of red paint are need and combine for 24 gallons in total.
