8m + 2q = 18.00
3m + q =. 7.50
8m + 2q = 18.00
-6m - 2q = -15.00
2m = 3.00
m = $1.50 each muffin
3(1.50) + q = 7.50
4.50 + q = 7.50
q= $3.00 for each quarter of milk
14 tens is equal to 140. You get this by multiplying 14 and 10. So the answer to your question is 140.
Answer:
Step-by-step explanation:
Let the number = x
So we are trying to work out what number must be subtract from the numerator and denominator of 5/3 to equal 5/7.
You can write this as:
Then you want to get rid of the fractions so multiply both sides by 3-x
Then multiply both sides by 7
Multiply it out.
35 - 7x = 15 - 5x
Add 7x to both sides:
35 = 15 - 5x + 7x
35 = 15 + 2x
Subtract 15 from both sides
35 - 15 = 2x
20 = 2x
To find x, divide both sides by 2.
x = 10.
