Answer:
m = 9
It means that you are multiplying each of the values inside the parentheses by 2.
Step-by-step explanation:
2(m + 2) = 22
2m + 4 = 22
2m + 4 - 4 = 22 - 4
2m = 18 -Divide both sides by 2
m = 9

Answer:
She sells four loaves of bread.
Step-by-step explanation:
First, convert you fractions to decimals.
13 1/2 = 13.5
2 1/4 -2.25
Next, divide 13.5 by 2.25.
13.5/2.25=6
Two thirds of 6 is 4.
Therefore, the baker sold four loaves of bread.
Answer:
[-6 ± √26]\2
Step-by-step explanation:
y(x) is no such thing.
Now, since this is unfactorable, apply the Quadratic Formula, x = [-b ± √(b² - 4ac)]\2a:
[-12 ± √104]\4
Divide everything by 2 to get the above answer.
