Tammy made 21, and every 3 she makes Gabby makes 5
divide 21 by 3 ( 21/3 = 7)
no multiply 7 by 5 ( 7 x 5 = 35)
Gabby made 35 serves
Answer:
X= 38
Step-by-step explanation:
A straight line is 180⁰ so we can subtract that by 133⁰ to get the degree on the inside of the triangle which is 47. You then add 47 and 95 to get 142. To get x you subtract 142 from 180
1.Convert 4 3/4 into an improper fraction: 19/4
2.Find a common denominator for 19/4 x 1/9:
36
3. Multiply numerators straight across.
Answer: 19/36
A. 45/100 reduced = 9/20
(divided 45 and 100 by 5 to get 9 and 20)
B. she has finished 27 problems, which is 45% of her homework. In other words
45% of the total problems = 27
if we use X to represent the total amount of problems, then:
45% X = 27
we solved in part A for 45%, which is 9/20, so then:
9/20 x = 27
now all that's left is to solve for x
first multiply both sides by 20
9x = 540
now divide both sides by 9
x = 60
the total amount of problems, or the number of problems she was assigned is 60 problems.
C. If the total amount of problems she had to do was 60, and she has already done 27, then
60 - 27 = the amount of problems she has left
33 = the amount of problems she has left
she has 33 problems left to do.
