Answer:
35 percent
Step-by-step explanation:
To solve this problem we multiply the amount by the percent and add them up to get the total amount times the percent
amount * percent + amount * percent = total amount * percent
4 * .20 + 12 * .40 = (4+12) * x
.8 + 4.8 = 16 x
Combine like terms
5.6 = 16x
Divide by 16
5.6/16 = 16x/16
.35 =x
35 percent
Answer:
x = 5
Step-by-step explanation:
6/18 = x/(20-x)
1/3 = x/(20-x) Multiply both sides by 20-x
(20-x)/3 = x Multiply both sides by 3
20-x = 3x Add x in both sides
20 = 4x Divide both sides by 4
5 = x
Answer:
20
Step-by-step explanation:
Divide 4 by 1/5 in decimal form, 1/5 in decimal form is 0.20. You can get the decimal form by dividing 1 by 5.
So 4/0.20 = 20.
Answer:
(4/3)
Step-by-step explanation:
up four, right three
Answer:
16. D. 180 inches
17. A. 1/20 pound
18. D. (2,6)
19. A. 2/8
20. D. 22
Step-by-step explanation:
16. every 5 feet is 60 inches there is 15 feet because 1 yard=3 feet so 60*3=180
17. when you round it upwards you would have 30/40 and 32/40 so it would be 2/40 and then simply 1/20 so therefore it would be 1/20
18. The cost of milk is 3 so that would be (3,y) then every gallon would be y so (3,1)
19. You know this because when you plug in all the other numbers none of the rest of them work but A so therefore it must be A
20. So first you would multiply 2*2*2*2=8 Then you would divide 172/8=22. So therefore your answer would be 22
