Answer:
(21 and 54): 3
(55 and 90): 5
(16 and 30): 2
(42 and 91): 7
(66 and 121): 11
Step-by-step explanation:
Answer
(3,1)
Explanation
(6,2) is the same as (3,1) because the x value and y value are proportional, meaning you multiplied or divided both the x value and y value by the same number.
6 divided by 2 is 3.
2 divided by 2 is 1.
(1,3) doesn't work because the x value and y value are switched.
6 divided by 6 is 1.
2 divided by 6 is not 3.
(8,12) doesn't work because the x value and y value are switched... and it wouldn't work anyways.
6 divided by 3/4 is 8.
2 divided by 3/4 is not 2.
(12,8) doesn't work because the x value and y value aren't proportional.
12 divided by 2 is 6.
8 divided by 2 is not 6.
Therefore only (3,1) could be another ratio to (6,2).
4:1
(grapes);(rasins)
4:1
x:3000
so you then cross multiply
1·x=4·3000
multiply,
x=12000
so the answer is it takes 12000 pounds of grapes to make 3000 pounds of raisins
Answer:

Step-by-step explanation:
Simplify the following:
⇒-9 x + 12 x + 10
Grouping like terms:
⇒(12 x - 9 x) + 10
12 x - 9 x = 3 x:
⇒3 x + 10
