Answer:
Simplifying
6x + -3 = 21 + -2x
Reorder the terms:
-3 + 6x = 21 + -2x
Solving
-3 + 6x = 21 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
-3 + 6x + 2x = 21 + -2x + 2x
Combine like terms: 6x + 2x = 8x
-3 + 8x = 21 + -2x + 2x
Combine like terms: -2x + 2x = 0
-3 + 8x = 21 + 0
-3 + 8x = 21
Add '3' to each side of the equation.
-3 + 3 + 8x = 21 + 3
Combine like terms: -3 + 3 = 0
0 + 8x = 21 + 3
8x = 21 + 3
Combine like terms: 21 + 3 = 24
8x = 24
Divide each side by '8'.
x = 3
Simplifying
x = 3
Step-by-step explanation:
Answer:
as a ratio 21:7
if its not as a ratio then it would be Amanda gets 21 and Busi gets 7
This is the application of ratio and proportion. You have to
formulate the proportion for this problem:
50 deliveries : 5 days = 400 deliveries : x days
The inner numbers when multiplies should equal the product
of the outer numbers.
400 (5) = 50x
50x = 2,000
x = 40
Therefore, it would take 40 days for the trucking company to
deliver 400 deliveries.
