$12.21
Step-by-step explanation:
A. x=-5
B. x=5
C. x= -3/2
D. x=3/2
Answer:
x = 5/3
Step-by-step explanation:
Solve for x:
7 x - 15 = -2 x
Add 2 x to both sides:
7 x + 2 x - 15 = 2 x - 2 x
2 x - 2 x = 0:
7 x + 2 x - 15 = 0
7 x + 2 x = 9 x:
9 x - 15 = 0
Add 15 to both sides:
9 x + (15 - 15) = 15
15 - 15 = 0:
9 x = 15
Divide both sides of 9 x = 15 by 9:
(9 x)/9 = 15/9
9/9 = 1:
x = 15/9
The gcd of 15 and 9 is 3, so 15/9 = (3×5)/(3×3) = 3/3×5/3 = 5/3:
Answer: x = 5/3
Answer:

Answer:
The three families will stop at the same place at 1,200 kilometers.
Step-by-step explanation:
1. Let's check all the information given to answer the question:
Family A or 1 stops every 240 kilometers
Family B or 2 stops every 200 kilometers
Family C or 3 stops every 300 kilometers
2. After how many kilometers will they stop at the same place?
Family A or 1 will stop at 240, 480, 720, 960 and 1,200 kilometers.
Family B or 2 will stop at 200, 400, 600, 800. 1,000 and 1,200 kilometers.
Family C or 3 will stop at 300, 600, 900. and 1,200 kilometers.
As we can check the first common stop will be at 1,200 kilometers.
