Answer:
The distance between C and D is 650 miles
Step-by-step explanation:
1.5 over 250
and
3.9 over x
so 3.9 *250 = 975
975/1.5 = 650
making x (the distance between C and D) = 650 miles
Answer:
DF = 57
Step-by-step explanation:
DE + EF = DF
(4x + 10) + (2x - 1) = 9x - 15
Combine like terms on the left side
6x + 9 = 9x - 15
Subtract 6x on both sides
9 = 3x - 15
Add 15 on both sides
24 = 3x
Divide by 3 on both sides
x = 8
DF = 9x - 15 = 9(8) - 15 = 72 - 15 = 57
Checking:
(4(8) + 10) + (2(8) - 1) = 9(8) - 15
(32 + 10) + (16 - 1) = 72 - 15
58 - 1 = 72 - 15
57 = 57
Option C.
No matter how much n decreases, -1 will always be bigger than 9n.
