Answer:
18 miles
Step-by-step explanation:
<u>Let </u>
- The number of miles = x .
<u>According</u><u> to</u><u> Question</u><u> </u><u>,</u>
- 100 + 0.5(x) = 40 + 0.8(x)
- 100 + 0.5x = 40+ 0.8x
- 100 - 40 = 0.8x - 0.5x
- 60 = 0.3x
- x = 60/3 * 10
- x = 18
Answer:
Step-by-step explanation:
4 cups of J for every 7 cups of soda 4:7
21 cups of soda will take 12 cups of J
If you take the 7 and multiply by 3 you get the 21.
So you will need to multiply the 4 by the 3 to get the 12. You need to keep everything in proportion.
4:7 same as 12:21

Answer:
AB = 13
BC = 9
Step-by-step explanation:
AC = AB + BC
AC = (4x - 3) + (2x + 1)
AC = 6x - 2
If AC = 22.....,
then we equate the statements..so that we can obtain the value of x
; 6x - 2 = 22
; 6x = 24.....hence giving...x = 4
Then back to the question...if x = 4
then..,
;AB = 4(4) - 3
;AB = 13
;BC = 2(4) + 1
;BC = 9
