Answer:
8
Step-by-step explanation:
Number = 2x
Therefore, 2x + 8 = 8(x - 5)
2x + 8 = 8x - 40
6x = 48
<u>x</u><u> </u><u>=</u><u> </u><u>8</u>
No it will not change it will be 250% then it will decrease 100% down again back to 150%
After 300 miles.
35+0.1x= 25+0.15x
<u> -0.1x -.01x</u> (0.1- 0.1 crosses out)
35= 25+0.15x
<u> -25 -25 </u> (25- 25 crosses out)
15= 0.15x
15/0.15= 0.15x/0.15 (crosses out)
300= x
16*18 is 288
