Answer:
A: 336 km
B: 14 L
Step-by-step explanation:
Use a proportion
210 km / 5 L = x / 8L Cross multiply
8*210 = 5 x
1680 = 5x
x = 1680 / 5
x = 336 km
===============
210 /5 = 588/x Cross multiply
210x = 588 * 5
210x = 2940 Divide by 210
x = 2940/210
x = 14 L
Ox=26+7
15.625 cm^3
17
8.5 / 0.5
2n+7
7 more than twice n would be:
this is because twice n would mean that you'd multiply n by 2, and by 7 more than they mean you would add 7 to that.
