11. Take the logarithm, base X.
a² - ab = 10
Since we are given that b = a - 2, we can substitute for b to get
a² - a(a -2) = 10
a² - a² + 2a = 10 . . . . . eliminate parentheses
a = 5 . . . . . . . . . . . . . . simplify, divide by 2

_____
Check: a² = 5² = 25
ab = 5·3 = 15
X^25/X^15 = X^10 . . . . . the answer works

$1\ pound = 4\ people$

$x = 14\ people$

Cross Multiply

$x * 4 = 1 * 14$

$4x = 14$

Solve for x

$x = 14/4$

$x = 3.5$

Mark traveled 455 miles in 5 hours. At this rate how far could he travel in 7 1/2 hours

marshall27 [118]

Mark could travel 682.5 miles in 7.5 hours.

To solve this you have to find how fast he travels per hour.
455 miles/5 hours=91 mph
91 mph multiplied by 7.5 hours(91 x 7.5)= 682.5
682.5 Miles in 7.5 hours

Hope this helped you! :D
