59-x=7(11-x)=59 yrs
59-x=77-7x
-x+7x-77-59
6x=18
x=18^6=3

Answer:
The length of y is 8
Step-by-step explanation:
∵ The two chords of the circle intersected at a point
∴ 4 × 12 = 6 × y
∴ y = 48 ÷ 6 = 8
length of 1 bacteria = 300 = 3 *10^2 nanometers
= 3 * 10^2 / 1 * 10^9 m
= 3 * 10^(2-9)
= 3 * 10^-7 m
Answer:
$199.89
Step-by-step explanation:
The bike costs 266.52
The parents are contributing one fourth of this (1/4)
We need to find 1/4th of 266.52
Divide 266.52 by 4 to find out how much Justin's parents are contributing to the bike
The answer is 66.63
Now subtract 66.63 from 266.52
Justin has to pay a total of 199.89
