Answer:
3/88 is your answer
Step-by-step explanation:
Given
Rob is twice Joshua's age
Nick is 5 years older than Joshua.
sum of all their ages is 45.
Find the age of nick.
To proof
As given
Rob is twice Joshua's age
let Joshua's age = x
than Rob age = 2x
Nick is 5 years older than Joshua.
Nick age = 5 + x
sum of all their ages is 45
than the equation becomes
Joshua's age + Rob age + Nick age = 45
put the value
x + 2x + 5 + x = 45
4x = 40
x = 10
Joshua's age = 10 year
than Rob age = 20 year
Nick age = 5 + 10
= 15year
Hence proved

A straight angle is 180 degrees in a right angle is 90 degrees
Answer:
y=-3x-13
Step-by-step explanation:
Plug in the -2 and -4 for the y and x. The slope is the same
1) -4 = -3 (-3)+b
2) -4=9+b
3) -4-9=b
4) -13=b
The equation is y=-3x-13
