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
Answer:
23/21
Step-by-step explanation:
The slope is computed from ...
m = (y2 -y1)/(x2 -x1)
For the given points, the slope is ...
m = (26 -3)/(18-(-3)) = 23/21
The slope of the trend line is 23/21.
Answer:
12
Step-by-step explanation:
sum of all angles of triangle =180
3x-12+2x+11x=180
