Answer:
A Subtract 87 from 271 and then divide the
difference by 5.75
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
Answer:
M= -3
Step-by-step explanation:
The two points on the graph are (0,4) and(1,1), using the slope formula you get a slope of - 3
X intercept (3/2 , 0)
Y intercept (0, -3)
Answer:
removing 1 x-tile from each side.
Step-by-step explanation:
the question is asking to isolate x and the equation is 2x = x + 3.
to isolate x subtract each side by an x-tile
