Answer:
Jo's age = x = 8 years
Step-by-step explanation:
Let
Jo's age = x
Jo's mother, Anne's age = 4x
In four years time, Anne will be three times as old as Jo.
Jo's age =3( x + 4)
Jo's mother, Anne's age = 4x + 4
How old is Jo?
Equate Jo's age and his mother's age
3(x + 4) = 4x + 4
3x + 12 = 4x + 4
3x - 4x = 4 - 12
-x = - 8
Divide both sides by -1
x = 8
Therefore,
Jo's age = x = 8 years
With the first problem: You always divide from the left, then the rigth. 2+246/6 = 246/6=41 41+2=43
Answer:
the anser to the entire equation is 5
Step-by-step explanation:
after distributing the three, you have to subtract over the 6 to get 3x=15, then divide by 3 to get five
Answer:
The slope of the line = m = 2
Step-by-step explanation:
Given
The points
To determine:
The slope of this graph
Determining the slope between (0, 0) and (1, 2)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [2 - 0] / [1 - 0]
= 2 / 1
Thus, the slope of the line = m = 2
Answer:
x = -1
Step-by-step explanation:
8-2x=-8x+14
8-14=-8x+2x
-6/-6=x
x=-1
