That’s not enough information to say how long he could do it. He could go slower or faster than her but by how much if so. So it’s not enough info.
Just divide 70 by 2 and you get 35
To see how they are related, let us solve the two equations.
FIRST EQUATION
SECOND EQUATION
Hence the solutions to the two equations are ADDITIVE INVERSE of each other.
Interval notation
(-infinity sign, 1)

Answer:
x=75
Step-by-step explanation:
Hey There!
If you didn't know the exterior angle of a triangle is equal to the sum of the opposite interior angles of a triangle
So essentially what I'm saying is that
2x-5=70+x
step 1 add 5 to each side
-5+5 cancels out
70+5=75
now we have
2x=70+x
step 2 subtract x from each side
x-x cancels out
2x-x=x
we're left with
x=75
