Angle α and β are supplementary angles and when added together equal 180.
Set up an equation:
α + β = 180
β = α +30
Replace β in the first equation, to get:
α + α +30 = 180
Simplify:
2α +30 = 180
Subtract 30 from both sides:
2α = 150
Divide both sides by 2:
α = 150 /2
α = 75 degrees.
Answer:
x = 2
Step-by-step explanation:
To find the x-value that makes the equation true, we would have to solve for x in the equation. To do that, we would have to get the equation in the form x = _. That would be our answer.
4x - 3 = -9 + 7x
Add 9 to both sides to get rid of the -9 on the right side.
4x - 3 + 9 = 7x
Simplify.
4x + 6 = 7x
Subtract 4x from both sides to get rid of the 4x on the left side.
6 = 7x - 4x
Simplify.
6 = 3x
3x = 6
Divide both sides by 3 to get rid of the coefficient of 3 on the left side.
x = 6/3
Simplify.
x = 2
So, the x-value that makes the equation true would be 2.

45.36km/hr.............. ...........
It would take 1 & 4/5
which is an estimate of 2
I got 1 & 4/5 because i multiplied 3/5 & 3
hopefully this helps
