Steps to solve:
5(x + 1) = 20
~Distributive property
5x + 5 = 20
~Subtract 5 to both sides
5x + 5 - 5 = 20 - 5
~Simplify
5x = 15
~Divide 5 to both sides
5x/5 = 15/5
~Simplify
x = 3
Best of Luck!
Answer:
2x + 3(8 - 3x) = 3
x = 3
y = -1
Step-by-step explanation:
2x + 3y = 3
y = 8 – 3x
2x + 3(8 - 3x) = 3
2x + 24 - 9x = 3
7x = 21
x = 3
y = 8 - 3(3)
y = -1
Answer:
Step-by-step explanation:
- An airplane leaves Los Angeles for Denver at a speed of 430 mph. Thirty minutes later another plane going from Denver to Los Angeles leaves Denver, which ...

Answer:
c (6)
Step-by-step explanation:
by the corresponding angles postulate, the angle above 20x-5 will be 65°.
20x - 5 + 65 = 180 <em>they are supplementary angles (angles that add up to 180°)</em>
20x + 60 = 180
20x = 120
x = 6
