Answer: 180 = 30 + (x + 60)
Step-by-step explanation: Supplementary means that the angles add together to 180 degrees. This equations shows that angle A (30 degrees) plus angle B (x + 60) equal 180. If you solve the equation you will find that angle B is equal to 150 degrees, and that x = 90.
287/2 is 143.5 This is a picture of how it's solved
Strictly speacking, since 'c' is defined in the statement this shoudl work:
Part 1) According to the exercise, the letter 'c' represents the total cost of the three pounds of oranges. So c is the total cost of the three pounds of oranges.
Part 2) Rami has three pounds of oranges. In order to know how much a pound of oranges cost, he will have to divide by 3 the total cost of the three pounds 'c'
Part 3) The cost per pound is:
cost 1 pound of oranges = c/3
Answer:
x = ±3
Step-by-step explanation:
2 = |x| - 1
Add 1 to both sides: |x| = 3
⇒ x = ±3
