Answer:

x=5

Step-by-step explanation:

CE = EB since E is the midpoint of CB (proven by AD intersecting it).

If CE=EB, then:

2x=15-x\\

<em>Add </em>x<em> to both sides</em>

3x=15\\

<em>Divide both sides by 3</em>

x=5

bicycle costs $150. It is advertised on sale for 32% off. What is the cost savings? Solve using two different methods.
alina1380 [7]
The savings is the amount taken off or 32% of 150

32% of 150 is 0.32 times 150=48

savings is $48


or you can do
150/100=x/32
cross multiply to get
x=48


so savings is $48
