A new television is on sale for $680.00, which is 20% off of its original price. What was the original price of the television?
Effectus [21]

Answer:

Original price of the television = $850

Step-by-step explanation:

Television price on sale = $680.00

% of sale = 20%

It means price on sale = 80% = $680.00

Original price of the television = 100% = ?

Price on 1% = 680/80 = $8.5

Original price of the television = 100% = $8.5 x 100

                                                  = $850

I need the steps to this, please. It says solve for x. Each figure is a parallelogram. Show your work.
Trava [24]
With any parallelogram, the diagonals bisect each other. This is another way of saying that they cut each other in half.

FH is one diagonal that is split into two equal pieces by the other diagonal EG.

The two parts of FH (KH and KF) are congruent to each other, so KH = KF. They combine back to FH


By the segment addition postulate
KH + KF = FH
KH + KH = FH .... KF has been replaced with KH (works because KF = KH)
2*KH = FH

Now use substitution
2*KH = FH
2*15 = FH .... replace KH with 15 (since KH = 15)
2*15 = 4x-2 ... replace FH with 4x-2 (since FH = 4x-2)

and solve for x
2*15 = 4x-2
30 = 4x-2
30+2 = 4x-2+2 ... add 2 to both sides
32 = 4x
4x = 32
4x/4 = 32/4 ... divide both sides by 4
x = 8

Two runners start the race at the same time. The first runner's speed is
ki77a [65]

The speed of the first runner is 1.78 mph while for the second runner is 2.22 mph

<h3>Speed</h3>

Speed is the ratio of total distance to total time taken. It is given by:

Speed = distance / time

Let a represent the speed of the first runner and b for the second runner. Hence:

a = (4/5)b

After 30 minutes (0.5 hour), the runners are 2 miles apart, hence:

a = d₁ / 0.5

d₁ = 0.5a

Also:

b = d₂/0.5

d₂ = 0.5b

d₁ + d₂ = 2, hence:

0.5a + 0.5b = 2

0.5(4/5)b + 0.5b = 2

b = 2.22 mph

a = (4/5) * 2.22 = 1.78 mph

The speed of the first runner is 1.78 mph while for the second runner is 2.22 mph
