X is equal to 1 in this equation. 
First add 6x and 14x together. 
20x+5=5(4x+1)
Then distribute the 5
20x+5=20x+5
subtract 5 from both sides 
20x=20x
Divide both sides by 20
x=x

Your typical markup for merchandise is 40%. your cost on an item is $8.00. calculate the selling price.
adoni [48]
The selling price would be $11.20.

40% = 40/100 = 0.4

The mark up is 40% of the cost; this means 40% of 8:

40% of 8 = 0.4(8) = 3.20
8 + 3.20 = 11.20

a biker must circle a 12 mile track twice. His average speed must be 60mph. On his first lap he averaged 50 mph. How fast must h
liq [111]

Answer:

75 mph

Step-by-step explanation:

A biker must circle a 12-mile track twice. His average speed must be 60 mph.

So, the average time required to cover the distance is \frac{2 \times 12}{60} = 0.4 hours.

Now, on his first lap, he averaged 50 mph.

So, he covered this 12 miles track in \frac{12}{50} = 0.24 hours.

Hence, he has to cover the next 12 miles track in (0.4 - 0.24) = 0.16 hours.

Therefore, his average speed in the second round must be \frac{12}{0.16} = 75 mph to qualify. (Answer)
