Answer:
35
Step-by-step explanation:
Let's call the original price X
14% of x is equal to $4.90 to calculate 100% of the price we multiply 100 with 4.9 then divide it with 14
4.9 × 100 ÷ 14 = 35
She would pay 15 dollars for the dress because it would be 75 percent off.
Answer:
The value of x is 4
Step-by-step explanation:
A full rotation is = to a total of 360 degrees so if you have
280 and 2x you place them into an equation to find x
The equations would be
2x + 280 = 360
since both of them combined should be 360
now we solve with simple algebra
2x + 280 = 360
subtract 280 from both sides
2x = 80
divide both sides with 2
x = 40
meaning
The value of x is 4
Answer:
10 mph
Step-by-step explanation:
The distance traveled by A + the distance traveled by B = the total distance
Since distance = rate × time:
20 × 5 + B × 5 = 150
100 + 5B = 150
5B = 50
B = 10
B must travel at 10 mph.
