Multiply 140 * .25 = 35
Subtract your discount from the Price
140-35=105
<u>Sale price is $105</u>
So she earned $34 in 4 hours, meaning she was earning at the rate of 34/4 or $8.5/hour. Is she works for 10 hours at the same rate, it would be 8.5 x 10 = $85. B is the correct proportion.
Lizette ran for 1.25 hours and walked for 3 hours.
distance = speed × time
Her total distance is the sum of her distances at the different speeds. Let w represent her walking speed in mi/h. For distances in miles, speeds in miles per hour, and time in hours, the problem statement tells us ...
19 = (w+5)(1.25) + (w)(3)
19 = 4.25w + 6.25 . . . . collect terms
12.75 = 4.25w . . . . . . . subtract 6.25
3 = w . . . . . . . . . . . . . . . divide by 4.25
Lizette's walking speed is 3 mph.
Lizette's running speed is 8 mph.

answer: x^9
x^7 * x^(8/4)= (x^3)(^6/2)
x^7 * x^2= x^3*3
x^9=x^9
exponents are added when there are variables associated with them, and are multiplied directly when like the right side
