Answer:
$46
Step-by-step explanation:
A percent is a portion of 100. If we receive 25% off then we pay 75% of the price. 100%-25%=75%. $34.50 is 75% of the original price. We find the new price through a proportion. A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities. For example, we will compare percent over percent to an equal ratio of $ to $.
I can now cross-multiply by multiplying numerator and denominator from each ratio.
I now solve for y by dividing by 75.
The original price was $46.
Question:
Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.
How many days will it take Amir to catch up to Jesse, and how many pages will they each have read?
Write an equation to represent the number of pages Amir has read. Use x to represent the number of days Amir has been reading and y to represent the number of pages he has read.
Answer:
It will take 6 days
Step-by-step explanation:
For Jesse:
This implies that Jesse will cover 30y in y days
For Amir:
This implies that Amir will cover 35x in x days
Because Amir starts a day later,
So, we have the following equations:
To get the number of days when they read the same number of pages, we have:
Substitute values for Jesse and Amir
Substitute x + 1 for y

83050
Step-by-step explanation:
that's the answer to the question
7.380 times 10 to the 9th power (or 7.38 times 10 to the 9th power)
Answer:
M=-10
Step-by-step explanation:
To find the sope we use y-y1/x-x1. For this problem, I chose the first two coordinates.
(-33.5)-(-55.6)/1.20-3.45=22.6/-2.25=-10(rounded)
hope this helps!:)
