Answer:

x= 72.72 (with a line over it)

Step-by-step explanation:

(x - 5) + (1.4x) + (x) + (x + 35) = 360

Step 1. Simplify both sides of the equation.

x + 5 + 1.4x + x + x + 36 = 360

(x + 1.4x + x + x) + (5 + 35) = 360 (combine like terms)

4.4x + 40 = 360

Step 2. Subtract 40 from both sides.

(4.4x + 40) - 40 = (360) - 40

4.4x = 320

Step 3. Divide both sides by 4.4

4.4x/4.4 = 320/4.4

x = 72.72 (72 repeats, so 72 with a line over it)

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

To find out how many pages each person reads in one hour, we can use the unit rate, the number of pages read per hour.

Jeff read 10(3/4) pages in 1/2 hour.

To find out how many pages he would read in one hour, we can multiply the number of pages he read by the fraction 2/1, which gives:

= 10(3/4) x 2/1

= 21 pages per hour

Jeff read 21 pages in one hour.

Kaley read 12(1/4) pages in 1/3 hour.

To find out how many pages she would read in one hour, we can multiply the number of pages she read by the fraction 3/1, which gives:

= 12(1/4) x 3/1

= 37 pages per hour

Kaley read 37 pages in one hour.

Nikkia read 13(1/2) pages in 3/5 hours.

To find out how many pages she would read in one hour, we can multiply the number of pages she read by the fraction 5/3, which gives:

= 13(1/2) x 5/3

= 22 pages per hour

Nikkia read 22 pages in one hour.

Thus,

Jeff read 21 pages in one hour, Kaley read 37 pages in one hour, and Nikkia read 22 pages in one hour.

He paid for his breakfast with a $10 bill. Breakfast Menu Item Price 1 Breakfast taco - egg & cheese $2.00 1 Breakfast taco - with bacon $2.25 1 Order of potato hash $1.50 Cup of coffee $0.50 How much change should Jeffrey receive from a $10 bill? O A $2.75 O B. $6.50 OC. $8.50 OD. $4.25​

Answers

Answer: A.$2.75

Equation: 2(2.25)+1.50+0.50+0.75

First add the two breakfast tacos, since one is 2.25$ Two would be 4.50$ Next add the potato hash and cup of coffee, you should get 2.00$ After that add the tacos with the coffee and potato hash which equals 6.50$ and don't forget to add your 0.75. Tax to the 6.50$ once you get 7.25. You need to do 7.25. - 10.00 which would get you your change of 2.75$
