Tony spent $60.54 and bought 3 packs of notebooks and a calculator. How much does a pack of notebooks cost if a calculator costs $45.87? Need equation such as 3(x+45.87)=60.54 but one that works.

Answers

Answer 1
Answer:

Let the price of a  notebook = X.

Multiply the cost of a notebook by the quantity, so you get 3x.

Add that to the price of a calculator to get the total spent:

60.54 = 45.87 + 3x

Now solve for x:

Subtract the cost of the calculator from both sides:

3x = 14.67

Divide both sides by 3:

x = 14.67 / 3

x = 4.89

A notebook cost $4.89
Answer 2
Answer:

Answer:

14.76

Two buses leave towns 948 miles apart at the same time and travel toward each other. One bus travels 10 mi h slower than the other. If they meet in 6 hours, what is the rate of each bus?

Answers

Answer:

Use a d=rt table, find x, and plug it in for the part you need. 74 & 84

Step-by-step explanation:

Create a chart for the 2 buses that shows the distance, rate, & time. Calculate the distance by multiplying the rate and time.

x is the rate of speed of the faster bus

Bus 1: D (6x) = r (x) × t (6 hrs)

Bus 2: D (6x-60) = r (x-10) × t (6 hrs)

We also know the total distance traveled was 948 miles. So 6x-60+6x=948.

Then we combine like terms.

12x-60=948

Now isolate the x term by adding 60 to both sides.

12x=1008

Divide both sides by 12 to isolate the x.

x=84

Finally, plug the x back in to the rates to determine the rate of the buses.

Bus 1 - 84 mph

Bus 2 - 74 mph

Answers

Hi there! Think of x as 2 and 6 and think of y as 8 and 12. 8-12/2-6=-4/-4. Now, -4/-4=1. Therefore, the answer is C. 1

Hello!

Step-by-step explanation:

Slope: (Y^2-Y^1)/(X^2-X^1)=(rise)/(run)

(12-8=4)/(6-2=4)=(4)/(4)=1

Slope is 1.

Answer is 1.

Hope this helps!
