Which of the following equations has infinitely many real solutions?
A. 2(x - 7) = 2x + 14
B. 2(x - 7) = 2x – 14
C. 2x + 1 = 2x - 1
D. 2x + 1 = x - 1

Answers

Answer 1

Answer:

B - 2(x -7) = 2x - 14

Step-by-step explanation:

If you expand this equation, you get 2x-14 = 2x-14. This means that the equation will be true for any x, and has infinitely many solutions

Hopefully this helps! Let me know if you have any questions

If 6 pounds of grapes costs $1.89, how much would 15 pounds of grapes cost?

Answers

So divide 1.89 by 6 to see how much would one pound of grape be

Find each percent change. Round to the nearest tenth of a percent. State if it is an increase or decrease. From 79 miles to 84 miles
A) 6.3% decrease
B) 5% increase
C) 6% decrease
D) 6.3% increase​

Answers

Answer:

the answer is d.

Step-by-step explanation:

first, you want to use the formula,

new value - original value

____________________

         original value              * 100

you see that 84 is the new value and 79 would be the original value. substitute the numbers in. this is a increase since you will get a positive value.

84 - 79

______

   79      * 100

now we solve it.

5

__

79  * 100

you can either solve the fraction first then multiply that by 100 or multiply the numerator by 100 first then divide that by 79, each way works.

500

____

 79   =  approximately 6.3% increase (this is not a exact value, just rounded)

      or

5

__

79  = approximately 0.063 (this is not a exact value, just rounded)

0.063 * 100 = 6.3% increase

Robert takes out a loan for $7200 at a 4.3% rate for 2 years. What is the total paid amount at the end of the loan?

Answers

Answer:

$7819.20

Step-by-step explanation:

total paid amount at the end of the loan= loan taken + interest on the loan

loan taken = $7200

interest on the loan can be determined using this formula

Interest = principal x intrest rate x time

7200 x 0.043 x 2 = $619.20

total paid amount at the end of the loan= $7200 + $619.20 = $7819.20
