Which proportion could be used to solve the question? What percent of 80 is 23?

A. p/23 = 80/100

B. p/80 = 23/100

C. p/100 = 23/80

D. none could be used

C. can be used to solve it

other way is: p/100 *80 = 23

0.8p = 23

p = 23/0.8 = 28.75

HELP ASAP PLEASE! Find the slope and reduce.

P=(2,3) Q=(9,7)

Slope of PQ = ?

*answer must be a fraction*

M= (y2-y1)/(x2-x1)

Plug in the points. (2,3) (9,7)

m= (7-3)/(9-2)

m= 4/7

Slope= 4/7

I hope this helps!

What does this equation equal to | -9 + 4 | =

The absolute value sign changes anything that's in it to become a positive number. So -9 + 4 is -5. The | | will make the -5 becomes positive. So |-5| = 5.

Your answer is 5.

Your answer is 5.

Absolute value indicates that we are focusing on the distance, not the direction. Which means that the sign will not be included.

l-9+4l

-9+4 = -5

l-5l Absolute value of -5 is 5.

Answer: 5

l-9+4l

-9+4 = -5

l-5l Absolute value of -5 is 5.

Answer: 5

What is the least number you could multiply by to write an equivalent equation with integer coefficients? 1/3(4a+1)=1/2a

Multiply both sides of the equation by _____ .

The least common multiple of the divisors 3 and 2 is 6. Multiplying by 6 gives you

2(4a+1) = 3a

Multiply both sides of the equation by 6.

2(4a+1) = 3a

Multiply both sides of the equation by 6.

The positive integer x is a multiple of 9 and also a multiple of 12. The smallest possible value of x is

(A) 3

(B) 12

(C) 21

(D) 36

(E) 72

X is multiple of 9 as well as 12.

Thus, smallest value will be 36 ( 9 *4 = 36, 12 * 3 = 36)

3 and 12 are not the multiples of 9.

72 is a larger multiple than 36; thus, the correct answer is 36.

Thus, smallest value will be 36 ( 9 *4 = 36, 12 * 3 = 36)

3 and 12 are not the multiples of 9.

72 is a larger multiple than 36; thus, the correct answer is 36.

What are the earnings for:

1. 5 days at $69.00 a day = $

2. 3.5 days at $27.75 a day = $

Answer:

1. 345 dollars

2. 97.125 dollars

Step-by-step explanation:

1) What are the earnings for 5 days at 69 dollars a day?

If a person makes 69 dollars a day and we want to know the earning of 5 days, we would have to multiply the earnings per day by the number of days.

69 x 5 = 345.

2) What are the earnings for 3.5 days at 27.75 dollars a day?

If a person makes 27.75 dollars a day and we want to know the earning of 3.5 days, we would have to multiply the earnings per day by the number of days.

27.75 x 3.5 = 97.125

1. 5*69$ = 345$ , the earning is 345 dollars.

2. 3.5*27.75 = 97.125$, the earning is 97.125 dollars.

2. 3.5*27.75 = 97.125$, the earning is 97.125 dollars.
