15x-24

the answer is not B because 3*-5= -15, we need -24

the answer is not C because 3*-24= -72

the answer is not A because 5*8= 40

Answer :

D. 3(5x − 8)

(3)(5x)(3)(-8)

15x-24= 15x-24

Answer: OPTION D.

Step-by-step explanation:

Given the following polynomial:

15x - 24

You can find an equivalent expression by factoring out the Greatest Common Factor (GCF).

In order to find the Greatest Common Factor, you need to descompose the coefficients 15 and 24 into their prime factors:

15=3*5\\24=2*2*2*3=2^3*3

You can observe that the Greatest Common Factor is:

GCF=3

Then, factoring out 3, you get:

3(5x-8)

Which ordered pair is a solution of the equation? y = 7 x − 3 y=7x−3
eimsori [14]

Answer:

(1,4)

Step-by-step explanation:

Which ordered pair is a solution of the equation? y = 7 x − 3

a. (1,4) b. (-1,-4) c. both d. neither

Solution

y=7x-3

Solve by trying each ordered pair

a. (1,4)

x=1, y=4

Substituting the value of x and y into the equation

y=7x-3

4=7(1)-3

4=7-3

4=4

This is a true statement

b. (-1,-4)

x=-1, y=-4

Substitute the value into the equation

y=7x-3

-4=7(-1)-3

-4= -7-3

-4= -11

This is not a true statement

This true statement is when x=1 and y=4

So, the ordered pair (1, 4) is the solution

Johnson’s Hardware randomly selects 125 of its customers and questions them to determine their overall customer satisfaction rat
Sphinxa [80]

Answer:

a. 92%

b. 4425

Step-by-step explanation:

So there are 5000 customers in total, and 100 were completely satisfied, and 15 were satisfied and 10 weren't satisfied a bit. so 100+15 is 115 so 115 people in total were satisfied out of 125 because there were 125, and 115+10 is 125 anyways. So 115/125 is .92, and you can convert that into a percentage, 92% of the 250 customers were satisfied so then 250*5 is 5000, so then just multiply 115 by 5 as well. You get 575. So 575 were satisfied out of the 5000 customers and 5000-575 are the people not satisfied, so 4425.

probably wrong because it doesnt sound right but just try it
