A certain common formula converts the numbers in Box 1 to the corresponding ones in Box 2. Another formula then converts the numbers in Box 2 to the corresponding ones in Box 3:
IMAGE
If we wanted to convert a number m in Box 1 directly to the corresponding number in Box 3, we could use the formula.
A. 3m + 2
B. 3m x 3
C. 3(m + 2)
D. m + 2 x 3
The formula to convert numbers from box 1 to box 3 is (c) 3(m + 2)
Represent the numbers in box 1 with m.
The numbers in box 2 are three times the numbers in box 1.
So, the formula to convert numbers in box 1 to box 2 can be represented as:
[tex]f(m) =3m[/tex]
The numbers in box 3 are 6 more than the numbers in box 2.
So, the formula to convert numbers in box 2 to box 3 can be represented as:
[tex]g(m) =f(m) + 6[/tex]
Substitute 3m for f(m)
[tex]g(m) =3m + 6[/tex]
Factor out 3
[tex]g(m) =3(m + 2)[/tex]
Hence, the formula to convert numbers from box 1 to box 3 is (c) 3(m + 2)

You go to the movies with five friends. You and one of your friends each buy a ticket and a bag of popcorn.
The rest of your friends buy just one ticket each. The expression represents the situation.
Evaluate the expression when tickets cost $7.25 and a bag of popcorn costs $3.25.
Answer:
$42.75
Step-by-step explanation:
2 people buy a ticket you and one friend so = $21
Then you have three friends who have not bought anything. we are told that each only buys a ticket so 3(7.25)=21.75
then add the two outcomes 21.75 + 21 and get $42.75
total equation: 5(7.25)+2(3.25)

HOPE OT HELPED
Answer:
1. : 4
2. : 15
Step-by-step explanation:
Factors for 20: 1, 2, 4, 5, 10, 20
Factors for 32: 1, 2, 4, 8, 16, 32
Looking at the factors, we can see that the largest factor 20 and 32 have in common is 4. The answer isn't 1 or 2 because we are looking for the greatest common factor. This means we are looking for the largest of the factors which they both share.
Factors of 45: 1 , 3 , 5 , 9 , 15 , and 45.
Factors of 75: 1 , 3 , 5 , 15 , 25 and 75
Looking at these factors, we can see that 15 is the largest factor that 45 and 75 both share. The answer is not 1, 3, or 5 because we are again looking for the GREATEST common factor.
