Write the expression. Then, check all that apply. six times the sum of nine and a number Replace "a number with the variable, n The two operations are multiplication and addition The two operations are multiplication and subtraction Key Words Replace With six 6 The constants are 6 and 9 times The expression is written as 6n + 9 The expression is written as 6/9 + n) the sum of nine 9 a number

A,B,D,F

A. Replace "a number with the variable, n

B. The two operations are multiplication and addition

C. NO

D. The constants are 6 and 9

E. NO

F. The expression is written as 6(9 + n)

Step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
