Answer 2

Okay, thanks!
First Question:
The difference between twice a number and two is 10. Write and solve an equation to determine the number

A. x = 4
B. x = 6
C. x= 7
D. x= 9

Answer 3

Do you have any idea on how to setup the equation?

Answer 4

Not really.

Answer 5

"Difference" implies that you need a "minus". And twice is 2 times something (x). So it would look like this \[2x-2=10\] Does that make sense ?

Answer 6

yes you 10-2=8 divide by 2 giving you what ?

Answer 7

4?

Answer 8

Yea, correct. \[x=4\]

Answer 9

good job

Answer 10

The sum of 1 and 3 times a number is 22. Write and solve an equation to determine the number.

A. x=4
B. x=6
C. x=7
D. x=9
Can you walk me through it again?

Answer 11

Setup the equation. The sum: implies additions, and then we have 3 times a number. So the equation would look like this:\[1+3x=22\]

Answer 12

7?

Answer 13

Correct

Answer 14

Okay. Next Question:
