Answer:

x>-9

Step-by-step explanation:p

1.) Subtract 1 from both sides

-2/3x+1<7

-1<-1

= -2/3x < 6

2.) Multiple the 3 (denominator) in order to get rid of the fraction

3(-2/3x) < (6)3

= -6/3x < 18 (simplify the 6/3 into 2)

= -2x < 18

3.) Divide by -2 (when you divide with a negative number, your sin is going to switch, meaning it will turn into a '>' sign)

-2x / -2 < 18/-2

= x > -9

*ALSO*

If you want to graph it on a number line, it would look something like the picture above. (the circle is open because it doesn't have the line underneath. You're symbol also indicates which way you shade!! < = left .....> = right.....think of them like arrows :) )

Please answer this by solving it
mr Goodwill [35]

Answer:

5 5/6

Step-by-step explanation:

Change them into improper fractions.  Multiply the denominator by the whole number and then add the numerator.  Put that number over the denominator.

2 X 3 = 6           3 X 2 = 6

6 + 1 = 7            6 + 1 = 7

7/3                      7/2

New expression:    7/3 + 7/2

Find a common denominator.  Both denominators can go into 6.

14/6 + 21/6 = 35/6

Change this back into a mixed number by dividing.

Answer: 5 5/6
