Simplify 5m-2(6m-5)+2 a. -7m-8 b. -7m+12 c. 17m+12 d. 17m-8

fgiga [73]

The answer is B. -7m+12.

First distribute the -2 to 6m and -5.

5m-2(6m-5)+2

5m+(-2*6m)+(-2*-5)+2

5m+-12m+10+2

After that, combine the like terms.

5m+-12m+10+2

-5m+-12m=-7m

10+2=12

The simplified expression is -7m+12.

If 5 sips +4 gulps = 1 glass and 13 sips +7 gulps = 2 glasses, how many sips equal a gulp?

nataly862011 [7]

Answer:

3 sips equal a gulp

Step-by-step explanation:

we have

$5sips+4gulps=1glass$ ----> equation A

$13sips+7gulps=2glass$

Divide by 2 both sides

$6.5sips+3.5gulps=1glass$ ----> equation B

equate equation A and equation B

$5sips+4gulps=6.5sips+3.5gulps$

Group terms that contain the same variable

$4gulps-3.5gulps=6.5sips-5sips$

$0.5gulps=1.5sips$

$gulps=(1.5/0.5)sips$

$gulps=3sips$

therefore

3 sips equal a gulp
