Answer,

Slide 1: 8x − 7 = 3x + 8

Slide 2: x = 3

Slide 3: Not sure, but I'm still working on it :-)

Explanation,

Slide 1:

Simplify both sides of the equation.

6x + x + x − 5 − 2 = 8 + 2x + x

6x + x + x + −5 + −2 = 8 + 2x + x

(6x + x + x) + (−5 + −2) = (2x + x) + (8) (Combine Like Terms)

8x + −7 = 3x + 8

8x − 7 = 3x + 8

Slide 2,

(Take the equation from above & contiue the work)

Subtract 3x from both sides.

8x − 7 − 3x = 3x + 8 − 3x

5x − 7 = 8

Add 7 to both sides.

5x − 7 + 7 = 8 + 7

5 x = 15

Divide both sides by 5.

5x/5 = 15/5

X = 3

Hope This Helps :-)

I WILL GIVE BRAINLIEST! PLEASE HELP ME!

PilotLPTM [1.2K]

needless to say that the conversion from miles to kilometers uses a constant value, and therefore, they're directly proportional.

now, I could write the direct proportional relation blah blah but there's no need, we can simply squeeze it out of the table by simply checking how many kilometers there are in 1 mile.

well, we know that 11.0 miles give us 17.699 km, ok hmmm if we divide 17.699 ÷ 11 = 1.609.

if we do the same on table for 26 and 41.834, so 41.834 ÷ 26 = 1.609, and the next pair 54.706 ÷ 34 = 1.609, the value of 1.609 is consistent or constant, or namely that there are 1.609 kilometers in 1 mile.
