8.8 + 7.8x = -7.9 - 5.5x

Step-by-step explanation:

Step 1: Collect the like terms

8.8 + 7.9 = -5.5x - 7.8x

Step 2: Simplify

16.7 = -13.3x

Step 3: Divide both sides by -13.3

Therefore the answer is

  x = -1 34/133

Step-by-step explanation:

Given

  8.8 +7.8x = -7.9 -5.5x

  13.3x = -16.7 . . . . . . . . . . . add 5.5x -8.8

  x = -16.7/13.3 = -167/133 . . . . divide by 13.3 and simplify

  x = -1 34/133 ≈ -1.25564

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
