In 1992, Jason bought a gallon of gas for $1.20. Yesterday, he bought a gallon of gas for $2.22. What is the percentage increase of the price of a gallon of gas from 1992 to yesterday? If necessary, round to the nearest tenth of a percent. A.
54.1%
B.
15%
C.
45.9%
D.
85%

A.

Step-by-step explanation:

(I'm not sure if this is right so let me know)

If you divide 1.20 by 2.22 it comes out as 0.5405. If you take this and round, you get 0.541. After this, to make it a percentage, you move the decimal 2 places left, which comes out as 54.1%

Hope this helps!

answer: '

the distance between points l and m

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
