When a number is decreased by 4.5%, the result is 90. What is the original number to
the nearest tenth?

x = 94.2

Step-by-step explanation:

Let x represent the number

x - 4.5%x = 90

x - 4.5/100x = 90

x - 0.045x = 90

0.955x = 90

Divide both sides by 0.955(the coefficient of )

x = 90/0.955

x = 94.2

what is the question?

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
