Answer:

the answer is A

Step-by-step explanation:

410 is the total amount paid

so 50 dollars was a base fee for the service charge

and 90 was per tire. Because we dont know how many tires she bought 90 x number of tires(t) = 90t

so 410 dollars = 50 dollars(service fee) + 90 dollars ( multilied by number of tires "t")

Area of the trapezoid:
$\frac{12.8 + 4.2}{2} (4.9) = 41.65 cm^2$

Area of the rectangle:
4.2 x 3.1 = 13.02 cm^2

Area of each quarter circle:
$\frac{ \pi (3.1)^{2} }{4} = 7.54 cm^2$

We have two quarter circles:
7.54 + 7.54 = 15.08

41.65 + 13.02 + 15.08 = 69.75 cm^2

Put the following equation of a line into slope-intercept form, simplifying all fractions. 5x+6y=42

Sever21 [200]

Answer:

$y=-\frac{5}{6} + 7$

Step-by-step explanation:

Slope-intercept formula requires us to isolate the y variable. We can do this in just a couple of steps.

1) Move 5x from the left to the right side by subtracting 5x from both sides. This cancels out the 5x on the left side, and remember, what we do to one side we must do to the other to keep the equation balanced.

$6y=-5x+42$

2) Divide both sides by 6. Again, we are cancelling out the 6 on the left but we must also divide on the right. This would mean dividing -5 and 42 by 6 to get:

$y=-\frac{5}{6} + 7$
