X-5y=2 and 9x+8=15 solve by substitution

lozanna [386]

$x-5y=2$
Hence $x=2+5y$ (Equation I)
$9x+8=15$ (Equation II)
Substituting Equation I in Equation II
$9(2+5y)+8=15$
$18+45y+8=15$
$26+45y=15$
$45y=-11$
Hence $y= - \frac{11}{45}$

Substituting this in Equation in I to get X

$x-5(- \frac{11}{45} )=2$
$x+ \frac{11}{9}=2$
$x= 2- \frac{11}{9}$
$x= \frac{17}{9}$

A red car usb traveling 55mph for 206.35 miles how long does it take the car to arrive at is destination

Nataliya [291]

Hi there!

"mph" stands for "miles per hour".

This means that the car travels 55 miles in 1 hour.

To find your answer, you'll need to use the cross product method :

55 miles → 1 hour

206.35 → x

(1 × 206.35) ÷ 55 = x

206.35 ÷ 55 = x

206.35 ÷ 55 = 3.751818...

206.35 ÷ 55 ≈ 3.75

0.75 × 60 = 45 minutes

Your answer is: It takes 3 hours and 45 minutes for the car to arrive at its destination.

There you go! I really hope this helped, if there's anything just let me know! :)
