Add 6.9 to both sides.
This is the new equation: 4.8y=10.08.
Next, divide both sides by 4.8.
new equation: y=2.1
Hope this helped!!
<span>Note D = r(t)
20min = 1/3 hr and 10min = 1/6 hr
(1/3hr)30mph + (1/6hr)3mph = 10.5 mi, the total distance traveled.
total distance / total time = average speed = 10.5/(1/3 + 1/6) = 10.5/(2/6 + 1/6)
10.5mi/.5hr = 21mph
Hope This Helps

D){x+8y=369{y=8x D is the answer
2x^2 + 5x - 12 = 0
2x^2 + 8x - 3x - 12 = 0
2x(x + 4) - 3(x + 4) = 0
(2x - 3)(x + 4) = 0
2x - 3 = 0 or x + 4 = 0, so:-
solution is 3/2, -4.
12 months in a year.
$20 a month.
20*12=240
He'd spend 240 dollars.
