Answer:
14) y = 81
15) n = 6
Step-by-step explanation:
14)
54:30 = y:45
cross multiply: 45(54) = 30y, so y = 81
15)
6:3 = 12:n
cross multiply: 12(3) =6n, so n = 6
I’m not 100% sure I’m correct on this but when she started at 12,584 miles, her tank was full. After driving, it was at 12,584 miles which is a difference of 208 miles. So if you put that into a fraction: it would be 31.12 dollars/208 miles, Which means every 31.12 dollars spent, she is able to drive 208 miles. Now all you need to do is simplify that. If you divide 31.12 by 208, you get around .149. That rounded would be about .15 gallons of gas. So every (and I don’t know if t tells you to round or not so be careful on that) .149 dollars, (not 149, it’s .149) she goes one mile.
F(x) has a greater slope.
Explanation: when graphing g(x) on a graphing calc, you will see that the slope is 2/2, which is less than a slope of 4.
Hope this helps!!
Answer:
$360 on game console
$480 on tv
$1440 before spending money
x - 1/3x - 1/4x = $600
12/12x - 4/12x - 3/12x = $600
5/12x = $600
x = (12/5)($600)
x = $1440
Game Console = (1/4)(1440) = $360
Hope this helped!
