5(3y)-y=75 -> 15y-y=75 -> 14y= 75 -> y= 75/14
3(75/14)=x -> x= 225/14 and y= 75/14
I'm completely wrong but i tried
The first equation uses the first and second coupons. the coupon (1-y)40 will take y% off of the dress pants so the answer is 40(1-y)
Answer: $5289.35
Step-by-step explanation:
Since the cars have an average mileage of 6.78 miles per gallon and the race is 500 miles, the number of gallons each car will take will be:
= 500/6.78
= 73.75 gallons
Since they're 44 cars, the total gallons of fuel will be:
= 44 × 73.75
= 3245 gallons
Since the fuel cost is $1.63 per gallon, the total fuel cost, will be:
= $1.63 × 3245
= $5289.35
Answer: x=0
Step-by-step explanation: -1.2(3x-3) = 4(3x+0.9) -3.6x+3.6=12x+3.6 -3.6x-12x+12x=12x+3.x+12x -15.6x+3.6-3.6=3.6-3.6 -15.6x/-15.6=0/-15.6 x=0
So I think that it is 9
