60/8 = 7.4. The dog is faster. 35/5 = 7
Area of basketball court: 94 x 50 = 4700 square feet
area of football field: 360 x 160 = 57600 square feet
57600 / 4700 = 12.26
so 12 basketball courts
I would solve the first equation for x and then sub that value into x in the second equation. That's the easiest way. x - 2y = 3 solved for x is x = 2y+3. Now sub that in for x in the second equation: 5(2y+3)+3y=2 and 10y + 15 + 3y = 2. 13y = -13, and y = -1. Now sub that y value into either equation to solve for x: x = 2(-1) + 3 gives us an x value of x = 1. Therefore, your solution to this system is (1, -1), first choice above.
I got 3.75. not sure if it’s right but hope i helped
