Take 40 divided by 2.5 which is equal to 16.
16 meters is your final answer
Well, there are 3 feet in a yard so you can just divide the number of yards by 3.
10x - 18y = 84 6=x substitute 6 for x so its 6 * 10
60 - 18y = 84 subtract 60 from both sides
-18y = 24 divide by -18
y = -1 1/3
check!
60 + 24 = 84
84 = 84
x=−2 and y=−4
