Try proportions. It can help since it's asking for the "cost". Hope this helps! :)
Answer:
LCM(9, -1, -1, +2, +2, +2) = 2×3^2 = 18
Step-by-step explanation:
9 = 32
-1 = -1
-1 = -1
+2 = 2
+2 = 2
+2 = 2
LCM = 2×3^2 = 18
18 / 9 = 2
18 / -1 = -18
18 / -1 = -18
18 / +2 = 9
18 / +2 = 9
18 / +2 = 9
I believe the value of y is -28
also believe m
25 is 57.4
3.14x

x250x.5= 3,925,000
3,925,000 divided by 1000= <u>3925 litres
