Answer:
y = -2/5 or y = 1
Step-by-step explanation:
(5y + 2)(y-1) = 0
(5y+2) = 0
Subtract 2 on both sides.
5y = -2
Divide 5 into both sides.
y = -2/5
(y - 1) = 0
Add 1 on both sides.
y = 1

Answer:well you see this is easy first you look at the 113 divide that by 4 multiply by 2 and then square root and you have your answer which would be d <4
Step-by-step explanation:
X+2y=10
6x+6y=6 -> x+y=1
(x+2y=10)-(x+y=1)=y=9
x+(2*9)=10
x+18=10
x=-8 and y=9 -> c
Answer:
smallest amount of sugar = 40 kg
largest amount of sugar = 80 kg
Step-by-step explanation:
2 : 3 : 4
2 + 3 + 4 = 9
180 ÷ 9 = 20
Therefore,
2 : 3 : 4 = (2 x 20) : (3 x 20) : (4 x 20) = 40 : 60 : 80
So the smallest amount of sugar = 40 kg
and the largest amount of sugar = 80 kg
