2x-y=2--------------(i)
2x-2y=4------------(ii)
Multiplying eqn i by 2 and subtracting with ii
4x-2y=4
2x-2y=4
- + -
________
2x=0
X=0
Putting the value of x in i
2×0-y=2
-y=2
y=-2
Hence the value of x is 0 and y is -2
Answer:
2 2/9 yards or 20/9 yards
Step-by-step explanation:
Slimy went 4 times as much as Speedy did so that means 5/9 x 4 yards which is the same thing as 5 x 4/9 so 5 x 4/9 equals 20/9 or 2 2/9 so Slimy crawled 2 2/9 yards.
Answer:
Step-by-step explanation:
Given Data,
Q=23000 J
c=4.184 J/g °c
Δt= 68 °c
m=?
By using this equation,
Q=mcΔt
Answer: M= 3/5
Step-by-step explanation: 3/5x=3= M=3/5
"17 less than" implies subtraction of the product of 3 and m, so the equation would be, if solving for x:
x=3m-17
