It is 70 because common sense people
2kg=2000g so do 275/2000 and cancel down to 11/80 :)
Answer:
y=1/2x-5
Step-by-step explanation:
We have slope so we just need to find the y intercept.
slope intercept formula is
y=mx+b
(m) is slope
(b) is y int
y=1/2x+b
now apply our given x and y values (4 & -3)
-3=1/2(4)+b
simplify
-3=2+b
subtract 2 from each side
-5=b
put that into our equation
y=1/2x-5
First equation
L.H.S = 4x -0.25y
so it doesn't equal the R.H.S
2nd equation
R.H.S = 15q + 3qr
so it doesn't equal the L.H.S
3rd equation
R.H.S = -30m -60n
so R.H.S doesn't equal L.H.S
4th equation
L.H.S = -16a +4
so L.H.S equal R.H.S
The answer is D
Answer:
C - 2 2/9
Step-by-step explanation:
7 1 /2 x + 3 2/ 3 = −13
Subtract 3 2/3 from each side
7 1 /2 x + 3 2/ 3 - 3 2/3 = −13 - 3 2/3
7 1/2x = -16 2/3
Change each mixed number to an improper fraction
7 1/2 = (2*7 +1)/2 = 15/2
16 2/3 = (3*16+2)/3 = 50/3
15/2 x = -50/3
Multiply each side by 2/15 to isolate x
2/15 * 15/2 x = -50/3 * 2/15
x = -100/45
Simplify
x = -20/9
Change back to a mixed number
9 goes into 20 2 times with 2 left over
x = -2 2/9
