Answer:
x=−1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x−
8
2
=x−6
3x+−4=x+−6
3x−4=x−6
Step 2: Subtract x from both sides.
3x−4−x=x−6−x
2x−4=−6
Step 3: Add 4 to both sides.
2x−4+4=−6+4
2x=−2
Step 4: Divide both sides by 2.
2x
2

x=−1
Answer:
see below
Step-by-step explanation:
Part A
d=rt
Divide each side by t
d/t = rt/t
d/t = r
Part B
d =800000 meters and t = 4 hours
800000 meters / 4 hours = rate
200000 meters / hour = rate
Part C
We know that 1000meters = 1 km
200000 meters / hours * 1 km/1000m = 200 km / hour
Part D
We should use km because km is used to measure long distances and 200000 meters is a long distance.
Answer:3.0059 , 3.601 , 3.06
Step-by-step explanation:
the number with less digits behind the decimal has less value
Answer:
x > -2
Step-by-step explanation:
3(x + 2) > 0
Expand the brackets.
3x + 6 > 0.
Subtract 6 on both sides of the inequality.
3x + 6 - 6 > 0 - 6
3x > -6
Divide 3 into both sides of the inequality.
3x/3 > -6/3
x > -2
Answer:
144620453 cubic yards
Step-by-step explanation:
the side lengths of the cube are 524.9
the equation for the volume of a cube is the side length to the third power
so V=s^3
then plug in the number
V=524.9^3 plug into a calculator to get 144620453.2 then round to the nearest cubic yard so the answer is 144620453 cubic yards
Hope this helps! :)
