-3(x - 2) = 2(x - 7) remove the parentheses
-3x + 6 = 2x - 14. Move the terms
-3x - 2x = -14 - 6. Collect like terms. Calculate.
-5x = -20. Divide both sides.
Solution: x = 4
Yes
To figure out if x = 2 is a solution, plug 2 in for x. If the left side is greater than 10, then x is a valid solution. If the left side is not greater than 10, than x is not a valid solution.
3x+5>10
3(2)+5>10
6+5>10
11>10
11 is actually greater than 10, so x=2 is a solution to this inequality
Answer:
It will take half of a day
Step-by-step explanation:
Since 12.5 is roughly half of the day, no matter what temperature is, it will take you this amount of time. You also need to include the time that you will use to take breaks and eat meals.
Answer:
Here
Step-by-step explanation:
length = x
width = 2x - 3
Perimeter = 2length + 2 width
2x + 2(2x - 3) = 42
2x + 4x - 6 =42
6x - 6 = 42
Add 6 to both sides
6x = 48
Divide both sides by 6
x = 8
Length = 8 inches
Width = 2(8) - 3 = 16-3 = 13 inches
