YES its 8
Step-by-step explanation:
Answer:
2x+4
Step-by-step explanation:
Distribute:
=(2)(x)+(2)(−6)+(2)(8)
=2x+−12+16
Combine Like Terms:
=2x+−12+16
=(2x)+(−12+16)
=2x+4
OMG I HAD THAT LAST YEAR LET ME LOOK FOR IT
7/k - 2 = 5/8
7/k = 5/8 + 2
7/k = 2.625
7 = 2.625k
7/2.625 = 2.625k/2.625
2(2/3) = k
k = 2(2/3)
Answer:
1. 25
2. 7
Step-by-step explanation:
Let the variables be denoted as "x".
1. If 5 times "x" is increased by 50, the result is the same as when 200 is decreased by "x".
Set the equation:
5x + 50 = 200 - x
Isolate the x. Note the equal sign, what you do to one side, you do to the other. First, add x and subtract 50 from both sides:
5x (+ x) + 50 (-50) = 200 (-50) - x (+x)
5x + x = 200 - 50
6x = 150
Next, divide 6 from both sides of the equation:
(6x)/6 = (150)/6
x = 150/6 = 25
25 is your number.

2. If 50 is decreased by 4 times "x", the result is 15 more than "x".
Set the equation:
50 - 4x = 15 + x
Isolate the x. Note the equal sign, what you do to one side, you do to the other. First, subtract x and subtract 50 from both sides:
50 (-50) - 4x (-x) = 15 (-50) + x (-x)
-4x - x = 15 - 50
-5x = -35
Divide -5 from both sides of the equation:
(-5x)/-5 = (-35)/-5
x = -35/-5 = 7
x = 7
7 is your number.
