Answer:
x = -1
Step-by-step explanation:
first you "remove the parentheses" by multiplying the number on the outside of them to everything on the inside. for instance, -2 x 2x = -4x and -2 x -6 = 12 (because whenever you multiply two negatives, it turns into a positive) then, when there is a minus sign in front of parentheses, you change the sign of everything within the parenthesis leaving you with a positive 5 and a negative 3x. so now you have a much simpler equation of -4x + 12 = 8 +5 -3x
next you want to of course add the 5 and the 8 to make it even more simple which would leave you with the equation:
-4x + 12 = 13 - 3x
The next thing you need to do is get the unknown variable on one side of the equation. So you do add 4x do get the x on the right side which would leave you with 12 = 13 - 3x + 4x
So now you can do the same thing to the 13 to try to get it on the left by subtracting 13 from both sides
12 - 13 = -3x + 4x
now you make the equation simple by "combining the like terms" (which is something you'll hear a lot in algebra class)
making you equation -1 = 1x
or just -1 = x because when you multiply something by 1, it's the same.
First, let's divide by 4, since 4 can go into both the numerator and denominator.
56/4 = 14
100/4 = 25
That gives us 14/25.
That fraction can't be reduced further, so the simplest form of 56/100 is 14/25.
Hope that helped!
Answer:
1. 60% (decrease by 40%)
3. 30% (decrease by 70%)
5. 250% (Increase by 150%)
7. 40% (Decrease by 60%)
9. 171.4% (increase 71.4%)
11. 152.6% (Increase by 52.6%)
Step-by-step explanation:
1. 20x = 11 = 0.55 rounds to 0.6 => 60%
3. 56 x = 14 = 0.25 rounds to 0.3 => 30%
5. 18x = 45 = 2.5 => 250%
7. 126x = 48 = 0.38 rounds to 0.4 => 40%
9. 42x = 72 = 1.714 => 171.4%
11. 95x = 145 = 1.526 => 152.6%
