Answer:
X =
X =
Step-by-step explanation:
Calculator!
First of all solve the fractions
1/5(15x - 20) = 3x - 4
1/3(12x - 9) = 4x - 3
3x - 4 = 4x - 3
Now you can move the X's to one side;
-4 = 4x - 3 - 3x
...And the same for the numbers;
-4 + 3 = 4x - 3x
Then solve;
x = -1
Answer: True!
We know this is true because a linear inequality uses less than/greater than and less than or equal to/greater than or equal to. This means that as long as the answer fits into the given constraints (in a graph these constraints are shown as lines and dashed lines), it is true.

Answer:
The answer is C
Step-by-step explanation:
This is because you add the two percents. 63% plus 13% gives you 76% Then you take 76% of 1200 which would give you C, 912. You can use a calculator to multiply 76% of 1200.
