Answer:
73%
Step-by-step explanation:
Let us have the original price as $100
A discount of 27% will be;
27/100 * 100 = $27
so, the value to be paid will be $100 - $27 = $73
Now, what percentage of $100 is the $73 that was paid
that would be;
73/100 * 100% = 73%
We can substitute<span> y in the second equation with the first equation since y = y. The solution of the linear system is (1, 6). You can use the </span>substitution<span> method even if both equations of the linear system are in standard form</span>
Answer: (1/3)=0.33 repeating
(3/4)=0.75
Step-by-step explanation: Think (3/4) of it as quarters. 3 quarters made 0.75¢. And (1/3) is just a repeating decimal, which is 0.333333... and so far more.
Answer:
x =
Step-by-step explanation:
The absolute value always returns a positive value but the expression inside can be positive or negative, that is
x + 4 = 3x - 5 ( subtract 3x from both sides )
- 2x + 4 = - 5 (subtract 4 from both sides )
- 2x = - 9 ( divide both sides by - 2 )
x =
OR
-(x + 4) = 3x - 5
- x - 4 = 3x - 5 ( subtract 3x from both sides )
- 4x - 4 = - 5 ( add 4 to both sides )
- 4x = - 1 ( divide both sides by - 4 )
x =
As a check
Substitute these values into the equation and if both sides are equal then they are the solutions
| + 4 | = | | =
right side = - 5 =
left side = right side , thus x = is a solution
check second solution
| + 4 | = | | =
right side = - 5 = -
right side ≠ left sides, hence not a solution
