To get the answer you have to divide the sale price $172.80 by 73%.
So first you turn 73% into a decimal by moving the decimal two places to the left turning it into .73
$172.80 divided by .73 = $236.71
You can check by then multiplying $236.71 with .73
Answer:
Step-by-step explanation:
<u>The two marked angles must have same value as corresponding angles:</u>
- 3x + 48 = 6x - 36
- 6x - 3x = 48 + 36
- 3x = 84
- x = 28
<u>The angle measure:</u>
Answer:
yards of carpet you need: 4*10/3=40/3=13.3333 yd^2
Step-by-step explanation:
convert feet to yard:
1 yard=3 feet so
12 feet=4 yards
10 feet=10/3 yard=3.33333 yard
yards of carpet you need: 4*10/3=40/3=13.3333 yd^2
The simplification of rational expression (x²+6x-7)/(x²+9x+14) gives
(x-1)/(x+2).
<h3>What is factorisation?</h3>
A polynomial or integer is simply resolved into components that, when multiplied together, produce the original or starting polynomial or integer.
- The factorization method allows us to simplify any algebraic and quadratic equation by representing the equations as that of the product or factors rather than by expanding the brackets.
- Any equation can have an integer, a variable, or the algebraic expression itself as a factor.
The given expression is -
= (x²+6x-7)/(x²+9x+14)
Factorising both numerator and denominator;
= {x+7x-x-7} / {x+7x+2x+14}
= {x(x+7)-(x+7)} / {x(x+7)+2(x+7)}
= {(x+7)(x-1)} / {(x+7)(x+2)}
Cancel the (x+7),
= (x-1)/(x+2)
Therefore, the simplification of the given equation is (x-1)/(x+2).
