As a Fraction: 68/80 = 34/40 = 17/20
Decimal = 17/20 = 0.85
Percent = 0.85 * 100 = 85%
Hope this helps!
300,000,000+4,000,000+800,000+400
40x+35=y
x is the amount of months, y is the total price.
for 10 months just plug in 10 for x
40(10)+35=y
y=$435
X^2 - 14x + 42 = 0
x^2 - 14x = -42
x^2 - 14x + 49 = 49 - 42
(x - 7)^2 = 7
x - 7 = (+-) sqrt 7
x = 7 (+-) sqrt 7
solutions are : x = 7 + sqrt 7 and x = 7 - sqrt 7
Answer:
The simplified expression for the given expression will be:
c.
Step-by-step explanation:
Given expression:
To simplify the expression.
Solution:
In order to simplify the expression, we will first remove the parenthesis by reversing the signs of the terms inside the parenthesis which lies after a negative sign out side the parenthesis.
<em>This is because negative multiplies to a negative to give a positive and negative multiplies to a positive to give a negative.</em>
So, we have:
⇒
Combining like terms
⇒
<em>The like terms can be evaluated as</em>
Thus, the simplified expression will be:
⇒
