Answer:
24
Step-by-step explanation:
the simplified version of this expression would be 24
x + 1
There are 4 quarterly inches in 1 inch so 4 x7=28 + 3 quarter in 3/4 so 31 quarter inches in all.
(x-1)^3 / 2 = 27
For equations like this, we want to isolate x in order to get the value of it.
First, let's multiply both sides by 2 to eliminate the fraction.
(x-1)^3 = 27(2)
Now, let's take the cube root of both sides
(x-1) = ∛(27 * 2)
Now, simplify the root
x - 1 = 3∛2
Add both sides by 1
x = 1 + 3∛2
That's your answer.
Have an awesome day! :)
Answer:
<h2>x = 2</h2>
Step-by-step explanation:
3 - x + 1 = 2 <em>combine like terms</em>
-x + (3 + 1) = 2
-x + 4 = 2 <em>subtract 4 from both sides</em>
-x +4 - 4 = 2 - 4
-x = -2 <em>change the signs</em>
x = 2
Answer:
$420
Step-by-step explanation:
To work this out you would need to find the 25% decrease of 560. To do this you would first divide 25 by 100, which gives you 0.25. Then you would minus 0.25 from 1, which gives you 0.75. This is because when finding percentage decreases you would first have to convert it into a decimal. Then you would have to minus it from 1 , to make sure that it will be a 25% decrease not a 75% decrease. Then you would multiply 560 by 0.75, which gives you 420.
1) Divide 25 by 100.

2) Minus 0.25 from 1.

3) Multiply 560 by 0.75.
