Answer:
<h2>-9</h2>
Step-by-step explanation:
n - a number
five more: + 5
twice a number: 2 · n = 2n
five more than twice a number: 2n + 5
The equation:
2n + 5 = -13 <em>subtract 5 from both sides</em>
2n + 5 - 5 = -13 - 5
2n = -18 <em>divide both sides by 2</em>
2n/2 = -18/2
n = -9
For this case we must simplify the following expression
We know that, by definition:
So, rewriting the expression we have:
We add similar terms taking into account that:
- Equal signs are added and the same sign is placed.
- Different signs are subtracted and the major's sign is placed:
Answer:
The length is 14 yards and the width is 77 yards.
Simple......
1.) Angelo earns $2,080... 30% is taken off...
2,080*30%=$624
Thus, $624 is taken off from his pay....answer choice A.
2.) Calculating Percent Markup...
Use these 2 formulas:
Finding Markup%...
Markup=New-Original
Markup%=
Now...start plugging in what you know!! ^-^
567 vacuums were sold this year.....540 were sold last year...
Markup=567-540
Markup=27
Now...Markup%...
Markup%=
Markup%=0.05*100
Markup%=5
Markup%=5% (Choice D)
Thus, your answer.
28 is 4 times 7, so we will rewrite it like that.
7 is 7 times 7, so we will rewrite it like that.
So the simplest form is,
