14 I think.You would subtract 15-8 which is 7 and then add 7 which is 14
Because algebra means finding the unknown
it is usually used in real life
for example if if 1/2 of the legnth of a line is 8 then what is the legnth
so then 1/2 x=8 and that is algebraic
since it has x, or an unknown in it, it is an algebraic expression

Answer:
Step-by-step explanation:
Let w represent the width. Then the length is 2w-5, and the perimeter is ...
P = 2(L+W)
44 = 2((2w-5) +w)
44 = 6w -10
54 = 6w
9 = w
2(9) -5 = 13 = length
The length of the rectangle is 13 meters; the width is 9 meters.
Trevor invested $ 4720
<em><u>Solution:</u></em>
Given that, Trevor earned $ 826 on account during 2.5% annual interest for seven years
We can simple interest formula
<em><u>The formula for simple interest is given as:</u></em>
Where,
"p" is the principal
"n" is the number of years
"r" is the rate of interest
Here given that,
Principal = p = ?
rate of interest = r = 2.5 %
number of years = n = 7
Simple interest earned = 826
<em><u>Substituting the values in above formula,</u></em>
Thus he invested $ 4720
Answer:
<em><u>2/10 and 3/10</u></em>
Step-by-step explanation:
Hello!
The best way of finding common denominators is using their factors!
(of denominators)
10 : 1, 2, 5, 10
2 : 1, 2
We also can see that 10 is divisible by 2.
For that reason, 1/2 is equivalent to 2 * 10 ÷ 2.
That's 10.
So <em>5/10 and 3/10</em> have a common denominator 10.
Hope this helps!
