An algebraic expression is, obviously, an expression with a variable.
"A number" would represent a variable, which, in this case, we'll use y.
So, 15 decreased by twice x.
15 - y x 2 =
I hope this helped :)
Answer:
Step-by-step explanation:
12.66-n=7.64
12.66-7.64=n
5.02=n
So you already know the difference between the new number and original number, so all you have to do now is plug it in to this: Percentage Change=Difference/Original Number x100. So 17.99/257=.07x100 which equals 7%. So B is the correct answer.
Answer:
11
Step-by-step explanation:
You don't need the parenthesis, so you get:
2 5/8 + 4 8/17 + 9/17 + 3 3/8
You combine the integer values and get:
9 + 5/8 + 8/17 + 9/17 + 3/8
You combine the fractions with the denom. of 8 and do the same with those with the denom. of 17 and get:
9 + 8/8 + 17/17
You simplify:
9 + 1 + 1 =
11
Answer:
Step-by-step explanation:
<u>The first time:</u>
- 16 m up and 16 m down = 32 m
The second time and each time after, half of the previous distance
<u>This is a GP with the first 6 terms:</u>
<u>Sum of the distances:</u>
- 32 + 16 + 8 + 4 + 2 + 1 = 63 m
