Answer:
20%
Step-by-step explanation:
Divide
14/70 = 0.20
Convert from a decimal to a percent. You can multiply by 100 or move the decimal two places right.
0.20 x 100 = 20%
Answer:
2x - 0.4x ;
8x/5 ;
Yes
Step-by-step explanation:
Let number of miles = x
Arlene:
Double number of miles = 2 * x = 2x
Subtract 20% of the result :
2x - 20% of 2x ;
2x - 0.4x
Raul:
Divides Number of miles by 5 ; x / 5
Multiplies result by 8 ;
8 * (x/5) = 8x /5
To know if expressions are equivalent :
Let x = 10 miles
Using Arlene's expression:
2x - 0.4x
x = 10
2(10) - 0.4(10) = 16
Using Raul's expression :
8x / 5
(8*10) / 5
80/5
= 16
Since they give the same result, we can conclude that the expression are equivalent
It’s 2 hours 26 minutes. 60 mins is 1 hour. So 2 hours is 120 mins which leaves 26 mins behind because 146-120=26
Step-by-step explanation:
number of apartments = 4
1 apartment = 3 hours
4 apartments = 12 hours
Answer:
The answer would be 'D'. 2 x 12 + 5h
Step-by-step explanation:
In this case, you know that Bradley mows two lawns and for every lawn, he charges $12. If you were not given the number of lawns mowed, you would've had something like 12x with 12 representing the charge for every lawn mowed and x representing the actual amount of lawns mowed. However, since you were given the amount of lawned mowed (2) you can put 12(2) or 12 x 2 instead of 12x.
With this, you can eliminate every answer that does not include 12 x2 or 2 x 12. (You can eliminate answers A and B)
Now for the number of hours for the bushes trimmed. The same rules apply to this.
The variable (h) would be included here since we were not given the information on how many hours it took. 5 represents the amount that he charges for every hour and h is the unknown amount. However, if we were also given the info for this like let's say 3 hours, it would be 5(3) instead of 5x. But that's a different story.
So with this let's combine the two terms. You have 2 x 12 and 5h so, in the end, you have: 2 × 12 + 5h
I hope my explanation wasn't too confusing. I tried my best to put it in simple terms
