In a survey, a group of students were asked their favorite sport. Eighteen students chose “other” sports. Then how many students
Zielflug [23.3K]
18 students are 100%-37,5%-40%=22,5%
So we know that 18 students equal to 22.5. And we are looking for the anwser what 100% of students is. 
SO:
x students - 100%

(22 + 1/2)x =18×100

(22 + 1/2) can be represented as just 25.5

-//- = 1800

we need to divide bot sides by 25.5

x = 1800 / 25.5
... x = 80

Complete the sentence to explain how to use mental math to express 12/25 as a percent
Vlada [557]

Answer: It's 48%. See below.

Step-by-step explanation:

By definition, percent means out of a hundred. For instance, 10 percent is 10 out of 100.

One way to make \frac{12}{25} a percent is by making the denominator 100. In order to do so, multiply the numerator and the denominator by 4, since 25 times 4 is 100.

\frac{12}{25}  =  \frac{48}{100} = 48 %

This is very simple, and mental math is definitely possible. Hope this help.

bearhunter [10]
If a is the first term then a+99*7=710, a+693=710, a=710-693=17. The first term is 17.

8 + 4f = 3f solve for f
navik [9.2K]

Answer:

f=-8

Step-by-step explanation:

8+4f=3f

8+4f-4f=3f-4f (Subtract 4f from both sides of the equation to isolate f)

8=-f (Simplify)

-f=8 (Symmetric Property of Equality)

\frac{-f}{-1} =\frac{8}{-1} (Divide both sides of the equation by -1 to get rid of f's coefficient; remember that -f=-1*f, so -f has a coefficient of -1)

f=-8 (Simplify)

Hope this helps!
