Answer:

1/18

Step-by-step explanation:

first, you make the fraction a mixed number so 2 2/3.

second, the two minuses cancel each other out so 2 1/6 + 2 2/3

third, make the 2/3 from 2 2/3 into 4/6 so you can add it to the 2 1/6

fourth, add your 2 1/6 and your 2 4/6 to get 4 5/6.

that’s the first part: 2 1/6 -(-8/3) is equal to 4 5/6

then, since you’re adding a negative number, it’s basically subtracting the 4 7/9 from 4 5/6

first you subtract the whole numbers = 0

then, make the denominators the same: (6*9, common denominator is 54) so since you’re multipling the 9 from 7/9 by 6, also multiply the 7 by 6 to get 42. 42/54. do the same but with a 9 on the 5/6. you get 45/54

so now you can do 42/54 — 45/54 to get 3/54

54/3 is 18 so you can simplify to 1/18

Sunnyside Middle School wanted to add a new school sport, so they surveyed the students to determine which sport is most popular
ExtremeBDS [4]

Answer:

Lacrosse = 62 students

Swimming = 62 students

Soccer = 124 students

Football = 186 students

Step-by-step explanation:

Based on the information, we can draw some equations

<em>1.</em>    Lacrosse = Swimming

<em>2.</em>   Soccer = 2 * Lacrosse

<em>3.</em>   Football = 3 * Swimming

<em>4.</em>   Football + Soccer + Swimming + Lacrosse = 434

Lets solve for once sport at a time, I will start with Football.

I will put equation 1, 2 and 3 into equation 4

3Sw + 2L + L + L = 434

We can now again put equation 1 into the new equation 4

3L + 2L + L + L = 434

Simplify

7L = 434

L = 434 ÷ 7

L = 62 students

Since L = Sw, 62 students did swimming also

We can put L into equation 2 to solve for So

So = 2 * 62

So = 124 students

And now we can put Sw into equation 3 to solve for F

F = 3 * 62

F = 186 students

A motorcycle travels 3 and 1/8 miles in 2.5 minutes. Which of the following represents the rate, to the nearest mile, at which t
bonufazy [111]
The rate would be 75 miles in 1 hour.

Set up a proportion to solve this:
3 1/8 miles in 2.5 minutes gives us the ratio 3.125/2.5.
The second ratio would be x miles in 60 minutes, or x/60.

3.125/2.5 = x/60

Cross multiply:
187.5 = 2.5x

Divide both sides by 2.5:
187.5/2.5 = 2.5x/2.5
75=x

A salsa recipe uses green pepper, onion, and tomato in the extended ration 1 : 3 : 9. How many cups of onion are needed to make
Elanso [62]
Let x be a variable.

Using the ratio and the given number of 117, we can create the following formula:

1x + 3x + 9x = 117, where 3x is the cups of onion

Simplify this equation.

13x = 117

Divide both sides by 13

x = 9

We want to solve for 3x, so multiply both sides by 3

3x = 27

As I started earlier, 3x is how many cups of onions is needed; thus, 27 is our answer. Hope this helps! :)
