Answer:

Frederico

Step-by-step explanation:

We just look for the highest fraction

6/7 and 5/9 are both less than 1 (If the denominator is greater than the numerator, the fraction is less than 1)

11/10 is greater than 1. (If the denominator is less than the numerator, the fraction is greater than 1)

So the highest of the fractions is 11/10 and therefore Frederico has raised the most money

Answer:

Federico

Step-by-step explanation:

It is Federico because he exceeded the money needed for the school trip.

6/7 is almost enough for the trip since you needed 7/7.

5/9 is still not enough for the trip since you needed 9/9.

11/10 is more than enough for the trip since all you needed was 10/10 and you have 11/10.

Another way to solve this is to find the lowest common multiples of 7, 9, and 10 and form fractions with the same denominator.

The answer to question 34:

Let 'x' = pounds of gravel. The ratio of mulch to gravel is given 2 1/4 | 1 1/3. Which equals 9/4 | 4/3 = 27/16.



So the total gravel and much is equal to x + 27/16x = 172  


Solving for 'x'



43/16 x = 172    


x = 172 (16/43) = 64 pounds of gravel           Mulch = 27/16x = 64 (27/16)= 108 pounds

The answer to question 35:

A.) 1,080 beats per minute at rest and 1,500 beats per minute while running.

B.) 4,500 (while running) - 3,240 (at rest) = 1,260 more beats while running than at rest.

2x - 2y = 22 find the value of y when x equals 2
Vika [28.1K]

Answer:

y=-9

Step-by-step explanation:

If x equals 2, then we can substitute that into the equation, resulting in the equation 2*2-2y=22

We can solve for multiplication first:

4-2y=22

Then we can subtract four on both sides, canceling out the four on the left side:

-2y=18

Now to isolate y, we divide both sides by -2, resulting in the solution:

y=-9

Hope this helps!
