Let's find an eighth of 584. Break this down step by step.

584/8= 73

So, eighth equals = 73.

Now find how many seven and eighth-graders there are by multiplying 73 by the desired number.

73*5= 365 (seventh graders)

73*3= 219 (eighth graders)

So, just divide both numbers by the denominator of the fraction used, and then multiply by the numerator for the correct amount of both who participated.

365/ 5= 73

73*4= 292

292 of the seventh graders participated.

219/8= 27.375

Multiply that by the numerator.

27.375*7= 191.625 (8th graders)

The question said about how many participated, so round 191 up to 192.

292 seventh graders and 192 eighth graders participated in field day.

I hope this helps!

Determine whether each relation is a function <br> X=-2 <br> Y=2
mash [69]
X = -2 would not be a function because if you graph it, it is a vertical line. 
Y = 2 is a function because when graphed, it is shown as a horizontal line and passes the vertical line test.

Assume that y varies inversely with x. If y= 1.6 when x= 0.5, find x when y= 3.2
solniwko [45]

Answer:

x = 0.25

Step-by-step explanation:

If y varies inversely with x, then:

y \propto \dfrac{1}{x} \implies y=\dfrac{k}{x} \quad \textsf{(for some constant k)}

Given:

  • y = 1.6 when x = 0.5

Substitute the given values into the found equation and solve for k:

\implies 1.6=\dfrac{k}{0.5}

\implies k=1.6(0.5)

\implies k=0.8

Therefore:

y=\dfrac{0.8}{x}

To find the value of x when y = 3.2, substitute y = 3.2 into the found equation and solve for x:

\implies 3.2=\dfrac{0.8}{x}

\implies x=\dfrac{0.8}{3.2}

\implies x=0.25

olya-2409 [2.1K]

Answer:

1/3 - (-5/3) = 2

Step-by-step explanation:

1/3 - (-5/3)

Subtracting a negative is the same as adding a positive.
