Mathematics
1 answer:
Sphinxa [80]3 years ago
7 0

Answer: Choice C) y = 30/x

Inverse variation equations are of the form y = k/x. In this case, k = 30. We can rearrange the format to get x*y = k after multiplying both sides by x. So y = 30/x can be turned into x*y = 30.

Alberto spent half of his weekly
maw [93]

Answer:

$8

Step-by-step explanation:

We can write an equation with the scenario given and solve for what we need, Alberto's weekly allowance.

Let his weekly allowance be "x"

Since he spend HALF of it, he spent 0.5x of it.

He has remaining also 0.5x of it

Now, whatever he has (0.5x), he gets $4 more from cleaning windows. After that he has:

0.5x + 4

This amount is equal to $8, so we can write:

0.5x + 4 = 8

0.5x = 8 - 4

0.5x = 4

x = 8

So, alberto's weekly allowance is $8

karen brought 3/8 of a gallon of ice tea to a party. Robin brought 15/16 of a gallon of ice tea to the same party. How much ice
Rudiy27

Answer:

1  5/16 gallon

Step-by-step explanation:

Gallon of ice brought by Karen = 3/8

Gallon of ice brought by Robin = 15/16

Total ice team brought by them is sum of Gallon of ice brought by Karen + Gallon of ice brought by Robin

Total ice team brought by Karen and Robin = 3/8 + 15/16

=>  3*2/8*2 + 15/16

we are multiplying with 2 both numerator and denominator in 3/8 so sas the denominator becomes 16 as in other fraction denominator is 16

=> 6/16 + 15/16

=> (6+15)/16 = 21/16

since 21/16 is improper fraction, converting it in mixed fraction we have

21/16 = 1  5/16 gallon

Thus , Karen and Robin have 1  5/16 gallon ice tea together.
