Answer:

Option (D) is correct

Step-by-step explanation:

If y is a multiple of x and versa, it will have a constant of proportionality.

Option (A)

y = (81/3)xy

y will cancel out

1=27x

It is not correct

Option (B)

y=9xy

y will cancel out

1=9x

Option (C)

y=3xy

y will cancel out

1=3x

Option (D)

y = (1/9) x

y will cancel out

x=9y

In option (D), we see that x is 9 times of x. It means it has constant of proportionality equal to 9.

Natalle is a softball coach. She has a pitching private lesson with Kasey. Kasey's mom pays Natalle $11 per hour plus a $6 tip.
kirill [66]
11t\text{ + 6 = 39}

where t is the number of hours worked by Natalle

Here, we want to write an equation that will represent the given scenario

Let the number of hours for which she earned the pay be t

From the question, she earns $11 per hour

So for t hours, the amount earned excluding the tip will be;

(11\times t)\text{ = \$11t}

Now, let us add the tip and equate to the total amount earned

We have this as;

11t\text{ + 6 = 39}

Jayden wants to lay sod on his front yard and on half of his back yard. His front yard has a length of 50 feet and a width of 70
lana [24]

The first thing we must do for this case is to calculate the area of both yards.

We have then:

front yard:

A1 = (50) * (80)

A1 = 4000 feet ^ 2

Back yard:

A2 = (10) * (30)

A2 = 300 feet ^ 2

"Jayden wants to lay sod on his front yard and on half of his back yard"

Then, the total amount will be:

A = A1 + (1/2) A2

Substituting:

A = 4000 + (1/2) (300)

A = 4000 + 150

A = 4150 feet ^ 2

Answer:

jayden needs to purchase 4150 square feet of sodd
