Answer:

I think the answer would be best supported with an equation. Then everything will fall into place

Step-by-step explanation:

We have a pre-set amount of $800. That will not change.

The key word here is each. It costs $15 to print <em>each</em> yearbook. Each depends on how many yearbooks are bought.

We will use y to represent the amount of yearbooks bought, and t to represent the total cost.

Equation:

800 + 15y = t

<u>Let's try an example:</u>

<em>The yearbook club finds that 50 people have decidedly bought yearbooks! They are so excited! But they have a problem. They don't know how much the whole thing is going to cost: the yearbook software cost AND the amount they must spend on printing each yearbook. What is the total cost?</em>

So we have an equation: 800 + 15y = t. Now we just substitute in the numbers and voila! We get our answer. Let's solve!

800 + 15y      = t

800 + 15(50) = t      (y is the amount of yearbooks bought. 50 people

800 + 750     = t       bought yearbooks).

1150               = t      (t is the total cost of everything).

Our total cost is $1150! That is how much it'll cost to make all the yearbooks, including the yearbook software.

I hope this helps!

A dog weighs 2 pounds less than 3 times the weight of a cat. The dog weighs twenty two more pounds than the cat
Nesterboy [21]

Complete Question

A dog weighs 2 pounds less than 3 times the weight of a cat. The dog weighs twenty two more pounds than the cat.

Write and solve an equation to find the weights of the cat and the dog.

Answer:

Weight of cat = x = 12 pounds

Weight of Dog = y = 34 pounds

Step-by-step explanation:

Let's represent:

Weight of cat = x

Weight of Dog = y

A dog weighs 2 pounds less than 3 times the weight of a cat.

y = 3x - 2........ Equation 1

The dog weighs twenty two more pounds than the cat

y = x + 22....... Equation 2

The equation is given as:

y = y

3x - 2 = x + 22

Collect like terms

3x - x = 22 + 2

2x = 24

x = 24/2

x = 12 pounds

Solving for y using any of the equations:

y = 3x - 2

y = 3 × 12 - 2

y = 36 - 2

y = 34 pounds

Therefore:

Weight of cat = x = 12 pounds

Weight of Dog = y = 34 pounds

H = 151t - 16t²

The height of the ball when it return to the ground will be 0
0 = 151t - 16t²

The zero product property is that when two numbers are being multiplied and the product is 0, one of them must be equal to 0. Therefore, we can factorize this equation:
16t² - 151t = 0
t(16t - 151t) = 0
By the zero product property:
t = 0   or  16t - 151 = 0

So t = 0 or t = 9.44 seconds

The first solution is before he releases the ball and the second is when the ball comes back to the ground. Thus, the ball's air time is 9.44 seconds.
