Which of these equations, when solved, gives a different value of x than the other three? 9.1 = -0.2x + 10 10 = 9.1 + 0.2x 10 – 0.2x = 9.1 9.1 – 10 = 0.2x To prepare for his mountain biking trip, Rhyan bought four tire patches. Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining. Which equations could you use to find the price of one tire patch? Select all that apply. 4x – 1.9 = 22.2 4x – 22.2 = 1.9 4x + 1.9 = 22.2 4x + 22.2 = –1.9 22.2 – 4x = 1.9

Answers

Answer 1

Given:

Different equations are given.

Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.

To find:

The equation which gives a different value of x than the other three.

To find the equations that could you use to find the price of one tire patch.

Solution:

In option A,

[tex]9.1 = -0.2x + 10[/tex]

[tex]0.2x= 10-9.1[/tex]

[tex]0.2x= 0.9[/tex]

Divide both sides by 0.2.

[tex]x=\dfrac{0.9}{0.2}[/tex]

[tex]x=4.5[/tex]

Similarly,

In option B,

[tex]10 = 9.1 + 0.2x[/tex]

[tex]0.9= 0.2x[/tex]

[tex]4.5=x[/tex]

In option C,

[tex]10-0.2x = 9.1[/tex]

[tex]-0.2x = -0.9[/tex]

[tex]x = 4.5[/tex]

In option D,

[tex]9.1 – 10 = 0.2x[/tex]

[tex]-0.9 = 0.2x[/tex]

[tex]-4.5 = x[/tex]

Since option D has difference solution, therefore the correct option is D.

Let price of one tire patch be x.

So, price of 4 tire patches = 4x

Remaining amount in Rhyan's gift card = $1.90

Total amount = $22.20

Price of 4 tire patches + Remaining amount in gift card = Total amount

[tex]4x+1.9=22.2[/tex]

It can be written as

[tex]4x-22.2=-1.9,1.9=22.2-4x,22.2-4x=1.9[/tex]

Therefore, the correct options are C and E.

Answers

Answer:

a=-5, k=31

Step-by-step explanation:

Determine a and k so the given points are on the graph of the function:

(1,11) (2,-14)

[tex]y=a(x+1)^2+k[/tex]

To find the required values, we substitute the points into the equation:

[tex]11=a(1+1)^2+k[/tex]

[tex]-14=a(2+1)^2+k[/tex]

Operating:

[tex]11=a(2)^2+k[/tex]

[tex]-14=a(3)^2+k[/tex]

Simplifying:

[tex]11=4a+k[/tex]

[tex]-14=9a+k[/tex]

Subtract the second equation from the first equation:

[tex]11+14=4a-9a[/tex]

Simplifying:

[tex]25=-5a[/tex]

Solving:

[tex]a=25/(-5)=-5[/tex]

a=-5

Use this equation to find k:

[tex]11=4a+k[/tex]

[tex]11=4(-5)+k[/tex]

[tex]11=-20+k[/tex]

k=31

a=-5, k=31

Answer:

a = -5

k = 31

A librarian wants to spend no more than $800 on some new desks and chairs for the library. The librarian decides to spend $320 on desks.

If each chair costs $24, what is the maximum number of chairs the librarian can buy for the library and stay within the budget?

Answers

Answer:

Step-by-step explanation:

480/24

The maximum number of chairs that the librarian can buy is 20

What are mathematics operations?

A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.

• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.

Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which :

s represents = the number of chairs,

and we simply solve for s.

800 = 320 + 24s  ... subtract both sides by 300

500 = 24s ... divide both sides by 24

20.83 = s

Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.
