Jamie went to the movies with her twin sister, Jenna. They bought one large soda for $4.95 and 3 boxes of candy. Each box of candy cost the same amount. They spent a total of $18.45. Select the equation that best represents how you would solve for c, the cost of each box of candy?

Answers

Answer 1

Answer:

The Equation we can use to solve for the cost of each box of candy =

4.95 + 3b = 18.45

The cost of each box of candy = $4.5

Step-by-step explanation:

Let the number of boxes of candy be represented by: b

Each box of candy cost the same amount

Hence from the question above, we have the Equation:

$4.95 + 3b = $18.45

4.95 + 3b = 18.45

3b = 18.45 - 4.95

3b = 13.5

b = 13.5/3

b = 4.5

The cost of each box of candy = $4.5

Tina solved an equation incorrectly, as shown below:

Step 1: 8x = 24
Step 2: x = 24 − 8
Step 3: x = 16

Which statement best explains why Step 2 is incorrect in Tina's solution?

Answers

Answer:

Step 2 should be division, not subtraction.

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

8x = 24

Step 2: Solve for x

Divide both sides by 8:                    x = 3

We see that 8x is actually 8 times x. Therefore, we would need to use the Division Property of Equality to isolate x and get our answer.

Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]

Answers

Answer:

The average rate of change on the given interval is 9/70

Step-by-step explanation:

Here, we are to find the average rate of change of the function on the given interval

We proceed as follows;

on an interval [a,b] , we can find the average rate of change using the formula;

f(b) - f(a)/b-a

From the question;

a = 0

b = 3

f(0) = -3/5

f(3) = -3/14

Substituting the values, we have;

-3/14-(-3/5)/3-0

= 3/5-3/14/3

= (42-15)/70/3

= 27/70/3

= 27/70 * 1/3 = 9/70

Is (-8,7), (0,1), (2,-6), (2,3), (7,9) a function?
What’s the domain and range?

Answers

No it is not a function because the 2 repeats and for it to be a function none of the x values can repeat.

The domains are -8, 0, 2, 2, 7 (when it asks for domain it is asking for the x values)

The ranges are 7, 1, -6, 3, 9 (when it asks for range it is asking for the y values)

Suppose x = 9 is a solution to the equation f(x) = g(x). If a table of values for the equation y = f(x) contains an x-value of 9 and a corresponding y-value of 18, then which of these statements is correct about a table of values for the equation y = g(x)?


A
If it contains an x-value of 9, the corresponding y-value must be 9.

B
If it contains an x-value of 9, the corresponding y-value must be 18.

C
If it contains a y-value of 18, the corresponding x-value must be 9.

D
If it contains a y-value of 18, the corresponding x-value must be 18.

Step-by-step explanation:

3x + 2y = 23

2y = 23 - 3x

y = 23/2 - 3/2x

sub into eqn. 2

1/2x - 4 = 23/2 - 3/2x

1/2x + 3/2x = 23/2 + 4/1

2x = 23/2 + 8/2

2x = 31/2

x = 31/4

sub into eqn. 1

31/4 + 2y = 23

2y = 23 - 31/4

2y = 92/4 - 31/4

2y = 61/4

Answer: 26

Step-by-step explanation:

Okay, so... The new equation would be -2(-3)+20...

So follow the rule of PEMDAS, PEMDAS is;

Parentheses

Exponents

Multiplication

Division

Adding

and Subtracting

Since there are no equations in parentheses and no exponents, we start with multiplication. Which would be -2(-3). ANY parenthesized number beside another number means you must multiply them.

-2(-3) = 6 because a negative multiplied by a negative is a positive..

Now we have 6 + 20 which is 26, so 26 is your answer.
