Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?
The multiplication that takes place while distributing comes before addition and subtraction in order of operations.
In order to combine like terms on one side of the equation, the inverse operation must be used.
When the problem is worked in the correct order, the numbers that Maricella added are not actually like terms.
Maricella did not combine all three constants on both sides of the equation; she combined only two.

Answer:

42 * 10 + 42 * 5

which agrees with the third option (C) shown on the list of possible answers

Step-by-step explanation:

Notice that using distributive property we can write:

42 * 15 = 42 (10 + 5) = 42 * 10 + 42 * 5

which agrees with the third option (C) shown on the list of possible answers.

Line graph

The line graph is the most appropriate.

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.

The relationships between two or more items are frequently represented by the points on a graph.

To monitor changes over both short and long time periods, line graphs are utilized. Line graphs perform better than bar graphs when there are smaller changes. Line graphs can be used to compare changes for multiple groups over the same time period.

Therefore, the line graph is the most appropriate.

Answer:

x = 9

Step-by-step explanation:

The two angles are alternate exterior and has same measurement

15(x+1) = 150 divide both sides by 15

x + 1 = 10 subtract 1 from both sides

x = 9

Answer:

The number of packs is 5.

Step-by-step explanation:

Let the number of juicy packs of gum bought by Marisol be represented by n.

Adeline bought 8 packs of Fun gum with each pack containing 7 pieces of gum.

Total number of gums has Adeline = 8 x 7

                                                          = 56

Total pieces of gum has Marisol = n x 9

                                                      = 9n

Given that Adeline has 11 more pieces of gum than Marisol, thus;

56 = 9n + 11

56 - 11 = 9n

45 = 9n

n = [tex]\frac{45}{9}[/tex]

n =  5

The number packs of juicy gum bought by Adeline is 5 and total pieces of his gum is 45.

Long multiplication is a method of multiplying two numbers which are difficult to multiply easily.

For example, we can easily find the product of 55 × 20 by multiplying 55 by 2 and then adding a 0 at the rightmost place of the answer.

55 × 2 = 110 and 55 × 20 = 1100.

But, many a time finding the product is not this easy. At such times we use the long method of multiplication.

Steps to multiply using Long Multiplication

Multiplying 2-Digit by 2-Digit Numbers

Let us multiply 47 by 63 using the long multiplication method.

1. Write the two numbers one below the other as per the places of their digits. Write the bigger number on top and a multiplication sign on the left. Draw a line below the numbers.

Answer:

The y intercept is 1450

Step-by-step explanation:

Given

[tex]P(g) = -50g + 14590[/tex]

Required

Determine the y intercept

To answer this question, we need to understand the general form of a linear equation.

This is:

[tex]f(x) = mx + b[/tex]

Where b represents the y intercept

By comparing [tex]f(x) = mx + b[/tex] to [tex]P(g) = -50g + 14590[/tex], we have that:

[tex]b = 14590[/tex]

This implies that the y intercept is 1450

Answer:

The answer is

[tex]y = \frac{1}{2} x + 2 \\ [/tex]

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

From the question we have

[tex]y + 2 = \frac{1}{2} (x + 8) \\ y + 2 = \frac{1}{2} x + 4 \\ y = \frac{1}{2} x + 4 - 2[/tex]

We have the final answer as

[tex]y = \frac{1}{2} x + 2 \\ [/tex]
