Answer:The answer would be 20 books divide 15 \ 1.50 equals 10 then multiply 10 by 2

Step-by-step explanation:

The number of books sold by Holly and Ethan to get a profit of $30 will be 20.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Holly and Ethan decide to sell some of their books at a flea market. The booth rental costs $15, and they will sell each book for $1.50.

The number of books will be calculated as,

1.5x = 30

x = 30 / 1.5

x = 20

Therefore, the number of books sold by Holly and Ethan to get a profit of $30 will be 20.

Answer:

m

Step-by-step explanation:

m=slope

b=y intercept

The symbol m is represent the slop of the line. the correct option is b.

Given that:

Equation: y = mx + b

Since the linear equation show by the formula: y = mx + b

Where,

the letter m represents the slope of the line. The slope m determines the rate of change of the dependent variable y with respect to the independent variable x in a straight-line equation. It indicates how steep the line is and whether it rises or falls as the value of x changes.

Hence, m is the slop of the given equation y = mx + c. The correct option is b.

Answer:

x = 2 and y = -1

Step-by-step explanation:

y = -3x + 5

y = -2x + 3

-3x + 5 = -2x + 3

Add 2x to both sides;

-x + 5 = 3

Subtract 5 from both sides;

-x = -2

Divide both sides by -1

x = 2

Solve for y;

y = -3x + 5

y = -3(2) + 5

y = -6 + 5

y = -1

You got this I believe in you!!

Answer:  False

Step-by-step explanation:

In math formulas, we want to use different symbols to represent different things.

While in linguistics, A and a represent the same thing, the symbols are different, then we can use them to represent different things.

For example, we can define a square of side length a.

And the area of that square will be equal to the square of its side length, we can represent the area with A, such that:

A = a^2.

Here A and a are different numbers (and also represent different measures, a is in units of length and A is in units of surface).

Then the statement is false.

Answer:

−2(−9x+5)−4x=2(x−5)−4

Step 1: Simplify both sides of the equation.

−2(−9x+5)−4x=2(x−5)−4

(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)

18x+−10+−4x=2x+−10+−4

(18x+−4x)+(−10)=(2x)+(−10+−4)(Combine Like Terms)

14x+−10=2x+−14

14x−10=2x−14

Step 2: Subtract 2x from both sides.

14x−10−2x=2x−14−2x

12x−10=−14

Step 3: Add 10 to both sides.

12x−10+10=−14+10

12x=−4

Step 4: Divide both sides by 12.

Step-by-step explanation:

Answer:

The length of AB is 20 units

Step-by-step explanation:

The given parameters from the graph for coordinates A and B are;

The coordinates of the point A = (1, 4)

The coordinates of the point B = (4, 8)

The length of segment AB is given by the equation for finding the distance, d between two points given their coordinates as follows;

[tex]d = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

Where;

(x₁, y₁) = (1, 4)

(x₂, y₂) = (4, 8)

Substituting gives;

[tex]d_{AB} = \sqrt{\left (8-4 \right )^{2}+\left (4-1 \right )^{2}} = \sqrt{25} = 5[/tex]

The length of [tex]\overline {AB}[/tex] = 5

Therefore, given that ΔA'B'C is created by dilating ΔABC by a scale factor of 4, the length of A'B' = 4 × The length of AB

Therefore, the length of [tex]\overline {A'B'}[/tex] = 4 × The length of [tex]\overline {AB}[/tex] = 4 × 5 = 20

The length of [tex]\overline {A'B'}[/tex] = 20 units.

Step-by-step explanation:

Explanation: A diagonal of a rectangle cuts the rectangle into 2 right triangles with sides equal to the sides of the rectangle and with a hypotenuse that is the diagonal. All you need to do is use the pythagorean theorem: where a and b are the sides of the rectangle and c is the length of the diagonal.

The angle that a diagonal makes with a longer side of the rectangle is 38°.

The angle that a diagonal makes with a longer side of the rectangle is (x/2)°.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

a)

The diagonals of a rectangle intersect at 76°.

This means,

From the figure Triangle AOB.

AOB + OAB + OBA = 180

(180 - 76) + x + x = 180

2x = 180 - 180 + 76

2x = 76

x = 38

This means,

The angle with the longer side of the rectangle is 38.

b)

Similarly,

The diagonals of a rectangle intersect at xº.

This means,

AOB + OAB + OBA = 180

(180 - x) + y + y = 180

2y = 180 - 180 + x

2y = x

y = x/2

This means,

The angle with the longer side of the rectangle is x/2.

Thus,

The angle with the longer side of the rectangle is 38°.

The angle with the longer side of the rectangle is (x/2)°.

Answer:

2 and 4

Step-by-step explanation:

To find the answer to "What two numbers have a product of 8 and a sum of 6?" we first state what we know. We are looking for x and y and we know that x • y = 8 and x + y = 6.

Before we keep going, it is important to know that x • y is the same as y • x and x + y is the same as y + x. The two variables are interchangeable. Which means that when we create one equation to solve the problem, we will have two answers.

To solve the problem, we take x + y = 6 and solve it for y to get y = 6 - x. Then, we replace y in x • y = 8 with 6 - x to get this:

x • (6 - x) = 8

Like we said above, the x and y are interchangeable, therefore the x in the equation above could also be y. The bottom line is that when we solved the equation we got two answers which are the two numbers that have a product of 8 and a sum of 6. The numbers are:

Answer: 4 days (I think)

Step-by-step explanation:

One cat = 150*2 = 300g

Two cats = 600g

600*2 = 1200 (this is the total amount of food they both eat in a day)

5kg = 5000g

1200g/5000g = 4.17

The bag will last 4 days.

Step-by-step explanation:

y= mx + b

m= -5/4 (rise over run/slope)

b= 6 (y-intercept)

-I hope this helps have a great day!

Answer:

y = -5/4(x)+6

Step-by-step explanation:

to find the equation of this line, we must first find the slope

We can write the equation of this line y = mx + b where m is the slope and b is the y-intercept

m = (y2-y1)/(x2-x1)

m = (-4-6)/(8-0)

m = -10/8

m = -5/4

b is the y intercept which is at 6

So the equation of the line is y = -5/4(x)+6
