Step-by-step explanation:

Jason is not correct because 0.819 is not larger than 0.85. Marco's number is larger.

Answer:

number = - 1

Step-by-step explanation:

let the number be n then twice the number is 2n , so

2n + 4 = n + 3 ( subtract n from both sides )

n + 4 = 3 ( subtract 4 from both sides )

n = - 1

The number is - 1

Answer:

Vertical angles are always equal to one another. In general, we can say that, 2 pairs of vertical angles are formed when two lines intersect.

Step-by-step explanation:

Parallel lines are lines that do not meet at any point in a plane.

Intersecting lines are straight lines that meet or crosses each other at a certain point.

Using profit/cost/revenue concepts, it is found that:

----------------------

----------------------

Question a:

The break even point is the value of x for which the revenue is the same as the cost, that is:

[tex]R(x) = C(x)[/tex]

Thus

[tex]5x = 800 + 3x[/tex]

[tex]2x = 800[/tex]

[tex]x = \frac{800}{2}[/tex]

[tex]x = 400[/tex]

400 cookies must be produced and sold to break even.

----------------------

Question b:

The dollar amount is [tex]R(400)[/tex].

[tex]R(400) = 5(400) = 200[/tex]

The dollar amount coming in and going out is $400.

----------------------

Question c:

Profit is revenue subtracted by cost, thus:

[tex]P(x) = R(x) - C(x)[/tex]

[tex]P(x) = 5x - (800 + 3x)[/tex]

[tex]P(x) = 5x - 800 - 3x[/tex]

[tex]P(x) = 2x - 800[/tex]

The profit function is [tex]P(x) = 2x - 800[/tex]

----------------------

Question d:

The profit earned is P(520), thus:

[tex]P(520) = 2(520) - 800 = 240[/tex]

Kimmie will earn a profit of $240.

Answer:

5 1/4 - 2 2/3 = 31/12 = 2 7/12 = 2.5833333

Step-by-step explanation:

1. Conversion a mixed number 5 1/4 to a improper fraction: 5 1/4 = 5 1/4 = 5 · 4 + 1/4 = 20 + 1/4 = 21/4

To find new numerator:

a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/4 = 20/4

b) Add the answer from previous step 20 to the numerator 1. New numerator is 20 + 1 = 21

c) Write a previous answer (new numerator 21) over the denominator 4.

Five and one quarter is twenty-one quarters

Conversion a mixed number 2 2/3 to a improper fraction: 2 2/3 = 2 2/3 = 2 · 3 + 2/3= 6 + 2/3 = 8/3

To find new numerator:

a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/3 = 6/3

b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8

c) Write a previous answer (new numerator 8) over the denominator 3.

Two and two thirds is eight thirds

Subtract: 21/4 - 8/3 = 21 · 3/4 · 3 - 8 · 4/3 · 4 = 63/12- 32/12 = 63 - 32/12 = 31/12

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 3) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 3 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - twenty-one quarters minus eight thirds = thirty-one twelfths.

Answer:

149

Step-by-step explanation:

Adult ticket = x

Let the student ticket be 2x

2x + x = 447

3x = 447

x = 447/3

x = 149

If the number of student tickets sold was two times the number of adult tickets sold approximately 149 adult tickets were sold for the school play.

Let's assume the number of adult tickets sold as 'x'.

According to the given information, the number of student tickets sold is two times the number of adult tickets sold. So, the number of student tickets sold can be expressed as 2x.

We are also given that the total number of tickets sold is 447. Therefore, we can write the equation:

x + 2x = 447

Combining like terms, we have:

3x = 447

To find the value of x, we divide both sides of the equation by 3:

x = 447 / 3

Using a calculator, we find:

x ≈ 149

Answer: B. -8d⁴ - 10d³ - 3d

Step-by-step explanation:

Given expression

(-7d³ + 5d + 5d² - 6d⁴) - (8d + 5d² + 2d⁴ + 3d³)

Expand parentheses

(REMEMBER to change [+, -] signs when there is a [-] sign in front)

=-7d³ + 5d + 5d² - 6d⁴ - 8d - 5d² - 2d⁴ - 3d³

Put like terms together

=-6d⁴ - 2d⁴ - 7d³ - 3d³ + 5d² - 5d² + 5d - 8d

Combine like terms

=(-6d⁴ - 2d⁴) - (7d³ + 3d³) + (5d² - 5d²) + (5d - 8d)

=-8d⁴ - 10d³ + 0 - 3d

Answer:

10, 11, 12

Step-by-step explanation:

Hi there!

Let x be equal to the smallest integer.

Let x+1 and x+2 be equal to the consecutive integers.

We're given that:

⇒ smallest integer + 2 × middle integer = 20 + largest integer

Construct an equation:

[tex](x)+2(x+1)=20+(x+2)[/tex]

Combine like terms:

[tex](x)+2(x+1)=20+(x+2)\\x+2x+2=20+x+2\\3x+2=22+x\\2x=20\\x=10[/tex]

Therefore, the smallest integer is 10.

This makes the consecutive integers 11 and 12.

Answer: 430-8d

Step-by-step explanation:

you start with 430 dollars and you spend 8 a day. you multiply 8 by the number of days and subtract that from 430.

The algebraic expression that describes the situation is 430 - 8d.

Given,

You have $430 but you are spending $8 each day.

We need to find the algebraic expression that describes this situation where d represents the number of days.

An algebraic expression is an expression which is made up of variables and constants.

Find the algebraic expression.

Total amount = $430

Amount spend each day = $8

Let the number of days be denoted by: d

If $8 is spent daily then 8d represents the amount spent for d days.

Now,

$430 is the amount from which the money has to be spent so,

430 - 8d is the required algebraic expression.

Thus the algebraic expression that describes the situation is 430 - 8d.

Answer: Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5, ... . Negative integers are all the opposites of these whole numbers: -1, -2, -3, -4, -5, …. ... If an integer is greater than zero, we say that its sign is positive. If an integer is less than zero, we say that its sign is negative

so 8 9 10 is positive and -8 -9 -10 is negative

they cancel each other out like 8+-8 = 0 and -8+4=-4

Answer:

Step-by-step explanation:

MO bisects ∠LMN.

⇒ ∠LMO = ∠NMO

⇒ ∠LMN = 2 * ∠LMO

   6x - 28  = 2* (x +34)

  6x - 28 = 2*x + 2*34

 6x - 28  = 2x + 68

Add 28 to both sides

6x = 2x + 68 + 28

6x = 2x + 96

Subtract 2x from  both sides

6x - 2x = 96

  4x      = 96

Divide both sides by 4

x = 96/4

x = 24

∠LMO = x +  34 = 24 + 34 = 58

∠MNO = ∠LMO

∠MNO = 58°
