Find the sum.
6(2k – 2) + (7k + 5)

Answer:

B

Step-by-step explanation:

Answer:

12 units

Step-by-step explanation:

3x - 5 + 2x + 1 + 4x = 23

9x - 4 = 23

9x = 27

x = 3

3x - 5 = 3(3) - 5 = 4

2x + 1 = 2(3) + 1 = 7

4x = 4(3) = 12

Answer: 12

Answer

12x+40

Step-by-step explanation:

when distributing, you have to multiply all numbers in the parentheses by the variable outside the parentheses

Answer:

he distributed incorrectly. the correct answer is 12x + 40

Step-by-step explanation:

so you have to multiply 4×3x and 4×10

4×3x=12x

4×10=40

so 12x + 40

Answer:

7) 308 square yards

8) approx. 7.03 square inches

Step-by-step explanation:

7) length times width: 20 * 15 2/5 = 308

8) base times half height: (3 3/4 * 3 3/4) / 2 = 7 1/32 ≈ 7.03

Answer:

31 calls

Step-by-step explanation:

This method of information dissemination forms a tree diagram with a common factor of 2 for each next day.

On Monday, Lori made a call.

By noon on Tuesday (the next day), two calls were made by the initial member.

By noon on Wednesday, four calls would be made by the two members.

By noon on Thursday, eight calls would be made.

By noon on Friday, sixteen calls would be made.

Therefore,

total calls made by Friday afternoon = 1 + 2 + 4 + 8 + 16

                                           = 31

Answer:

15

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

Calculate the distance d using the distance formula

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

with (x₁, y₁ ) = (2, 7) and (x₂, y₂ ) = (- 7, - 5)

d = [tex]\sqrt{(-7-2)^2+(-5-7)^2}[/tex]

   = [tex]\sqrt{(-9)^2+(-12)^2}[/tex]

   = [tex]\sqrt{81+144}[/tex]

   = [tex]\sqrt{225}[/tex]

    = 15

Answer:

Step-by-step explanation:

Midpoint formula:

Substituting values:

Missing endpoint is:

Answer:

B)[tex]\frac{-3}{4}[/tex]

Step-by-step explanation:

We are supposed to find the difference of the fractions

a) [tex]-2\frac{1}{2}-(-1\frac{3}{4})[/tex]

[tex]=\frac{-5}{2}+\frac{7}{4}[/tex]

Using equivalent fraction

[tex]-\frac{5}{2} \times \frac{2}{2} = \frac{-10}{4}\\\Rightarrow \frac{-10}{4}+\frac{7}{4}[/tex]

Plot both fractions on number lines

So Using number line

[tex]\frac{-10}{4}+\frac{7}{4}=\frac{-5}{2}+\frac{7}{4}=\frac{-3}{4}[/tex]

So, Option B is true

Answer:

18 hrs

Step-by-step explanation:

6hrs is 25%, so 6 times 3 is 18, Hope This Helps!

75% of a 24-hour day is 18 hour.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

75% of a 24-hour day

let 75% of 24 hour day be x.

So, 75% of 24 = x

x= 75/100 x 24

x= 3/ 4 x 24

x= 18 hours

Hence, 75% of a 24-hour day is 18 hour.

Step-by-step explanation:

the amount of policies or complaints times the money she would get.

Answer:

4000+200n+50x

Step-by-step explanation:

since we dont know how many policies she will sell or how many complaints she will resolve, they need to be variables. so if

N= amount of policies sold

x= complaints resolved

then it would be 4000+200n+50x

Answer:

X = 6x

Step-by-step explanation:

Simplifying

X + 9 + -0.8x = 5.2x + 17 + -8

Reorder the terms:

9 + X + -0.8x = 5.2x + 17 + -8

Reorder the terms:

9 + X + -0.8x = 17 + -8 + 5.2x

Combine like terms: 17 + -8 = 9

9 + X + -0.8x = 9 + 5.2x

Add '-9' to each side of the equation.

9 + X + -9 + -0.8x = 9 + -9 + 5.2x

Reorder the terms:

9 + -9 + X + -0.8x = 9 + -9 + 5.2x

Combine like terms: 9 + -9 = 0

0 + X + -0.8x = 9 + -9 + 5.2x

X + -0.8x = 9 + -9 + 5.2x

Combine like terms: 9 + -9 = 0

X + -0.8x = 0 + 5.2x

X + -0.8x = 5.2x

Solving

X + -0.8x = 5.2x

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '0.8x' to each side of the equation.

X + -0.8x + 0.8x = 5.2x + 0.8x

Combine like terms: -0.8x + 0.8x = 0.0

X + 0.0 = 5.2x + 0.8x

X = 5.2x + 0.8x

Combine like terms: 5.2x + 0.8x = 6x

X = 6x

Simplifying

X = 6x

Answer:

X=6x
