What are the numbers so I can do the problem.

Answer:

y = 4

Step-by-step explanation:

I forgot what its called, but you see the 4 on the right side and then how it shows 8 below it? its basically # times 4 for each thing. (1 x 4 = 4) (2 x 4 = 8) (3 x 4 = 12)

Answer:slope is 2 or 2/1 whichever way you choose to write it, it’s the same thing

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

Step-by-step explanation:

Answer:9

Step-by-step explanation:

You said that the areas is one side multiplied by 2. If one side (S) is 3, then 3 x 3 = 9.

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:

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:

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:

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)

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
