Solve for m: -8 = m/-10 - 16

Answers

Answer:

m = -80

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

-8 = m/-10 - 16

Step 2: Solve for m

Add 16 to both sides:                    8 = m/-10Multiply -10 on both sides:            -80 = mRewrite:                                          m = -80

Answer:

We have this equation:

-8 = m/-10 -1

We can add 8 at both sides:

-8 + 8 = m/-10 -16 + 8

0 = m/-10 -8

Now, we can multiply -8 by -10 with the objective of having the same denominator (-10) in all numbers:

0 = m/-10 - 8*(-10)/-10

0 = m/-10 +80/-10

Now, we can delete all denominators

0 = m + 80

And we can say m = -80

Now, we can replace it to see if it's true:

-80/-10 - 16 = -8, so we know that's true

-80/-10 -16 = 8 - 16 = -8 ..

The perimeter of a rectangle can be found using the formula 2l + 2w, where l represents the length of the rectangle and w represents the width of the rectangle. Find the perimeter of a rectangular swimming pool whose length is 32 feet and width is 20 feet.

Answers

Answer:

The perimeter is 104

Step-by-step explanation:

The formula for a peremeter is 2 * length + 2 * width.

Substitute the length and width for the given values.

2 * length + 2 * width

2 * 32 + 2 * 20

64 + 40

Tiana compares the length of a name on a nameplate to the number of letters in the name. She draws the scatterplot below, and then she plots and determines an equation for the trend line. Nameplates A graph has letters on the x-axis and length (inches) on the y-axis. A trend line goes through points (2, 5) and (4, 8). The regression equation is y = 1.47 x + 2.05. Based on the information above, which is the best estimate of the number of letters that a name contains if the nameplate is 6 inches long? 3 4 10 12

Answers

Answer:

3

Step-by-step explanation:

The best estimate of the number of letters that a name contains is if the nameplate is 6 inches long will be 3. Option A is correct.

What is a scatter plot?

Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both coordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.

It is given that, the regression equation is y = 1.47 x + 2.05.

The name's letter count is represented by variable x, whereas the name's length on a nameplate is represented by variable y.

The nameplate is 6 inches long, so y=6 and you can find x by doing the following:

6=1.4x+2.05

1.4x=6-2.05

1.4x=3.95

x=2.69

x≈3

Thus, the best estimate of the number of letters that a name contains is if the nameplate is 6 inches long will be 3. Option A is correct.

15 + 15 + 10 + 10 + 10 = 60/5 = 12 ( CODE WORD)

Step-by-step explanation:

1. There are different forms of linear equations. Slope intercept has it's equation y = mx + b

2. A proportional relationship has a constant rate of change.

ex: y =2x +5, then the rate of change is 2 and it only ever rises by 2.

3. A proportional relationship must pass through the origin in order to be a proportional relationship.

4. The variable M in slope-intercept form represents the slope. B represents the Y-intercept.

5. Standard form for a linear equation is Ax+By=C. Y = MX+B is slope-intercept form.
