Which equation below and solution for X does the model represent??

A) 2x + 2x = 85, x = 42.50

B) 4 + x = 85, x = 21.25

C) x + x + x + x = 85, x = 21.00

D) 4x = 85, x = 21.25

Answer: x = 2

The property is not a conic section.

Answer:

I'm pretty sure its not proportional, because if you divide 8 and 4  you get a half, however when you divide 100 and 75 you get 1.333333.

Step-by-step explanation:

I'm sorry if this is wrong I haven't done this in a while....

Answer:

they are neither. if they were parallel they would be the same. if they were perpendicular they would be opposite reciprocal. So it is neither

Answer:

x = 9.7

Step-by-step explanation:

2.7x -9 = x +7.5

2.7x - x = 7.5 + 9

1.7x = 16.5

x = 16.5/1.7

x = 9.7

Answer:

x = 9.70588

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

2.7x - 9 = x + 7.5

Step 2: Solve for x

Step 3: Check

Substitute in x into the original equation to verify it's a solution.

Here we see that 17.2059 does indeed equal 17.2059.

∴ x = 9.70588 is a solution of the equation.

Answer:

Undefined.

Step-by-step explanation:

m = y2-y1 / x2-x1

m = 3 - 2 / 1 - 1

m = 1/0, which is undefined.

You can also tell because (1,2) and (1,3) is a vertical line, which means the slope is undefined.

6p^2 + 5p - 6

Explanation

6p^2 - 4p + 9p - 6

6p^2 + (-4p + 9p) - 6

And then you would simplify your answer to that which would get you

6p^2 + 5p - 6

Answer:

You will encounter these area word problems often in math. ... If each tile has a length of 24 inches and a width of 36 inches, how many tiles are needed to fill the classroom? ... Area of classroom = length × width = 20 × 30 = 600 ft2 ... Learn about investing money, budgeting your money, paying taxes, mortgage loans

Step-by-step explanation:

Answer:

$234.00

Step-by-step explanation:

1. Find the area of the length of the classroom (L x W), to get 600ft.

2. Convert the area of 1 tile into feet. (Inches divided by 12)=3 Length & 2 Width, and get the area for 1 tile (L x W)=6

3.Divide size of classroom(Area), by the size of 1 tile (Area)=100, to get how many tiles they need to do the whole classroom.

4. We know that the cost for 1 tile $2.34, so do 2.34 times the amount of tiles they need (100), to get $234.00.

Answer:

14 12 10 8 6 4 2

Step-by-step explanation:

Here,

y=8-2x

if x=-3

y=8-2×-3=8+6=14

if x=-2

y=8-2×-2=8+4=12

if x=-1

y=8-2×-1=8+2=10

if x=0

y=8-2×0=8-0=8

If x=1

y=8-2×1=8-2=6

if x=2

y=8-2×2=8-4=4

Given the graph, we can determine the slope, and use slope formula* to prove it.

Points: (-4, 1) and (-2, -1)

From the graph, the slope of the line is -1, mean the line goes down 1 unit and left 1 unit.

To prove this you can use slope formula*:

[tex]m = \frac{-1 - 1}{-2 + 4} = \frac{-2}{2} = -1[/tex]

*Slope formula: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Answer:

The lesson activity requires students to use up to four fours and any operation to make the numbers from 0 to 100. For example, 4 + 4 + 4 + 4 = 16.

Initially, students will use the more familiar operations, +, −, ×, ÷, along with brackets to create their equations.  For example, (4 × 4 + 4) ÷ 4 = 5. Gradually, finding solutions for the remaining numbers in the list becomes more challenging. Here, it is a good opportunity to introduce some other operations to the students, including √4 = 2 and 4! = 24. In my experience, at least one student in the class will be familiar with the square root operation √n, which will make it easier to introduce. The other operation n!, known as factorial, will be less familiar to students.

n! is the product of all positive integers less than or equal to n; for example, 4! = 4 × 3 × 2 × 1 = 24, or 3! = 3 × 2 × 1 = 6

With the introduction of these two less familiar operations, the number of solutions that students can find to the initial problem increases.

Answer:

[tex]-\frac{1}{6}[/tex]

Step-by-step explanation:

In order to find the answer to this question you must use order of operations and add after finding the common denominator.

[tex]-\frac{1}{2} +(\frac{3}{4} \times\frac{4}{9} )[/tex]

P goes first

[tex]\frac{3}{4} \times\frac{4}{9}[/tex]

Solve:

[tex]3\times4=12[/tex]

[tex]4\times9=36[/tex]

[tex]=\frac{12}{36}[/tex]

Reduce:

[tex]12\div6=2[/tex]

[tex]36\div6=6[/tex]

[tex]2\div2=1[/tex]

[tex]6\div2=3[/tex]

[tex]=\frac{1}{3}[/tex]

[tex]-\frac{1}{2} +\frac{1}{3}=\frac{-1\times3}{2\times3} +\frac{1\times2}{3\times2} =-\frac{1}{6}[/tex]

[tex]=-\frac{1}{6}[/tex]

We multiply 43.99 x 1.07=47.07

Hope this helps:)

Answer:

$47.07

Step-by-step explanation:

$43.99 * 7% ----> $43.00 * 0.07 = 3.0793 = $3.08

$43.99 + $3.08 = $47.07

Answer:

36, 8.5

Step-by-step explanation:

an exponent of two means that you are multiply a number by itself

so in this case you would multiply 6 by itself: 6 x 6

this gets you 36

and 8.5 doesn't change so its just 8.5

Your answer should be

C. -2.625

I think its -58 ? Because its lower, so you'd subtract. -31 - 27 = -58

Answer:

Step-by-step explanation:

You must first know that 1 week = 7days

If Sophie practices the piano 105 minutes in 1 week, this can be expressed as;

105 minutes = 7days

to calculate the total time t that she practices for any number of days, d, we will say;

t minutes = d days.

Solving both expression;

105 minutes = 7days

t minutes = d days.

Cross multiply;

7 * t = 105 * d

7t = 105d

Divide both sides by 7;

7t/7 = 105d/7

t = 15d

Hence a proportional equation for t in terms of d that matches the context is expressed as t = 15d
