A shoe store has 23 pairs off white tennis shoes out of 90 pairs of shoes. Estimate the percent of white tennis shoes

Answer:

n = 4

Step-by-step explanation:

3n + 16 = 7n

Cancel out the 3n by subtracting it from both sides

16 = 4n

Divide both sides by 4 so you are left with n=

4 = n

Answer:

[tex]n=4[/tex]

Step-by-step explanation:

To start off you need to subtract 3n from both sides. That would leave you with:

[tex]16=4n[/tex]

Next, you need to divide both sides by 4, since this equation is equal to [tex]n*4[/tex] and we only want a single n, not multiple. That would give us the answer:

[tex]4=n[/tex]

Answer:

11 6/9

Step-by-step explanation:

Daniel works in a market

He has large bags of potatoes that weighs 26 1/4

Daniel is going to sell them in smaller bags 9/4 pounds each

Therefore the number of smaller bags of potatoes in which Daniel would have filled can be calculated as follows

= 26 1/4 ÷ 9/4

= 105/4 ÷ 9/4

= 105/4 × 4/9

= 105/9

= 11 6/9

Answer:

Two angles are complementary angles if the sum of their measures is 908.

Each angle is the complement of the other. Two angles are supplementary

angles if the sum of their measures is 1808. Each angle is the supplement of

the other.

Complementary angles and supplementary angles can be adjacent angles

or nonadjacent angles. Adjacent angles are two angles that share a common

vertex and side, but have no common interior points.

Answer:

m ≤ - 3

Step-by-step explanation:

Given

- 24 - 6m ≥ 4(m + 1) + 2 ← distribute parenthesis and simplify

- 24 - 6m ≥ 4m + 4 + 2

- 24 - 6m ≥ 4m + 6 ( subtract 4m from both sides )

- 24 - 10m ≥ 6 ( add 24 to both sides )

- 10m ≥ 30

Divide both sides by - 10, reversing the symbol as a result of dividing by a negative quantity.

m ≤ - 3

Answer:

uhhhhhh

m ≤ - 3

Answer:

17 minutes

Step-by-step explanation:

To answer this question, all we have to do is subtract the original amount of money on the phone card by what is remaining after Keiko's call:

20 - 17.28 = 2.72

Now, we divide this number by 0.16:

2.72 / 0.16 = 17

So, Keiko's call lasted 17 minutes

Hope this helps :)

Answer:

x=5

Step-by-step explanation:

4x-3 = 2x+7.​

Subtract 2x from each side

4x-2x-3 = 2x-2x+7.​

2x-3 = 7

Add 3 to each side

2x-3+3 = 7+3

2x= 10

Divide by 2

2x/2 = 10/2

x = 5

Answer:

x=5

Step-by-step explanation:

4x -3 = 2x +7

Let's start by getting the 2x away from the seven. Subtract the 2x from itself and from 4x. We will subtract 2 because a negative will cancel out the positive.

2x -3 = +7

Now let's get the -3 away from 2x. Add 3 to the -3 and the +7. We will add because a positive will cancel out the negative.

2x = +10

Then divide +10 by 2 to get the final answer.

Answer:

  multiply the magnitudes of the numbers; affix a negative sign.

Step-by-step explanation:

The product of a positive number and a negative number is the negative of the product of their numerical values.

For example, ...

  (2)(-3) = -(2×3) = -6

  (-2)(3) = -(2×3) = -6

Answer:

Whenever you multiply two numbers with different signs, the answer is always NEGATIVE.

Answer:

(i) ³/₄ - 6/8, 9/12, 12/16, 15/20

(ii) ⁴/₅ - 8/10, 12/15, 16/20, 20/25

(iii) ⁶/₇ - 12/14, 18/21, 24/28, 30/35

(iv) ⁴/₆ - 8/12, 12/18, 16/24, 20/30

Step-by-step explanation:

When an answer to a question uses the greater than symbol, that means any number above the number used is a possible answer to the equation. However, when it's just a simple "x = 2", then 2 is the only possible answer to that equation. Think about it as if it were on a graph. In the attached file I have a graph that is displaying the equation "x > 4". The entire shaded area to the right of 4 could be a possible answer.

Hope this helps.

Answer:

167.9166459

Step-by-step explanation:

Answer:

x = 9.

Step-by-step explanation:

The first step I did was replace y with 6.

[tex]2x+3\cdot \:6=36[/tex]

I multiplied 3*6 next.

[tex]2x+18=36[/tex]

Then I subtracted 18 from both sides of the equation.

[tex]2x+18-18=36-18[/tex]

After, I simplified the equation.

2x=18

Divided the both by 2 and then simplified again to get...

[tex]\frac{2x}{2}=\frac{18}{2}[/tex]  

[tex]x=9[/tex]

So [tex]x=9[/tex].

Answer:

m<7 = 95 degrees

Step-by-step explanation:

Angle 1 = 3x + 10

Angle 4 = 4x-15

Because of the verticle angles theorum, Angle 1 and 4 are congruent.

So:

3x+10 = 4x-15

    +15       +15

3x+25 = 4x

-3x         -3x

25 = x

Angle 1 = 3x + 10

But now we know what x is so now its (3 times 25) + 10 which is 85

Angle 1 and 3 are a linear pair so they are supplementary (add up to 180)

180-85=95

So, Angle 3 is 95 degrees

Because of the corresponding Angles postulate, 7 and 3 are congruent

So m<7 = 95 degrees

Answer:

C. 25

Step-by-step explanation:

Lets just first do 5-² = .04

So it will look like this

[tex]\frac{1}{1/25}[/tex] To do this all you have to do is flip 1/25 to 25/1 so that you can multiply instead on divide.

It will look like this

.[tex]\frac{1}{1}*\frac{25}{1}=\frac{25}{1}[/tex] = 25

The algebraic expression to model that "the product of a number and fifteen" is 15x, where x represents the unknown number. The statements A, C, and D are true.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

The algebraic expression to model the unknown number problem "the product of a number and fifteen" is 15x, where x represents the unknown number.

From the given options, the following statements are true:

A. You can replace ‘a number’ with a variable to represent an unknown value.

C. Product means the result of multiplying two numbers.

D. The coefficient is 15.

B. is false because the product means the result of multiplying two numbers, not adding them.

E. is not necessarily true for all cases. The product of a number and a variable can be represented in different ways depending on the context and convention, such as using a dot or parentheses.

Step-by-step explanation:

Hey there!

The point shows the coordinates of (-2,1) and (4,6).

Now, When two points are given on a st.line, we use double point formula.

So, use formula;

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]

Put all values of x and y coordinates.

[tex](y - 1) = \frac{6 - 1}{4 + 2} (x + 2)[/tex]

Simplify it.

[tex](y - 1) = \frac{5}{6} (x + 2)[/tex]

[tex]y = \frac{5}{6} x + 2 \times \frac{5}{6} + 1[/tex]

[tex]y = \frac{5}{6} x + \frac{ 8}{3} [/tex]

Therefore, the equation of a line is y= 5/6x+8/3.

Answer:

56

Step-by-step explanation:

z + 12w when z = 8 and w = 4

~Substitute

8 + 12(4)

~Simplify

8 + 48

~Add

56

Best of Luck!

We are provided with the value of z and w:

We have to find the value of z + 12w.....?

Since we have to find the value of the polynomials for the given values of variables. Plug the given values of z and w in the above question:

➝ z + 12w

➝ 8 + 12(4)

➝ 8 + 48

➝ 56

So, the required value of the polynomial is 56.

Answer:

x < -7 or x > -4

Step-by-step explanation:

Answer: 7 = 2/3 + (-24/6)

Answer:

0.21 and 0.22

Step-by-step explanation:

To find m, we can use the formula y2 - y1 / x2 - x1

x1 = 2

y1 = 50

x2 = 4

y2 = 90

Let's plug these numbers into our formula.

m = 90 - 50 / 4 - 2 = 40/2 = 20

So far our equation looks like: y = 20x + b

Now, let's plug one of the points into our equation.

50 = 20(2) + b

Simplify

50 = 40 + b

Subtract 40 from both sides.

10 = b

The final equation is: y = 20x + 10
