4 chairs per table

Step-by-step explanation:

Answer:

4 Chairs Per Table

Step-by-step explanation:

There are 20 tables at 5 tables.

We need to find the number of chairs per person.

Divide 20 by 5.

[tex]\frac{\text{Total Number of Chairs}}{\text{Total number of Tables}} =\frac{20}{5}=\frac{20/5}{5/5}=\frac{4}{1}=\boxed{4}[/tex]

There should be 4 chairs per table.

Hope this helps.

Answer:

m=5

Step-by-step explanation:

There are no fractions involved to eliminate.

2m-3=2+1m

m=5

Based on the given scenario, the solution to the equation 2m - 3 = 2 + 1m is m = 5.

Fractions are a way of representing parts of a whole. They are written in the form of a numerator and a denominator, separated by a horizontal line.

For example, the fraction 3/4 represents three parts of a whole that is divided into four equal parts.

To eliminate the fractions in the equation 2m - 3 = 2 + 1m, we can multiply both sides of the equation by the least common multiple (LCM) of the denominators of the fractions.

However, in this equation, there are no fractions, so we don't need to multiply by anything to eliminate them. The equation is already in a form that can be solved using basic algebraic techniques.

To solve for m, we can start by moving all the m terms to one side of the equation and all the constant terms to the other side:

2m - 1m = 2 + 3

Simplifying, we get:

m = 5

Therefore, the solution to the equation 2m - 3 = 2 + 1m is m = 5.

Answer:

-4

Step-by-step explanation:

Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.

So to solve for x, set 28 and 10x+68 equal to each other.

28=10x+68

First, subtract 68 from both sides

-40=10x

Then, divide both sides by 10

-4=x

If you want to check your answer plug -4 back into the original equation.

28=10(-4)+68

28=-40+68

28=28, which is true, therefore -4 is correct.

Answer:

8 pounds

Step-by-step explanation:

Total ratio = 3 + 1 + 5 = 9

x = total pounds of chicken, beef and fish bought

equation for pounds of fish bought = 5/9 × x = 10

divide both sides by 9/5

x = 18

pounds of chicken bought = 3/9 x 18 = 6 pounds

pounds of beef bought = 1/9 x 18 = 2 pounds

total weight of meat bought = 6 + 2 = 8 pounds

Step-by-step explanation:

xy = k, where k is a real constant.

When y = -1/4, x = -8.

=> k = (-8)(-1/4) = 2.

Therefore when x = 4,

y = k/x = (2)/(4) = 0.5.

In an inverse variation the value of y is 0.5

What is the value of y ?

In an inverse variation, X = -8 wheny= - 1/4.

y= - 1/4.

the value of y when x = 4

In the equation xy = k, k is a real constant.

X equals -8 at y = 1/4.

=> k = (-8)(-1/4) = 2.

Consequently, if x = 4,

y = k/x = (2)/(4) = 0.5.

In an inverse variation the value of y is 0.5.

Answer:

The required number will be:

Step-by-step explanation:

Let 'x' be the number

so

23.2% of x = 34.8

23.2% × x = 34.8

23.2/100 × x = 34.8

0.232x = 34.8

divide both sides by 0.232

0.232x/0.232 = 34.8/0.232

x = 150

Therefore, the required number will be:

Answer:

The slope is 1

Step-by-step explanation:

The line's equation is y=x+3

4-(-1)/1-(-4)=5/5=1. That's the slope.

Answer:

1

Step-by-step explanation:

Use the following equation:

slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

([tex]x_1 , y_1[/tex]) = ([tex]-4 , -1[/tex])

([tex]x_2 , y_2[/tex]) = ([tex]1 , 4[/tex])

Plug in the corresponding numbers to the corresponding variables:
