Match the expressions given in words with their values when m=6.

Gemiola [76]

Answer:

Value of expression 1 = 3

Value of expression 2 = 42

Value of expression 3 = 15

Value of expression 4 = 2

Step-by-step explanation:

Expression 1 : the sum of m and 3 divided by the difference of m minus 3

Expression 1 $: \frac{m+3}{m-3}$

Substitute m = 6

So, value of expression 1= $\frac{6+3}{6-3}=3$

Expression 2 : the sum of 3 times m and 4 times m

Expression 2: 3m+4m

Substitute m = 6

So, value of expression 2=3m+4m=3(6)+4(6)=42

Expression 3 : the difference of the product of 3 and m minus the quotient of m divided by 2

Expression 3: $3m-\frac{m}{2}$

Substitute m = 6

So, value of expression 2= $3m-\frac{m}{2}=3(6)-\frac{6}{2}=15$

Expression 4 :the quotient of 6 divided by the difference of m minus 3

Expression 4: $\frac{6}{m-3}$

Substitute m = 6

So, value of expression 4= $\frac{6}{m-3}=\frac{6}{6-3}=2$

A plane has 360 total seats which are divided into economy class and business class for every 13 seats in economy class there ar

Marta_Voda [28]

Answer:

There are 260 seats in economy class and 100 seats in business class

Step-by-step explanation:

To solve this problem we first have to calculate the fraction of economic and business seats with respect to the total

We are told that every 13 seats in economy class there are 5 seats in business class

13 + 5 = 18

This means that if there are 18 seats 13 will be economic and 5 business

economic seats = 13/18

business seats = 5/18

To find out the number of seats in the airplane of each class, we have to multiply the total number of seats by these fractions

economic seats = 360 * 13/18

economic seats = 260

business seats = 360 * 5/18

business seats = 100

Help me with this please

Nostrana [21]

Check out the image attachment for one way to draw this problem out. Notice how angles AEC and DEB are vertical angles, so that means they are congruent angles

(measure of angle AEC) = (measure of angle DEB)
6x + 20 = 10x
6x + 20-6x = 10x-6x ... subtract 6x from both sides
20 = 4x
4x = 20
4x/4 = 20/4 ... divide both sides by 4
x = 5

The value of x is 5.

Let's check the answer
6x + 20 = 10x
6*5 + 20 = 10*5 ... replace every x with 5
30+20 = 50
50 = 50
We have confirmed the answer.
