P: Parenthesis
E: Equation 
M:Multiplication 
D: Division 
A : addition 
S: Subtraction

So first you need to divide because it is before so you divide 18 by 6 which is 3 then you subtract (31 - 3) which gives you 28

The sum of two numbers is 22. The difference is 6. What are the two numbers?
algol [13]

Answer:

Numbers are 14 and 8

Step-by-step explanation:

Let the 2 numbers be x and y.

Write 2 equations:

x + y = 22

x - y = 6

Solve by substitution:

x - y = 6

x = y + 6

Plug into the other equation:

(y + 6) + y = 22

2y + 6 = 22

2y = 16

y = 8

Plug into either equation:

x + 8 = 22

x = 14

Numbers are 14 and 8

21.) A rectangle has an area of 36 square units. As the length and width change, what do you know about their
natima [27]

Answer:

the length and the width are inversely proportional to each other (l=\frac{36}{w} or w=\frac{36}{l})

Step-by-step explanation:

Let

l units = length of the rectangle,

w units = width of the rectangle.

The area of the rectangle is

\text{Area}=\text{Length}\cdot \text{Width}

A rectangle has an area of 36 square units, so

l\cdot w=36

Complete the table with some values of l and w that fit the previous formula:

\begin{array}{ccc}\text{Length}&\text{Width}&\text{Area}\\ \\36&1&36\cdot 1=36\ un^2.\\18&2&18\cdot 2=36 \ un^2.\\12&3&12\cdot 3=36\ un^2.\\ 9&4&9\cdot 4=36\ un^2.\\l&w&l\cdot w=36 \ un^2.\end{array}

As you can see, the length and the width are inversely proportional to each other (l=\frac{36}{w} or w=\frac{36}{l})

Crazy boy [7]

Answer:

106.81

Step-by-step explanation:

first convert diameter to radius

  • radius = diameter / 2
  • radius = 34/2 = 17

now find circumference

  • circumference = 2πr
  • circumference = 2π(17) = 106.81

r = radius

Is this correct? <br><br> #2 <br><br> Please check
julsineya [31]
Yes you are correct!

you first have to get rid of the number next to the variable m. so you have to subtract 9 to get rid of the variable. then you subtract 9 from both sides and get that answer.
