Order of operation with Integers
vovikov84 [41]

Answer:

8

Step-by-step explanation:

<em>we have to follow PEDMAS.</em>

<u>what we have to do in each operation:</u>

Parenthesis ~  100 + 8 to the second power

Exponents ~ 10 to the 2nd power, 8 to the 2nd power, 2 to the 3rd power

Multiplication  ~  none

Division ~  10 to the 2nd power - (100 + 8 to the second power) divided by 2 to the 3rd power

Addition ~ 100 + 8 to the 2nd power

Subtraction ~ 10 to the 2nd power - (100+8 to the second power)

<u>doing the work:</u>

we start with P: but in what we have to do in the Parenthesis, there is an exponent and addition. we do the exponent first. 8 to the second power is 64. now we can add. 100 + 64 = 164.

E: we did the 2nd exponent, but we need the other 2 for later. 10 to the 2nd power is 100, and 2 to the 3rd power is 8.

we can skip M because there isn't any multiplication to do.

D: we have to do 10 to the 2nd power - (100 + 8 to the second power) first. 100-164= 64. now we can devide. 64 devided by 8 = 8

A: we already did the addition in the parenthesis part.

S: we already did the addition in the parenthesis part.

Radda [10]

Answer:

Yes, you can use this inequality to find the numbers of cars required.

Step-by-step explanation:

12  + 3n > 28     where n = the number of cars required

3n > 28 -12

3n > 16

n > 5 1/3

Greater than 5 1/3 gives 6 cars.

\sf{\red{ANSWER \: \: :}}

x = 18 1/3

\sf{\purple{EXPLANATION \: \: :}}

x - 20 + 2x = 35

- 20 + 3x = 35

3x = 35 + 20

3x = 55

x = 55/3

x = 18 1/3
