Ex.


(4 x 4) + (4 x 2) = 24
   16    +     8


So, how did I know how to add these two? Well, using PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction) we know whatever's in the parenthesis is what we do first. Since we have to sets of multiplication problems in parenthesis, we can solve either one first, but still regarding the rule of PEMDAS. Make notice of the + sign (bold) in between the two parenthesis. This tell me I will add the two products and get my final answer. But let's say it were the be subtraction oppose to addition.

Ex.

(4 x 4) - (4 x 2) = 8
   16    -    8

Using PEMDAS, I did the parenthesis first. I knew to subtract because of the - sign in the equation, leading to my difference.

Determine the inequality that can be used to model when the population of bacteria will be greater than or equal to 656,100. The
jenyasd209 [6]

The inequality is 100*3^{t}≤ 656100.

The correct option is (B).

<h3>What is inequality?</h3>

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given:

From the table attached below:

a=300, r= 900/300 = 3

As, it is GP

Now,

f(t) = ar^{t-1}

f(t) = 300*3^{t-1}

f(t) = 300/3 *3^{t}

f(t) = 100*3^{t}

Inequality is used to determine greater than or equal to 656100

100*3^{t}≤ 656100

1. You are given PR and RS, so simply add the two measurements to get PS.

28.2+30.7= 58.9

2. Subtract QV from QT to get TV. 

78-56= 22

3. Again, Subtract QV from QT to get TV.

74-36= 38

4. Similar to question 1, add PR and RS to get PS. 

40+53= 93
