Answer:

Step-by-step explanation:
First let's find the value of 'p-q':

To find |p-q| (module of 'p-q'), we can use the formula:

Where 'a' is the coefficient of 'i' and 'b' is the coefficient of 'j'
So we have:

Now, we need to find the module of p and the module of q:

Then, evaluating |p-q|-{|p|-|q|}, we have:

Answer:
$12,087,912.1
Step-by-step explanation:
is in scientific notation, to get this into normal number, we take the decimal point and move it "9" times to the right [whatever power of 10 we have, we move to right (if positive).] Then we fillup the rest with zeros.
So we have:

This is the revenue.
We do similar process for time:

This is the time , in minutes.
We want revenue PER minute, that means we divide the total revenue by total time, that would be:

The revenue earned per minute is $12,087,912.1
Answer:
21kg
Step-by-step explanation:
We will do this.
11x - 12 = 7x
11x - 4x = 7x
4x = 12
4x/4 = 12/4
x = 3
3 x 7 = 21
Laura weighs 21 kg.
Answer:
10x+4b+3
Step-by-step explanation:
x+x+x+x+x+x+x+x+x+x+b+b+b+b+3
There are 10 x
4 b
and one number
10x+4b+3
Answer:
118°
Step-by-step explanation:
the angle measures of a triangle will always add up to 180
so..
42+20=62
180-62=118
