Answer:
Hence, 0.0000087 can be expressed as 
.
Step-by-step explanation:
- Given 0.00000871
- Move the decimal point so that the factor is greater than or equal to 1 but less than 10 .
- Then count n and write no. as product with a power of 10 .
Step 1 of 1
Consider 0.00000871,
8.71
Decimal has moved 6 places to right.
The power will be negative as the original no. is less than 1 .
Answer:
Step-by-step explanation:
I assume you mean simple linear equations, maybe not factoring. Anyhow Ill do a few examples:
1. 2x + 5 = 19
2. 14 - 3x = 23
3. 50x / 5 = 150
1. 2x + 5 = 19
Subtract 5
2x = 14
Divide by 2
x = 7
2. 14 - 3x = 23
Subtract 14 to the other side because we have to isolate the term with x in it
-3x = 9
Divide by -3
x = -3
3. 50x / 5 = 150
Multiply by 5 to isolate the value with x
50x = 750
Divide by 50
x = 15
I dont know if this is what you are looking for but this is general idea of how to solve these types of questions. If you need factoring or help with quadratics then let me know!
Set it up as a ratio. $5.25/5 = $1.05 per notebook
Then solve your equation by multiplying the cost by 3. 3 * $1.05 = $3.15
