Scientific notation is just a way to simplify a very large and oftentimes complicated number to a smaller one with the exact same value. For example, if I am given the number 1,656,000 to simplify using scientific notation, I would write it out as 1.656 x 10^6
The value at the end is exactly the same as the number I started out with. It is just written differently.
Answer:
<u>3/5</u>
Step-by-step explanation:
= 2/3 + 2/5 - 7/15
= 10/15 + 6/15 - 7/15
= 9/15
= <u>3/5</u>
Answer:
$13.68
Step-by-step explanation:
Assuming they rent for 1 year, the cost is broken down as follows:
Annual renting cost = 22% of 722.98 = 
Usage charge = 3.2% of 159.06 = 
Thus,
Total annual charge = Annual renting cost + Usage charge = 159.06 + 5.09 =164.15
Monthly rental charge would be 164.15 divided by 12 (12 months in 1 year):
dollars
Answer:
convert into slope intercept form by using inverse operations.
Answer:
x^2 +4x = 18
Step-by-step explanation:
The variable y is isolated in the first equation by dividing both sides by the coefficient of y:
3y = 12x . . . . . . given
3y/3 = 12x/3 . . . . . divide by the coefficient of y
y = 4x . . . . . . . simplify
__
This expression (4x) is put in place of y when substitution is used.
x^2 +y = 18 . . . . given
x^2 +4x = 18 . . . . . with 4x substituted for y
