Answer:
6n - 2 = 9
Step-by-step explanation:
two less than means to switch it with what comes next. Product means multiply by a number( n ). and then obviously equals is = 9.
What is the first point I cant even see it? but all triangles equal 180 degrees so It's B becuase mg and me are 65 degrees 65+65 equals 130. 130 plus 50 is 180 thus your answer I hope I could help <span>(o^▽^o) <3</span>
Similarities
Adding or subtracting a number from both sides.
Multiplying or dividing both sides by a positive number.
Applying an increasing function to both sides.
Simplifying one or both sides.
Differences
Multiplying or dividing both sides by a negative number changes the direction of an inequality. So we cannot multiply or divide both sides by a variable unless we know that the variable is either always positive or always negative. This is not a concern when solving equalities.
When applying a decreasing function to both sides of an inequality, the direction of the inequality changes.
Swapping both sides of an inequality also changes the direction of an inequality. Again we don't have to worry about this with equalities.
To find how much is in the pull in 11 hours, we can plug 11 in for t
W = 9000 -250(11)
W = 9000 - 2750
W = 6250 gallons
To find how long it will take to empty the pool, we can set the gallons equal to 0
0 = 9000 - 250t
To solve for t, we will first subtract both sides by 9000
-9000 = -250t
We will then divide both sides by -250
t = 36 hours
