Let's say that you go out for dinner. The meal and the service are excellent. You want to leave a really good tip for the waiter

, and you've heard that 20 percent is a really good tip. The total bill for your dinner is $53.82.
Write a paragraph explaining how to quickly estimate that the 20 percent tip rounded to the nearest dollar is $11. Type your answer into a text file.
Math is soooo confusing to me :/

First, to estimate we can round 53.82 up to 55.00. Then you can look at it like this: when you divide 100 by 20 you get 5, so 20% is one fifth of 100. Therefore, we want to find one fifth of $55. To do this, you multiply 55*1/5. When you multiply the numerators by each other and the denominators by each other, you get 55/5. When you divide the numerator and denominator by 5, you get 11/1 or $11.

Hope this helps

Write an equation of the line that passes through the point (4, –5) with slope 2.
Igoryamba
So, the equation is y=mx + b and you want to solve for b to find the y intercept. 
-5=2(4) + b
-5=8+b
subtract the 8 
-13=b
the equation is y = 2x - 13

Solve the system of equations 6x+3y=12 and 5x+y=7
Levart [38]
6x+3y = 12
Solving for x
3(2x+y)=12
2x+y=12/3
2x+y=4
2x=4-y
X=4-y/2
