Question 1:
Add the following:
(i) 3x and 7x
(ii) −5xy and 9xy
ANSWER:
We have
(i) 3x + 7x = (3 + 7)x = 10x
(ii) -5xy + 9xy = ( -5 + 9)xy = 4xy
Answer:
Step-by-step explanation:
Let 'x' be the usage in kWh. When usage is at or under 800 kWh, the cost function C(x) is given by the base charge of $8 added to the rate of $0.05/kWh multiplied by the consumption 'x', in kWh.
Therefore, for 0 ≤ x ≤ 800, the cost function is:
30 dollars = your food bill at the restaurant
Now, you leave 20% for tip..
20% = .20
Then the sales tax charged for your bill is 6%
6% = .06
How much will you be paying in total?
=> 30 dollars * .06 = 1.8 - is the sales tax that will be added to your bill
=> 30 dollars + 1.8 dollars = 31.8 dollars.
then let's calculate the tip which is 20%
=> 31.8 * 0.20 = 6.36
31.8 + 6.36 = 38.16 dollars or approximately 83 dollars
The answer for the first question is D.
here's why: John goes 60 miles an hour so to go 240 miles is 4, and to 30 miles is 30 minutes. so that would mean it would take him 4.5 hours ( 4 hours and 30 minutes. )
The answer to the second question is C.
here's why: since each of the workers mow at the same speed, there's no need to worry about the 9. now you just need to divide 45 by 10 ( 4.5 ) to see how many lawns he mows in an hour ( 4.5 )
