Answer:
320
Step-by-step explanation:
80*4
190/5= rate per hour 38
38 (rate per hour)*48 (given hours)= 1824 quarts
38(rate per hour)* 24 (hours in a day)= 912 quarts per day
or
1824(quarts made in two days (48 hours))/2=912 quarts per day
★ QUADRATIC RESOLUTION ★
Roots of the given equation will be imaginary because it's discriminant is less than 0 and hence it'll yield imaginary solutions
D < 0
b² - 4ac < 0
4² - 4 ( 5 ) < 0
16 - 20 < 0
-4 < 0
Hence it's character is stated above

Hello,
Your answers and explanations are below.
6 - 5xy
5 times the product of x and y. The product of x and y means to multiply. That is where we get this: xy. 5 times that product is where we add 5 to it and get this: 5xy.
7 - 4x
We get this because we know he gets $4 an hour. We just do not know how many hours he babysat. The hours is X and we multiply that by 4.
8 - 5.5
Take 8.3 and subtract 2.8 to find x. Once we do that we get 5.5, and that is X.
9 - We can't see the problem. It's cut off
Good Luck,
