10 quarts, because 2 x 2 = 4 quarts, then 1 gallon = 4 quarts, 4 + 4 = 8, then half of 4 is 2, which 8 + 2 = 10.
Answer: 7 hours
Explanation: We can use the equation 93=9h+30 to represent the problem.
When we solve for h with (93-30)/9, we get 7 hours.
Answer:
23 bby <3
Step-by-step explanation:
Step-by-step explanation:
7/20
=0.35
35%
=35/100
=0.35
Hence, 7/20=35%
4x-3y=17......(1)
5x+4y=60......(2)
Multiply equation (1) by 4 and equation (2) by 3:-
16x - 12y = 68
15x + 12y = 180
Adding these 2 equations:_
31x = 248
x = 248/31 = 8
Now substitute x = 8 in equation (1):-
4(8) - 3y = 17
32-3y = 17
-3y = -15
y = -15/-3 = 5
So solution is x=8,y=5
