X = 1 hr lessons and y = 1/2 hr lessons
x + y = 35......y = 35 - x
40x + 25y = 1115
40x + 25(35 - x) = 1115
40x + 875 - 25x = 1115
40x - 25x = 1115 - 875
15x = 240
x = 240/15
x = 16 <=== there are 16 one-hr lessons
and 19 half-hr lessons

Answer:
it should be 17.9, I don't really know how to explain it I'm sorry-
Answer:
See below
Step-by-step explanation:
4 more than 3: 3 + 4 = 7
5 out of 9: 5/9
the sum of 6 and 8: 6 + 8 = 14
10 less than 14: 14 - 10 = 4
the product of 3 and 4: 3 * 4 = 12
the ratio of 2 to 3: 2/3
10 decreased by 8: 10 - 8 = 2
the quotient of 23 and 25: 23/23
3 increased by 33: 3 + 33 = 36
50% of 32: 50% * 32 = 0.5 * 32 = 16
