i think its twenty hours.....but dont take my word on it im not 100% on it
Answer
41/12
Step-by-step explanation:
convert mixed numbers into improper fractions 21/4-(3-7/6)
calculate 21/4 - 11/6
subtract fractions 41/12
3y^-4 × (2y^-4) = 6y^-8
= 6/1/y^8
= 6/y^8
.................................................
1) When x^1 multiply with x^2, 1 will add to 2 and become 3
= x^3
2) y^-1 = 1/y
3^-2 = 1/3^2 = 1/9
5^-2 = 1/5^2 = 1/25
Answer:
3/5
Step-by-step explanation:
1/10+1/20=3/5
