Step-by-step explanation:
2/3 -walnuts
1/6-cranberries
2/3+1/6
common denominator-12
2/3 ·4/4=8/12
1/6 · 2/2= 2/12
8/12+2/12=10/12
10/12=5/6

Answer: Daniel bought 3 apples and 7 bananas.
Step-by-step explanation:
Let x represent the number of apples that Daniel bought.
Let y represent the number of bananas that Daniel bought.
He bought a total of 10 apples and bananas altogether. This means that
x + y = 10
Daniel and his children went into a grocery store and he bought $10.15 worth of apples and bananas. Each apple costs $1.75 and each banana costs $0.70. This means that
1.75x + 0.7y = 10.15 - - - - - - - - - - - 1
Substituting x = 10 - y into equation 1, it becomes
1.75(10 - y) + 0.7y = 10.15
17.5 - 1.75y + 0.7y = 10.15
- 1.75y + 0.7y = 10.15 - 17.5
- 1.05y = - 7.35
y = - 7.35/- 1.05
y = 7
x = 10 - y = 10 - 7
x = 3
X + 25 - 10. 25-10 is 15 so you had 15 after class. You must had 8 sheets of paper because 8+25=33. 33-15 is 18. So, you had 8 sheets of paper before class. Hope this helps!
