Answer:
- 90
Step-by-step explanation:
Evaluate 1*- 5 then the outer one
1*- 5 ( with x = 1 and y = - 5 )
= 1(- 5) + 2(- 5)
= - 5 - 10
= - 15
Then
4*- 15 ( with x = 4 and y = - 15 )
= 4(- 15) + 2(- 15)
= - 60 - 30
= - 90
Answer: 2
Step-by-step explanation:
2/7 + 13/14 = 1 3/14
4/14+13/14 = 17/14
The first one means 85 ÷ 5 = 17
The second one means 39 ÷ 3 = 13
The third one means 82 ÷ 2 = 41
The fourth one means 90 ÷ 6 = 15
The fifth one means 80 ÷ 8 = 10
Store a is 3.125 per orange
store B is 3 Per orange
