Answer:
5 11/12
Step-by-step explanation:
2 4/16 = 2 1/4
2 1/4 + 3 2/3 = 9/4 + 11/3
27/12 + 44/12 = 71/12 = 5 11/12
It is the plus minus sign. It means to do the addition and subtraction.
Examples:
10 <span>± 7 = 17 and 3
15 </span><span>± 5 = 20 and 10
100 </span><span>± 90 = 190 and 10
It is generally used to indicate a possibility of two outcomes. A negative or positive outcome.</span>
We have :
s - 39⁰+ s - 9⁰ = s + 29⁰
s + s - s = 29⁰ + 9⁰ + 39⁰
s = 77⁰
Answer: 77⁰
Ok done. Thank to me :>
