All the answers to the various operations given from question 1 to 6 have been explained and answered below.
1) We want to use order of operations to solve;
105 - 7² + (72 ÷ 9)
From order of operations which is BODMAS.
First operation for our given expression is bracket. Thus;
72 ÷ 9 = 8
Thus, we now have;
105 - 7² + 8
Next is addition;
7² + 8 = 57
Thus, we now have;
105 - 57 = 48
2) 884284
- 349407
534877
3) 6 ÷ ²/₇
⇒ 6 × ⁷/₂
⇒ 21
4) Kevin makes $78.37 per day. Thus;
Amount he makes in 7 days = 78.37 × 7
⇒ $548.59
5) Product of 1389 and 6.58
⇒ 1389 × 6.58
⇒ 9139.62
6) We want to use distributive property to express 27 + 60.
Now, in distributive property, it implies that;
a(b + c) = ab + ac
Thus, let us get the greatest common factor of 27 and 60 and factorize it out.
GCF of 27 and 60 is 3. Thus;
27 + 60 = ((3*9) + (3*20))
⇒ 3(9 + 20)
⇒ 3(29)
