Answer:
Option (2).
Step-by-step explanation:
The given expression is [
]
We can rewrite the fractions as,
= 

Now we will substitute the fractions in the expression,
![[-(5+\frac{1}{4})]-[-(7+\frac{1}{2})]](https://tex.z-dn.net/?f=%5B-%285%2B%5Cfrac%7B1%7D%7B4%7D%29%5D-%5B-%287%2B%5Cfrac%7B1%7D%7B2%7D%29%5D)
= 
= (-5 + 7) + 
= 2 + 
= 2 + 
= 
Therefore, Option (2). will be the answer.
Answer:
Step-by-step explanation:
Given that Mike and Lisa are brother and sister. Mike has as many brothers as sisters, and Lisa has three times as many brothers as sisters
i.e. If Mike has x sisters, then he has x brothers.
i.e. no of sons in total = x+1 (including Mike)
No of daughters = x
Lisa's brothers = x+1 and and Lisa sisters = x-1 (exclusing Lisa)
Given that

Hence we find that there are 3 sons and two daughters in the family.
Answer:
Hey mate, here's your answer. Hope it helps. (^o^)
the shape is NOT a rhombus, because opposite sides are parallel but not all sides are congruent in length.
This shape is instead a parallelogram, where opposite sides are parallel but all sides do not have to be the same length
if 2 pairs of opposite sides are parallel, then opposite sides must be congruent, changing the angles will create nonparallel opposite sides that are unequal length and neither a parallelogram nor rhombus
