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: 45?
Step-by-step explanation: because a perfect corner is 90 degrees so if you split that, you will get 45!
It takes about 4 days for the temperature to decrease by 9°F.
An equation is an expression that shows the relationship between two or more variables or numbers.
Let x represent the number of days. Given that the temperature drop decreased by 1 1/2°F each day (- 1 1/2), for it to decrease by 9°F (-9):
-1 1/2 * x = -9
-1.5x = - 9
x = 4 days
It takes about 4 days for the temperature to decrease by 9°F.
