-2/(a+b)
Explanation: you are dividing negative two by the sum of a and b so you would put a+b in parentheses as the denominator and then put -2 as the numerator
It would be A on both questions
First Question
1.99+1.50=3,49
3.49 x 2=6.98
6.98+1.40=8.38
20-8.38=$11.62
Second Question
22.50 x 2=45
45+35.50+7.18=87.68
87.68/2=43.84
I believe the correct response would be B. Real numbers and natural numbers.
10-3(x-4)=5(12-2x)
10-3x+12=60-10x
7x+22=60
Answer is B
