Hello There!
x + x + 2 = 44
2x + 2 = 44
- 2 - 2
2x = 42
x = 21.
Numbers are 21, 22 and 23.
Hope This Helps You!
Good Luck :)
The top question is B. 30, because you have to set 7y-30 equal to 4y+60 since both lengths are the same.
Your equation is
0.194*x = 43400,
where x is the unknown total number of registered doctors, which is under the question.
Solve the equation to get the answer:
x = 43400/0.194 = 223711 registered doctors.
I think it is B
hope this helps
