Abuilding has a total of 60 one-bedroom and two-bedroom apartments. there are twice as many one-bedroom apartments as two-bedroom apartments. how many apartments of each type are in the building? use a system of linear equations to justify your answer.

Number of one bedroom apartment is 40 and two bedroom apartment is 20.

Step-by-step explanation:

Let x be the number of one bedroom apartment

and y  be the number of two bedroom apartment

According to the question,

x + y = 60 (1)

x = 2y (2)

Put value of x from equation (2) in equation (1),

2y + y = 60

3y = 60

y = 20

⇒ x = 2 × y = 2 × 20 = 40

Therefore, Number of one bedroom apartment is 40 and two bedroom apartment is 20.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

your answer is the frist one
