Solve by back-calculating for the missing number . . . (58 - 7 - 14 + 3)/(5 × 2) = 4
Answer:
30 seconds
Step-by-step explanation:
→ Work out how many floors it's going to travel
15 - 3 = 12 floors
→ Work out how many meters 12 floors is
12 × 5 = 60 meters
→ Work out how long that will take
60 ÷ 2 = 30 seconds
Answer: 
Step-by-step explanation:
To find the inverse of a function, you want to replace x with y and y with x. Then, you solve for y.
[replace y with x and x with y]
[subtract both sides by 7/2]
[multiply both sides by -2/3]
[distribute]

Now, we have our inverse function.

x = 15°
The angle of a straight line is 180°.
37 + 9x + 8 = 180
9x + 45 = 180
9x = 135
x = 15°
40 minutes because 1/3 is 20 minutes because an hour is 60 minutes
