8 0

Answer:

95

Step-by-step explanation:

let x be his mark in the fourth test, then

mean = \frac{83+81+73+x}{4} = 83 ( multiply both sides by 4 )

83 + 81 + 73 + x = 332

237 + x = 332 ( subtract 237 from both sides )

x = 95

Is 6200 ft greater or less than 1 mile 900 ft
Sphinxa [80]
1 mile is equal to 5280 feet

Add 900 to it:

5280 + 900 = 6180

6180 is less than 6200, so 1 mile and 900 feet is less than 6200 feet.
