The average of 5 numbers is 85 . If 3 of the numbers are 102,96 and 80 respectively, what is the sum of the other 2 numbers ?​

Respuesta :

Answer:

147

Step-by-step explanation:

Multiply the average by the number of values

85*5=425

Find the sum of the 3 values you have

102+96+80=278

Take the sum of the 3 values you have away from the sum of all 5 values

425-278=147

Answer:

the sum of the other 2 numbers = 147

Step-by-step explanation:

(102 + 96 + 80 + x + y)/5 = 85

278 + x + y = 85 × 5

278 + x + y = 425

x + y = 425 - 278

x +  y = 147
