43
Explanation:
Since the angle of a triangle is 180°
you first add the given numbers which are 82 and 55 which is 137
then you subtract 137 by 180 since it’s the total number 180-137 is 43
Yes, one of the numbers has to be 48 because the mean of numbers is all the numbers added together, and then divided by how many numbers you added. In this case, we have the mean of 6 number is 48. Now if you think about it,
48*6 = 288
And if you divide 288 by 6, you get:
288/6 = 48.
To make it easier for you to understand, let’s do the original way of finding the mean of this, so :
48 + 48 + 48 + 48 + 48 + 48 = 288
There are six 48’s right? So we divide :
48+48+48+48+48+48
——————————— = 48.

Answer: 11 - 5y
==================================
Working:
5y + 6(3 - y) - 4y - 7
= 5y + 18 - 6y - 4y - 7
= 11 - 5y
You should "open" the brackets before anything else and then start adding and subtracting the ones with the "y" together and the normal numbers together
Answer:
6 1/4 cups
Step-by-step explanation:
I converted the 2 3/4 to 2.75 and 3 1/2 to 3.5, then added 2.75+3.5 to get 6.25 which converts to 6 1/4 cups
