To solve for the value of y, all you have to do is add up all the expressions and values together and make it equal to 180 degrees.
Y + (Y - 12) + 56 = 180
2Y - 12 + 56 = 180
2Y + 44 = 180
Y = 68 degrees.

Answer:
128
Step-by-step explanation:
Quotient means to divide. So i.e you want to work out 640÷5.
A quick trick to divide by 5 (Without a calculator) is to double the number, and the divide by 10.
so i.e we get 640x2 = 1280.
Then 1280÷10 = 128.
If you would like to solve - 6 1/4 + 2 1/8 - 0.02 + 1/5, you can calculate this using the following steps:
- 6 1/4 + 2 1/8 - 0.02 + 1/5 = - 25/4 + 17/8 - 2/100 + 1/5 = - 50/8 + 17/8 - 1/50 + 10/50 = - 33/8 + 9/50 = - 825/200 + 36/200 = - 789/200 = -3.945
The correct result would be - 789/200.
