Answer:
y = 5
Step-by-step explanation:
All angle measures in a triangle add up to 180°.
- This means that 63 + 82 + 7y = 180
<u>Solving for Y:</u>
Step 1: Combine like terms.
Step 2: Subtract 145 from both sides.
Step 3: Divide both sides by 7.
Step 4: Check if solution is correct.
Therefore, y = 5.

Answer:
Terry initially had £390
Step-by-step explanation:
The ratio of the original amount is 3:7
Let the original amount Terry has be t and the original amount Faye has be f
3/7 = t/f
or simply 3f = 7t ••••••(i)
Terry putting 220 means he now has
t + 220
Faye withdrew 300
He now has f-300
These values are equal
t + 220 = f-300
f = t+220+300
f = t + 520 ••••••(ii)
Put ii into i
3(t + 520) = 7t
3t + 1560 = 7t
7t-3t = 1560
4t = 1560
t = 1560/4
t = 390
B = 
isolate 6B by subtracting C from both sides
A - C = 6B ( divide both sides by 6 )
B =
