Answer:
15
Step-by-step explanation:
Angle c is 180 - 146 = 34
All 3 angles add to 180:
(5y + 3) + (4y + 8) + 34 = 180
9y + 45 = 180
9y = 135
y = 15
Yes it’s right for this problem
Answer:
about 20
Step-by-step explanation:
The numbers round to 600/30 = 20, which is a reasonable estimate.
You can refine this by doing the next step of long division:
29×20 = 580
Subtracting this from 591.3 give 11.3, so the fraction is ...
11.3/29 ≈ 10/30 = 1/3
A better estimate is 20 1/3.

Answer:
(x -t -250)/2
Step-by-step explanation:
The amount left from x after paying t and 250 is ...
x -t -250
If this is split into two equal parts, each share is ...
share = (x -t -250)/2
