Answer:
the total of angle's in traingle is 180
so 85+53+c=180
c=180-138
c=42
Answer:
48
Step-by-step explanation:
18 less than half a number is 6.
So this is the formula:
X/2 - 18 = 6.
You can add 18 to 6.
X/2 = 24.
You can now multiply by 2.
X=48
Answer:
3x - 4
Step-by-step explanation:
-9x + 12
divide by -3
3x + (-4)
3x - 4
-9 ÷ -3 = 3
12 ÷ -3 = -4
Hope this helps!
Have a nice day!

Answer:
1244 Ibf(Pounds force)
Step-by-step explanation:
The formula for Total force on a piston when given the diameter of the bore area =
F = P × π × d²/4
P = 150 lb/sq.In
π = 3.14
d = 3.25 in
Hence,
F = 150 lb/sq.In × 3.14 × 3.25 in /4
= 4974.9375 ÷ 4
= 1243.734375 Ibf(Pounds force)
Approximately = 1244 Ibf(Pounds force)
I feel like I just solved this one. its -1 isn't it?
