C/5.3+8.3=11.3

lime · Answer

C could stand for Circumference, or a variable among other things. I'll see what I can do. Let's assume C is a variable.

anonymous · Answer

Okay..........

lime · Answer

$$C/(5.3+8.3) = 11.3 $$

lime · Answer

$$C \approx 153.68 $$

anonymous · Answer

Thx. Now I need help with this equation?
35= -5 +2x-7x

lime · Answer

$$35 = -5 + (2x - 7x) $$ Use the substitution method.

lime · Answer

$$35 = -5x - 5$$

anonymous · Answer

35 = -5 + (2x - 7x)
35 + 5 = -5x
40 = -5x
-40/5 = x
-8 = x

lime · Answer

I was too slow. x = -8. Yep. ;)

anonymous · Answer

Who cares if you were slow? You do things systematically and that's great! :)

anonymous · Answer

Lol ya. Thank you. 
Sorry, I need help with this one too.
-1.2= z/4.6-2.7

lime · Answer

Linear equations. I never liked these. $$-1.2 = (z) / (4.6 - 2.7) $$$$z \approx -2.28$$ It's really helpful if you use a linear plane.

anonymous · Answer

-1.2 = z/1.9
-1.2*1.9 = z
-2.28 = z is your final answer.

anonymous · Answer

4d-13+7d=-24

anonymous · Answer

11d - 13 = -24
11d = -24 + 13
11d = -11
d = -1

anonymous · Answer

Okay.
How do you draw on this thing?

$$10 = 2/(7n + 4)$$

lime · Answer

$$10 = 2/(7n+4) $$$$6 = (2/7n)$$$$(7/2)2/7n = (7/2)6  $$$$n = 21 $$
