Um.. Is this a question ?
Answer:
The sum of the internal ángles = 360°
(3y+40)° and (3x-70°) are suplementary angles = 180°
then:
(3x-70) + (3y+40) + 120 + x = 360 ⇒ first eq.
(3y+40) + (3x-70) = 180 ⇒ second eq
development:
from the first eq.
3x + x + 3y = 360 + 70 - 40 - 120
4x + 3y = 430 - 160
4x + 3y = 270 ⇒ third eq.
3y = 270 - 4x
y = (270 - 4x) / 3 ⇒ fourth eq.
from the secon eq.:
3y + 3x = 180 + 70 - 40
3y + 3x = 250 - 40
3y + 3x = 210 ⇒ fifth eq.
multiply by -1 the fifth eq and sum with the third eq.
-3y - 3x = -210 ⇒ (fifth eq. *-1)
3y + 4x = 270
⇒ 0 + x = 60
x = 60°
from the fourth eq.
y = (270-4x)/3
y = (270-(4*60)) / 3
y = (270 - 240) / 3
y = 30/3
y = 10°
Probe:
from the first eq.
(3x-70) + (3y+40) + 120 + x = 360
3*60 - 70 + 3*10 + 40 + 120 + 60 = 360
180 - 70 + 30 + 40 + 120 + 60 = 360
180 + 30 + 40 + 120 + 60 - 70 = 360
430 - 70 = 360
Answer:
y = 10
Answer:
c=12
Step-by-step explanation:
12c - 53= 91
12c=144
c=12
Ok so to simplify 32^3/5, you will need to know the steps, so I'll tell u the step by step solution. ;D
So Step 1: You have to <span>Raise 32 to the 3rd power:
</span><span><span>1.1 </span> 32 = 2</span>⁵
(32)³ = (2⁵)³ = 2¹⁵
<span>the equation has ended on step 1, so now is:
</span><span> 2</span>¹⁵
<span>------
5
</span>
Now step 2:
Simplify it
(you can't simplify this equation but these is the steps you gotta do on other equations so I'm just giving an example.)
2¹⁵
------
5
So basically your final result is:
2¹⁵
------
5

Hope you understand it :D

Answer:
55998000
Step-by-step explanation:
When you take 5 time 3 you get 15
Then you take 15 and times that by 17 and get 225
then you take that and multiply that to 200 and get 5100
Finally you multiply 5100 to 1098 and get 5598000
