I hope this helps you
small circle area=3,14.19^2=1133,5
large circle area =3,14.24^2=1808,6
shaded area=1808,6-1133,5
shaded area=675,1
3x + 4y = 38 ( equation 1) ----> ×5
5x - 5y = -30 ( equation 2) ----> ×3
When you multiply eqn 1 by 5 you get, 15x + 20y = 190
And when you multiply eqn 2 by 3, you get, 15x - 15y = -90
Then you solve both equations by subtracting eqn 2 from eqn 1
15x + 20y = 190
15x - 15y = 90
Then 15x - 15x gets cancelled and 20y - (-15y) gives 35y and 190 - (-90) gives 280.
So that gives 35y = 280
y = 8
And when you replace y = 8 in any of the two equations, x = 2
Answer:
y = 6x - 14

I guess you wanted me to write in slope-intercept form
can i have a brainlest plz
Answer:1.) m∠A +m∠B +m∠C = (sum of angles in a triangle △)
2.) 24° + x + m∠C = 180°
3.) x = 156° - m∠C
Step-by-step explanation:
1. m∠A +m∠B +m∠C = (sum of angles in a triangle △)
2. 28°+x−4° + ______ = 180°
24° + x + m∠C = 180°
3) x = 180° - 24° - m∠C
x = 156° - m∠C
