Answer:
X=55°
Y=30°
Step-by-step explanation:
2y=x+5
Y=1/2x+2.5
3y+30=4x-100
3(0.5x+2.5)+30=4x-100
1.5x+7.5+30=4x-100
4x-1.5x=137.5
2.5x=137.5
X=55°
Y=30°
Answer:
34 Euros
Step-by-step explanation:
15% of 40 is 6.
40 minus 6 = 34
4x^2 -28c + 40 = 1
-28c = 1 -4x^2 -40
-28c = -39 -4x^2
c = 39/28 + 4/28x^2
c = 39/28 + 1/7x^2 => answer
4q-4q=8-8
