The substitution method means you replace the variable in one equation with the other equation, so your new equation is x+4x-8=10. Add 10 to both sides to get 5x=18. Divide both sides by 5 to get x=3.6. This is a weird equation, but then to get y, work backwords. 3.6 times 2=7.2. 7.2-4=3.2 y=3.2. Finally to finish checking solve the equation as normal. 3.6+6.4=10. I hope this helped! Please give brainliest!
Your final answer is x=3.6 y=3.2

Answer:
Step-by-step explanation:
The white area is the area of the circle minus the area of the triangle.
Aw=pr^2-hb/2
Aw=p4^2-6.5(6)/2
Aw=16p-19.5
The probability of selecting the white area is the white area divided by the area of the circle
P(W)=(16p-19.5)/(16p), p=3.14
P(W)=0.61
Answer:
In order to determine the change in percent, I divided 4.02/1.37 to get approximately 2.9. I expressed this as a percent to get 290%.
