Answer:
y = (4x - 9) / 5 or y = 4/5x - 9/5
Step-by-step explanation:
Solving for y
4x - 5y = 9
-5y = -4x + 9
5y = 4x - 9
y = (4x - 9) / 5 or y = 4/5x - 9/5

Answer:
x = 2
Step-by-step explanation:
Rewrite the equation as 4x - 6 = 2
Move all terms not containing x to the right side of the equation:
Add 6 to both sides of the equation.
4x = 2 + 6
Add 2 and 6.
4x = 8
Divide each term by 4 and simplify.
Divide each term in 4x = 8 by 4.
Reduce the expression by cancelling the common factors.
Divide 8 by 4.
x = 2
Blue balls : Total number.
Total number of balls = 50 + 45 + 65 = 160
Blue balls : Total number.
= 65: 160 Divide both by 5.
= 13 : 32
= 13/32. That is the ratio.
Multiply 15 x 3.14. You'll get 47.1. Thats the area
