Answer:
simplify 36 - 4.5x + 36 to -4.5x + 72
simplify 102 - 7.5x - 60 to -7.5x + 42
add 7.5x to both sides
simplify -4.5x + 72 + 7.5x to 3x + 72
subtract 72 from both sides
simplify 42 - 72 to -30
divide both sides by 3
simplify 30/3 to 10
Answer: x = -10
Answer: 9^2 (81)+8^2(64)=12.04^2(144.97) which rounded/estimated is equal to 145
Answer:
We have been given the equation:
![y=-5x+30](https://tex.z-dn.net/?f=y%3D-5x%2B30)
And x=10
Substitute the given x in the given equation we get:
![y=-5(10)+30](https://tex.z-dn.net/?f=y%3D-5%2810%29%2B30)
![y=-50+30](https://tex.z-dn.net/?f=y%3D-50%2B30)
On simplification we get:
![y=-20](https://tex.z-dn.net/?f=y%3D-20)
Required solution is: x= 10 and y=-20
The solution to the system of equation is those points that satisfy the given system of equations.
