R+4.6+9=3r-11.7-7r
combine all like terms on one side of the equal sign
r+4.6-4.6+9=3r-11.7-7r-4.6
r+9-9=3r-11.7-7r-4.6-9
r-3r=3r-3r-11.7-7r-4.6-9
r-3r+7r=-11.7-4.6-9-7r+7r
r-3r+7r=-11.7-4.6-9
add them all into one term on each:
5r=-25.3
divide by 5 on both sides:
r= -5.06
Hello there ^ _ ^
2x² = 200
We need to start by dividing both sides by 2
2x²/2 = 200/2
x² = 100
Now we can take square root.
x = +/-√100
x = 10 or x = -10
I hope this help!
Answer:
Surface Area = 6.28 x 5.223 x 3 + 6.28 x 10.446 = 164 cm^2
Step-by-step explanation:
A=2πrh+2πr2
When we divide 245 by 1.5 we find 164cm^2
18/6 = 3 dollars per gallon
8 x 3 = 24
8 gallons would cost $24
answer is C
