Answer:
x = -12
Step-by-step explanation:
Remember that ax + bx = (a+b)x
-10x + 9x = 12
Add -10x and 9x together
(-10 + 9)x = 12
-x = 12 (-1x is written as -x, just as 1x is written as x)
÷ -1 both sides
x = -12
I hope this helps. Happy studying. :)
divide total miles by speed
125/65 = 1.923 hours
there are 60 minutes per hour

Answer:
θ = 280°
Step-by-step explanation:
We assume your intended equation is ...
θ = 14π/9 . . . . radians
π radians is 180°, so we can simply put 180° where π is in your equation.
θ = 14(180°)/9
θ = 280°
All items are 40% off, so their new price is 60% of the old price.
60% = .6
120*.6= $72
To convert 115.9% to decimal divide by 100
115.9 ÷ 100 = 1.159
Answer: 1.159
