Answer:
19.6
Step-by-step explanation:
The ratio of brown paint to white paint is, 5:7 or
so if he bought 14 gallons of white paint we need to figure out:

which we can as it only has one unknown:
5x=14×7
5x=98
x=19.6
So the answer is 19.6
I think x= -7 but I'm not to sure
3x + (x+3) = 19
4x + 3 = 19
4x = 16
x = 4
y= x+3
y= 4+3
y= 7
Given:
In circle O, m∠R = 30.8°.
To find:
The m∠NOQ
Solution:
Central angle theorem: According to this theorem, the central angle is always twice of subtended angle on the same arc.
Angle NOQ and angle NRQ are on the same arc but ∠NOQ is the central angle and ∠NRQ is the subtended angle on the arc NQ.
Using central angle theorem, we get




Therefore,
.
