Answer:
2400 and 3600
Step-by-step explanation:
Radio 1 cost = x
Radio 2 cost= 6000- x
- x*1.2+(6000-x)*0.9= 6000*1.02
- 1.2x-0.9x+5400=6120
- 0.3x= 6120-5400
- 0.3x= 720
- x=720/0.3
- x= 2400
- 6000- x= 3600
Using the definition of angles on a straight line, the measure of angle BEC is: 62°.
<h3>What are Angles on a Straight Line?</h3>
Angles that lie on a straight line add up to 180 degrees.
Thus, given that EB bisects ∠AEC, therefore:
m∠BEC = 1/2(180 - m∠CED)
Plug in the values
m∠BEC = 1/2(180 - 56)
m∠BEC = 1/2(124)
m∠BEC = 62°
Thus, using the definition of angles on a straight line, the measure of angle BEC is: 62°.

<span>If the tip, t, varies directly with the number of guests, g, then it means that any change in tip there is a corresponding change in the number of guests. When the tip increases the number of guests increases as well. Therefore,
t </span>α g
To change the it to equal sign, we incorporate a proportionality constant, k.
t =<span> kg
</span>
This equation will represent the relation of t to g.
If your 2 means "u squared" then
Just do 8-42=-34
The answer is -32u^2
I use ^ to show exponents
