Check out the image attachment for one way to draw this problem out. Notice how angles AEC and DEB are vertical angles, so that means they are congruent angles
(measure of angle AEC) = (measure of angle DEB)
6x + 20 = 10x
6x + 20-6x = 10x-6x ... subtract 6x from both sides
20 = 4x
4x = 20
4x/4 = 20/4 ... divide both sides by 4
x = 5
The value of x is 5.
Let's check the answer
6x + 20 = 10x
6*5 + 20 = 10*5 ... replace every x with 5
30+20 = 50
50 = 50
We have confirmed the answer.
Answer:
(-1, 2)
Step-by-step explanation:
Constant of proportionality?
I can find the rate of change
ok, so find first hose rate of change
gallons/minue=318/58=159gal/29min
y=159/29x for first hose
2nd hose
50% faster
times 3/2
477/58=2nd hose
constant of poroprotinality
y=kx
assuming y=amount and x is the time
add the rates
159/29+477/58=795/58=13.7
so the new one would be
y=13.7x
constant is 13.7
C
Answer: 5/12
Step-by-step explanation:
because the denominators are not the same you have to multiply to get a common base and then you can subtract from there to see how much he has left.
Answer:
<em>29.2 and 60.8 </em>
Step-by-step explanation:
x° + x° + 31.6° = 90°
2x + 31.6 = 90
2x = 58.4
x° = 29.2°
90° - 29.2° = 60.8°
<em>29.2</em><em> and </em><em>60.8</em><em> </em>
