Answer:
20
Step-by-step explanation:
The question tells us that line a is parallel to line b (even if they don't seem to be in the image).
∠8 = ∠4 and ∠5 = ∠1 since line t crosses the parallel lines.
We are given ∠4 = 3x and ∠5 = 6x.
Since we know ∠8 = ∠4 , we can then say
∠8 = 3x and ∠5 = 6x
Since ∠8 and ∠5 are complementary and combined they form a flat angle of 180 degrees, we can say:
3x + 6x = 180
9x = 180
x = 20
X^2 - 5x = -2x
1. Move -2x to the left
x^2 -5x + 2x = 0
2. Collect like terms
x^2 - 3x = 0
3. Factor out
x(x-3) = 0
4. Separate into possible cases
x = 0 or x = 3
Answer:
She will need to work 11 hours
Step-by-step explanation:
She has $88, and the plane ticket is $308. 308 - 88 is 220, 220 divided by 20 is 11.

Answer:
3.37 times
Step-by-step explanation:
Probability of hitting and odd number= 3/5
Probability of hitting and odd number=2/5
Probability of hitting and odd number three times= (3/5)^3
Probability of hitting and odd number three times=(2/5)^3
Now
(3/5)^3 / (2/5)^3 = 3.37
Hence Probability of hitting an odd number three times is 3.37 times more than the probability of hitting an even number three times !
