Answer:
ratio of hours lisa works to hours lisa sleeps= 3:8
Step-by-step explanation:
lisa goes to school for 7 hours per day lisa works 3 hours per day
Lisa sleeps 8 hours per day.
For the ratio of hours lisa works to hours lisa sleeps
ratio of hours lisa works to hours lisa sleeps= hours Lisa works/hours Lisa sleeps
ratio of hours lisa works to hours lisa sleeps= 3/8
ratio of hours lisa works to hours lisa sleeps= 3:8
Answer:
The answer to your question is (2,12). Hope you have a nice day.
Step-by-step explanation:
So, first you put in the x value. 8(2)-y=4, 16-y=4. Then you subtracted 4 from each side. 4-4=0 and 16-4=12. 16-12=4.
There are 6*6 total
combinations = 36 combinations.
For A: the probability
that one rolls a 9 is 4/36
<span>(9 = 3&6, 6&3, 4&5, 5&4) </span>
For B: the probability that one rolls a 6 is 5/36
<span>(6 = 3&3, 1&5, 5&1, 2&4, 4&2) </span>
<span>So find the probability that final roll is made by A:
P(A wins) = P(A
wins in first roll) + P(A wins in 3rd roll) + ..... </span>
<span>P(A wins) = 4/36 + (32/36)*(31/36)*(4/36) +
(32/36)^2 *(31/36)^2 *(4/36) + ... </span>
Therefore we see that the common ratio is (32*31/36^2)
Sum is = (4/36) / [1 - (32*31/36^2)]
= 144 / 304
<span>= 9 / 19 (ANSWER)</span>
2v + 18 = 16 - 4(v + 7)
Simplify by removing the parenthesis.
2v + 18 = 16 - 4v - 28
Now, simply add 4v to both sides.
2v + 4v + 18 = 16 - 28
Simplify.
6v + 18 = -12
Now, subtract 18 from both sides.
6v = -12 - 18
Simplify.
6v = -30
Finally, divide both sides by 6.
6v ÷ 6 = 30 ÷ 6
Simplify.
v = 5
