Answer: 10 over 69 or 10/69
Step-by-step explanation: convert the expression 5 divided by 34.5 then convert the decimal into a fraction 5÷ 69/2. To divide by a fraction, multiply by the reciprocal of the fraction 5× 2/69. By calculating the product you end up with 10/69
Answer:
1/4
Step-by-step explanation:
6/24 = 1/4
We know that:
3x + 10y = 7
We also know that:
x - 10y = 29
Which means that:
x = 29 + 10y
If, x = 29 + 10y,
3(29 + 10y) + 10y = 7
3*29 + 30y + 10y = 7
3(20+9) + 40y = 7
60 + 27 + 40y = 7
87 + 40y = 7
40y = 7 - 87
40y= -80
y=(-80)/40
y=-2
Answer y=-2.
If y=-2,
x-10(-2)=29
x+20=29
x=29-20
x=9
Let's see if these results are true:
3(9)+10(-2)=7
27-20=7 (Correct)
-----------
9-10(-2)=29
9+20=29 (Correct)
Answer once again:
y=-2
Answer:
1 out of 8
Step-by-step explanation:
If you flip a coin there are eight possible outcomes:
HHH
HHT
HTT
TTT
THH
TTH
THT
HTH
SO the probability of getting all heads is 1 over 8.

Answer:
The population of 75 hours from now would be 40,000.
Step-by-step explanation:
The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.
