Answer:
12:07pm
Step-by-step explanation:
first common multiple of 60 and 70 is 420
420 s = 7 mins
1. ratio to you and then your friend is 4 : 3. By guessing is the quickest choice and when I did that I finally found that you have had to multiply both by 8 to find:
your allowance : 32
your friend's allowance : 24
32 + 24 = 56
2. ratio to you and then your friend is 7 : 5. By guessin is the quickest choice and when I did I finally found that you have had to multiply both by 6 to find:
your allowance : 42
your friend's allowance : 30
42 + 30 = 72
The probability of the sum of 5 is 5/20 or 1/4.
Solution:
Formula: P(A) = No. of favorable outcomes / Total no. of possible outcomes
P(A) = 5/20
P(A) = 1/4
In order to find the expression that is equivalent to (t*s)(x), use the following steps:
s(x) = x - 7t(x) = 4x^2 - x + 3
(t*s)(x) = t(s(x)) = t(x - 7) = 4(x - 7)^2 - (x - 7) + 3 = 4(x - 7)^2 - x + 7 + 3
The correct result would be 4(x – 7)2 – (x – 7) + 3.
-9 + 5c + 18 - c = 37
4c + 9 = 37
4c = 37 - 9
4c = 28
4c/4 = 28/4
c = 7
hope this helps
