let "one number" = x, and "another" = y
x = 4y + 4
(x + y) - 4 = 28
Plug in 4y + 4 for x
4y + 4 + y - 4 = 28
Simplify. Combine like terms
5y = 28
Isolate the y. Divide 5 from both sides
y = 28/5
y = 5.6
Plug in 28/5 for y.
x = 4y + 4
x = 4(28/5) + 4
Simplify
x = 22.4 + 4
x = 26.4
x = 26.4, y = 5.6
hope this helps
Answer: 4
Step-by-step explanation:
There are 4 terms,
Prob of picking 9 in 1st turn = 4 / 52
Prob of picking 9 is 2nd turn = 3/51
So Probability for both = 4 * 3 / (52*51)
=1/221
Answer:
60 gallons
Step-by-step explanation:
We can create a ratio for this. If we consider 2 as the 1 in the ratio, we have a ratio of 1 : 2.5. Therefore, we just need to multiply 24 by 2.5, which equals 60.
