solving by substitution: t = -9, r = -6
Step-by-step explanation:
Answer:the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 is $15.3
Step-by-step explanation:
Let x represent the number of ccf of water that Jake uses in a month.
Jake's water bill is $24.40 per month plus $2.20 per ccf (hundred cubic feet) of water. This means that if she uses x ccf of water in a month, her total water bill would be
24.40 + 2.2x
Therefore, the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 would be
24.40 + 2.2x ≤ 58
2.2x ≤ 58 - 24.4
2.2x ≤ 33.6
x ≤ 33.6/2.2
x ≤ 15.3
Answer:
The probability of its compliments = 0.7143 = 5/7
Step-by-step explanation:
The probability of an events = P= 2/7 = 0.2857
The probability of its compliments = 1-p = 1-0.2857 = 0.7143 = 5/7
of 
is 
Solution:
Given of what number is .
Let us first convert the mixed fraction into improper fraction.
Now, let us take the unknown number be x.
Do the cross multiplication.
Now, again change the improper fraction into mixed fraction.
Hence of is .
