Answer:
7.22
Step-by-step explanation:
3.49+7.50+1.79= 12.78
20.00 -12.78=7.22
we know that
Two angles are supplementary if their sum is equal to
degrees
in this problem we have


so
therefore
<u>the answer is</u>
The two angles are supplementary
Answer:
y = 20x + 280
Step-by-step explanation:
The linear equation that represent your account balance is as follows:
Your friend
y = 25(6) + 250
= 400
And,
You
400 = m(6) + 280
6m = 400 - 280
6m = 120
m = 20
Now the equation of the account balance is
y = 20x + 280
Hence, the linear equation that represent your account balance is y = 20x + 280
The last one
If next month is January, then this month is the last of the year
Hypothesis: next month is January
Conclusion: this month is the last of the year
