It would be 180- 80 which is equal to 100 just remember supplementary is equal to 180
Answer:
gcd(20a,14b)
Step-by-step explanation:
add 7a and 3a, and add 5b to 2b,
you're left with 10a + 7b, times two to both, and you have
20a + 14b
so the answer is gcd(20a,14b)
i have no clue i haven't done this before so thats what i'm guessing happens? good luck :,)
750/x=25/100
750x100=75,000
75,000/25= 3,000
75,000+3,000= 78,000
Answer:
The solution set to the absolute value is:
or 
Negative real numbers are not included in the solution set, as for 
, 
.
Step-by-step explanation:
From Mathematics, we know that absolute values are defined by the following characteristics:
1) For 
, 
2) For ,
Then, if , then the solution set to the absolute value is:
or
Negative real numbers are not included in the solution set, as for , .
Answer:
Option C. $30
Step-by-step explanation:
As per question buyers are willing to pay $135 per tuning. If David demands more than this amount producer will not choose David to tune.
As we can see on first week David is willing to tune the first piano for $115,
So surplus for producer will be
135 - 115 = $20
Surplus for second week for producer will be
135 - 125 = $10
Since David is willing to tune the third and fourth piano for $140 and $175 then the producer will not choose David for tuning.
Therefore, total surplus for the producer will be $20 + $10 = $30
Option C. $30 is the correct option.
