Answer:
348
Step-by-step explanation:
Multiply 20 x 17 first. Then add that value to 20 and -17. The result is the answer.
I get 348
First, you would divide 9/72 by 72/72 and would get .125. So every book weighs .125 kg.
Then, to find how much 80 book weigh, you multiply 80 times .125 and get 10.
Lastly, to find how many books weigh 6 kg you, keep multiplying .125 by a number until you reach 6 kg. In this case the number is 48. So 48 books weigh 6 kg.
Hope this helped! ;D
If we know the three corresponding sides form the same ratio, then we can use the SSS similarity theorem
If we know that 2 pairs of angles are congruent, then we can use the AA similarity theorem
Finally, if we know that two sides are proportional with the congruent angles between the two sides, then we can use the SAS similarity theorem

Answer:
C
Step-by-step explanation:
because the limo charges 30 and 4 per person and the person is x . The other limo automatically charges 70 plus 2 per person which is x hence 30+4x=70+2x
Answer:
Step-by-step explanation:
those angles are congruent because they are vertical angles
6x+4 = 58 ; subtract 4 from both sides
6x = 58-4 ; combine like terms
6x = 54; divide both sides by 6
x= 9
