Answer:
52 people
Step-by-step explanation:
If you place 25 square tables in a line, the 23 tables in the middle can only seat 2 people each since the other two sides are touching two other tables. The end two tables can seat 3 people since only one of their sides is touching another table.
So multiply 23 by 2 to find out how many people are sitting in the middle and then add 6 people for the two tables on the end.
23(2) + 3(2) = 52 people
ensure all fractions have the same denominator
we require - = -
thus - - -
take out a common factor
= (- 7 - 4 - 5 )
= × - 16 = - 1
Answer:
78/20 or 39/10 or 3 9/10
Step-by-step explanation:
3 1/4 ÷ 5/6
3 1/4 = 13/4
KCF:
13/4 x 6/5 = 78/20 = 39/10 = 3 9/10
Answer:
4 + 5i
Step-by-step explanation:
To calculate this you have to combine the like terms until they cannot be combined any further:
7 + 10i + 4 - 10i - (7 - 5i)
11 + 0i - 7 - 5i
7 & 4 are liked terms so add them together + subtract 10i and 10i
4 + 5i <--- Final answer
Hope this helps!
