32.49y+56.25y
Take 5.7*5.7=32.49
Take 7.5*7.5=56.25
Those are the areas of each square shaped areas in Roberts backyard. Multiply each by then cost of y and then add both together...
78 (1 + 2 + 3 . . + 12) so 78/3 = 26 and 11 + 12 + 1 + 2
10 + 9 + 3 + 4
8 + 7 + 6 + 5
that means you will draw one line below the 11 and across to below the 2 and the second line would be above the 8 and across to below the 4.
Seeing is believing . . .draw and label a clock face then add the two lines!
Answer:
30 students
Step-by-step explanation:
The problem above can be solved using a Venn diagram :
Using the information given :
The number of students competing :
Band and chorus only (BnC) only = 5 - 4 = 1
Band and Orchestra (BnO) only = 6 - 4 = 2
Chorus and Orchestra (CnO) only = 7-4 = 3
Chorus only (C) = 13 - (1+4+3) = 5
Band only (B) = 14 - (1+4+2) = 7
Orchestra only (O) = 17 - (2+4+3) = 8
The Total Number of Bayview students who competed :
(8+7+5+3+2+1+4) = 30
60 / 96 = 25 / q
5 / 8 = 25 / q
5*q = 8 * 25
5q = 200
q = 40
Check:
60 / 96 = 25 / 40
5/8 = 5/8 :)
Simply present that you would split them up as a factor of two. ( make two lines going either vertically or horizontally. place in varriations, a marble in one line and a marble in the other and then count the leftover
