Answer:
A because 12 x 2.25 is 54 and thats the price for 2 sozen
Answer:
Step-by-step explanation:
10 students participated in a Mathematics quiz. If the number of girls is 4 more than the number of boys, find the number of boys and girls who took part in the quiz
Solution: Number of girls = x
Number of boys = y
x + y = 10 -------------------(I)
Number of girls is 4 more than the number of boys
x - y = 4 ----------------------(I)
x = 4 + y
Substitute x = 4 +y in equation (I)
4+ y + y = 10
4 + 2y = 10
2y = 10-4
2y= 6
y = 6/2
y = 3
Plug in y = 3 in eqution (I)
x + 3 = 10
x = 10 - 3
x = 7
Number of girls = 7
Number of boys = 3
Diagonals of a rect. are equal...
diagonals bisect each each other...
from these two properties we get ,
4x-12 = 1/2 (7x-18)
2 (4x-12)=7x-18
8x-24=7x-18
x=6
