Answer:
x=8
y=16
Step-by-step explanation:
2x+2y=48
3x+y=40
Ther is many ways to solve this, one of them is clearance:
WE CLEAR AN UNLOCKED (X) AND REPLACE IT IN THE OTHER
x= (40-y)/3
2[(40-y)/3] +2y=48
(80-2y)/3 +2y=48
(80-2y+6y)/3=48
80+4y=48(3)
4y=144
y= 144/4
y=16
x=(40-y)/3
x=(40-16)/3
x=24/3
x=8
Answer:

Answer:
The answer is 8 rows.
Step-by-step explanation:
It is given that each row contain only 5 circles and there are 40 circles in the array. In order to find the numbers of row, you have to divide the total of circle by the number of circle in each row :
total = 40 circle
each row = 5 circle
5 circles = 1 row
40 circles = x row
x = 40/5
= 8 rows
