Answer:
The greatest number of groups he could have made is 4 groups
Each of the four groups will have:
4 Squares each
7 circles each
Step-by-step explanation:
16 squares
28 circles
Find the highest common factor of 16 and 28
16: 1, 2, 4, 8, 16
28: 1, 2, 3, 4, 7, 14, 28
The highest common factor of 16 and 28 is 4
This means the greatest number of groups he could have made is 4 groups
Each of the four groups will have:
16 squares = 16 / 4
= 4 Squares each
28 circles = 28 / 4
= 7 circles each
Each of the four groups will have:
4 Squares each
7 circles each
Substitute y = 2x + 3 into y = -x - 9
2x + 3 = -x - 9
Solve for x in 2x + 3 = - - 9
x = -4
Substitute x = -4 into y = 2x + 3
y = -5
Therefore,
<u>x = -4</u>
<u>y = -5</u>
