For every 5 green picks, 2 are orange. Adding 5+2 makes 7. 21/7 = 3
There are 3 sets of 5 green 2 orange picks. So 2*3 = 6.
There should be 6 orange picks.
You can also just count. 5 + 2 = 7. Adding another 5 picks = 7 + 5 + 2 = 14. Another 5 picks, 14 + 5 + 2 = 21. Adding up the orange picks, which is the twos, we get 6.
Length = 7 Width = 2
Step-by-step explanation:
L = Length
W = Width
L=9w-11
2L+2W=18
2(9W-11) + 2W = 18
18W - 22 +2W = 18
20W -22 = 18
20W = 40
W = 2
L = 9(2)-11
L=18-11
L=7
-15-(-18)=-15 +(-18)=-33
-×-=+ +×-= -
-15×-(-18)= 3
-15×+(-18)=-33
3-33=-33
-30=-30
For example, the three 2s.
in the box show that there are 3 groups of 2 objects each.You can write the multiplication equation 3 2 = 6 to show that 3 groups of 2 equals 6 in all.You can also write the division equation 6 2 = 3 to show that 6 divided into groups of 2 equals 3 groups.
