Answer:
Let the total no of girls be x
the number of boys=7:5
total no of students =20
now,
no of girls =7/5=x/20
or, 20*7=5x
or 140=5x
or,x=140/5=28
therefore the number of girls =28
(3x+3) + (4x + 2)
------------------------- = 13
2
13(2) = (3x+3) + (4x+2)
26 = 3x + 3 + 4x + 2
26 = 7x + 5
26-5 = 7x
21 = 7x
x = 21 ÷ 7
x = 3
Answer:
Step-by-step explanation:
In the first pattern, there were 6 sticks
In the second pattern, there were 10 sticks.
In the third pattern, there were 14 sticks.
Based on the pattern, we see that each time, 4 more sticks are added and that the initial amount of stick is 6.
Thus: the equation for how many sticks there would be in pattern n is:
# of sticks in pattern n = 6 + 4n
