Answer:
These are confusing Beth , b/c you have to remember that they will add to 100%
Step-by-step explanation:
so
green = 3* yellow
100% = green + yellow + 35% + 25%
100% = 3* yellow + yellow +60%
40% = 4* yellow
10% = yellow
30% = green
there are 14 purples in the bag , which is 35% of total
14/.35 = 40
there are a total of 40 pins
so
4 are yellow (10% of 40 or 40* 0.1)
12 are green (30% of 40 or 40*0.3)
14 are purple (35% of 40 or 40*0.35)
10 are grey (25% of 40 or 40*0.25 )

Answer:
17 boys and 11 girls
Step-by-step explanation:
Create a system of equations where b is the number of boys and g is the number of girls:
b + g = 28
b = g + 6
Solve by substitution, by substituting the second equation into the first one:
b + g = 28
(g + 6) + g = 28
2g + 6 = 28
2g = 22
g = 11
So, there are 11 girls.
Since there are 6 more boys than girls, there are 17 boys.
So, there are 17 boys and 11 girls in the class.
Answer:
x=4
Step-by-step explanation:
-7x=-28
-7 -7
x=4
Divide both sides by -7. A negative divided by a negative will give you a positive. So the answer would be x=4.
