I think there was 17 boys at the beginning of the concert. But i don't know how to put it in terms of P
Answer:
Step-by-step explanation:
2(x + 2)/3 = 6
multiply by : 3
2(x + 2) = 18
2x+4 = 18
2x = 18-4=14
x=14/2
x=7
Perimeter of a square=4*side length
2=4*side length
2/4=side length
.5 or 1/2=side length
Hope this helps!
(b)+(b+45)=215
b = # of boys
there are 45 more girls than boys and 215 students total.
minus 45 on both sides leaving you with
(b)+(b)=170
combine like terms leaving you with
2b=170
divide both sides by 2
b=85
there were 85 boys
85+45=130
(the 45 for the # of girls more than boys)
there were 130 girls.
Answer:
slope = -2/3; y-intercept is point (0, -6)
Step-by-step explanation:
y = -6 - 2/3 x
y = -2/3 x - 6
y = mx + b
m = slope = -2/3
b = y-intercept = -6
Answer: slope = -2/3; y-intercept is point (0, -6)
