Answer=24 blue marbles and 3 red marbles
r=red marbles
b=blue marbles
b=3(r+5)
27=b+r
substitue b for '3(r+5)'
27=3(r+5)+r
27=3r+15+r
27=4r+15
subtract 15 from both sides
12=4r
divide both sides by 4
3=r
There are 3 red marbles
27=b+r
27=b+3
subtract 3 from both sides
24=b
There are 24 blue marbles

(2,3) and (-1,-5)
Distance =√(-1-2)^2 +(-5-3)^2
Distance =√73 (diamter)
radius = (√73) / 2
area of semi-circle:
= 1/2 πr^2
= 1/2 π ((√73) / 2)^2
= 73 π / 8
= 9.125 π
area of triangle:
= 1/2 (8)(3)
= 12
Area of the figure = area of semi-circle + area of triangle<span>
</span>= 9.125π + 12
answer
9.125π + 12
