Roses bought=x
daisies bought=x-4
number of roses and daisies bought=x+x-4=2x-4

If Bob wants to use $53 he can go on 11 rides.
a) 4.71ft
b) 3.53ft^2
Step-by-step explanation:
Perimeter is 1/2 the circumference
1/2 Circumference = 2*pi*radius
Radius = 1/2 Diameter
Radius = 3/2 = 1.5ft
Circumference = 2*pi*1.5ft = 9.42
1/2 Circumference = 4.71
4.71ft is the perimeter.
The area is 1/2 that of a full circle
A = pi*r^2
A = 3.14*1.5*1.5
A = 7.065ft^2
1/2 A = 3.53ft^2
2n+5 = -13
subtract 5 from each side
2n +5-5 = -13 -5
2n = -18
divide each side by 2
n = -18/2
n = -9
X + 3 • ( 10 + y ) - 7x - 4
x + 30 + 3y - 7x - y
x - 7x + 3y - y + 30
-6x + 2y + 30
