Answer: 620≥ 427.57+ 11.38(4)+ (31.41) +57.75x
Step-by-step explanation:
So our limit is the 620$ that he has to spend. We know for a fact that the bike costs about 427.57 dollars. 4 $11.38 reflectors are purchased as well as gloves for 31.41. Now however many outfits he can purchase cannot exceed or go over his money limit of 620 so the variable (x) represents how many outfits he can buy without going over.
Answer:

Step-by-step explanation:

First, simplify

The area of a circle is A=πr².
Since π is about 3.14 we can substitute that into the equation.
So A=3.14×r²
We can substitute the given radius for r.
A= 3.14 × 5²
When a number is squared, or has the two over it, we multiply it by itself.
5 × 5= 25
A= 3.14 × 25
Simplify this and the area of the circle is about 78.5
A≈78.5
3x + 2y = 6....solution (0,3)
-5x + y = -10...solution (1,-5)
x - 4y = 8...solution (4,-1)
-6x - 5y = 30...solution (0,-6)
Answer: $25
Step-by-step explanation:
20% = 0.20
125 x 0.20 = 25
$125 + $25 = $150 (the entire bill)
