The cheap one is 8 while the costly one is 17.5

Step-by-step explanation:

Let the cheaper candle be x

And the costly candle b y

X+y = 25.5 equation one

2.20x +7.3y = 25.5(5.7)

2.2x + 7.3y = 145.35equation two

Solving simultaneously

X+y = 25.5

2.2x + 7.3y = 145.35

2.2X+2.2y = 56.1

2.2x + 7.3y = 145.35

5.1y= 89.25

Y= 17.5

X+y = 25.5

X+ 17.5 = 25.5

X= 25.5-17.5

X= 8

The cheap one is 8 while the costly one is 17.5

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
