A worker is installing blue and white square tiles in a kitchen. Blue tiles have different lengths than white tiles. A row of 8
blue tiles and 16 white tiles has a length of 39 inches. A row of 40 blue tiles and 8 white tiles has a length of 42 inches. Write a system of equations that represents in inches the relationship between the length of a blue tile and the length of a white tile.
8x+16y = 39 and 40x+8y = 42 are the system of equations that represents in inches the relationship between the length of a blue tile and the length of a white tile.
Every triangle’s inner angles’ addition equals to 180° So if we find the x: 38°+x+2°+x=180° 40°+2x=180° 2x=180°-40°=140° x=140°/2 x=70° Now if we find the I hope this helped :)
You divide $1.20 by 18 to get the amount per piece which is about $0.067. Then you multiply 0.067 by 27 for the amount for 27 pieces which is about $1.81 rounded to $1.80.
