Quincy is using 320 pieces of stone tile to make red white and blue mosaic. If 20% of the pieces are blue and 35% are white how
many pieces are red?
1 answer:
100% = 320
20% = Blue tiles
35% = White Tiles
100% - 55% = Red Tiles = 45%
45% of 320
320 x 0.45 = 144 Red tiles

Answer:
f^-1(x)=1/2x+5
Step-by-step explanation:
y=2x-10
inteechange 'y' with 'x'
x=2y-10
make 'y' the subject
2y=x+10
divide by 2both sides
y=(x+10)÷2
y=1/2x+5
f^-1(x)=1/2x+5
