5x(8 - 4)/4 - 2
Remember to follow PEMDAS.
First, subtract 8 and 4
8 - 4 = 4
5x(4)/4 - 2
Next, follow the left -> right rule, and multiply 5x and 4
5x(4) = 20x
Divide by 4
20x/4 = 5x
Finally, note that one has a variable, and the other has a constant, and so you cannot combine.
5x - 2 is your answer
hope this helps
Answer: Todd used 27 black tiles.
Step-by-step explanation:
Let x represent the number of black tiles that Todd used.
Todd uses 21 white tiles & some black tiles to make a mosaic. This means that the total number of white and black tiles that Todd used is 21 + x
Each tile has an area of 3 square centimeters. This means that the total area covered by the white tiles is
21 × 3 = 63 square centimeters
Also, the total area covered by the black tiles is
3 × x = 3x square centimeters
The mosaic has a total area of 144 square centimeters. This means that
3x + 63 = 144
3x = 144 - 63
3x = 81
x = 81/3 = 27
