Answer:
Number of red squares used are 79.
Step-by-step explanation:
Given that Adam had used 84 white squares.
White squares used are 20 more than that of yellow.
Let yellow squares used = [tex]x[/tex]
([tex]x[/tex] + 20) is the number of white squares used.
Also given that 15 more red than yellow
So, Number of red squares used = [tex]x+15[/tex]
To find:
Number of red squares that Adam used.
Solution:
As per given statement:
White squares used =
[tex]x+20=84\\\Rightarrow x=64[/tex]
[tex]\therefore[/tex] Number of yellow squares used, [tex]x[/tex] = 64
Number of red squares = [tex]x + 15 = 64+15 =79[/tex]
So, Number of red squares used are 79.
