Answer:
16
Step-by-step explanation:
80% of 20 is 16
Answer:
x=(y+9)/(1+2w)
Step-by-step explanation:
x-9+2wx=y
We make x the subject
x+2wx=y+9
x(1+2w)=y+9
Divide both sides by (1+2w)
x(1+2w)/(1+2w)=y+9(1+2w)
x=(y+9)/(1+2w)
Answer:
x = 12, sides = 23
Step-by-step explanation:
Since is equilateral, all three sides are equal. Therefore:
Substituting y = x + 11:
Solving for x:
Substituting x = 12:
Thus, <em>x</em> = 12 and the length of each side is 23.
