7k/3 = 21
x 3 x3
7k = 63
/7 /7
k = 9
(7(9)/3 = 21 = 63/3 = 21 = 21 = 21)
Answer:
I think it is 3 feet
Step-by-step explanation:
12:9 is equal to 4:3
4:? should also be equal to 4:3, so ?=3
Hope this helps
let me know if it does and if it is right

7 muffins
Step-by-step explanation:
9x9=81
88-81=7 muffins
So for QC to be a perpendicular bisector, it needs to make BC=CD lets label BC as X. BC+CD=BD. Because BC=CD, X+X=BD or 2X=24. Thus X=12. Thus BC=12. Now PB is a perpendicular bisector of AC so PB makes a right angle with AC at point B. PC=13(given) so because we have a right triangle, we can use the hypotenuse theorem so PC^2=BC^2+PB^2 or 13^2=12^2+PB^2 so 25=PB^2 so PB=5
Hope this helps!
