Answer:
Q1:9
Step-by-step explanation:
Since the area of a triangle is basexheight divided by 2, than (12 x __)/2 = 54
15n-22
(: hope it's correct!
You need to show the data above
Since Carmen gives two coins to Frankie for every five that she gets, she effectively only gains 3 coins at a time. Therefore, if she has 9 coins, Frankie must have 6.
The equation 11x + 10y = 32 is a linear equation, and the solution to the linear equation 11x + 10y = 32 is 
<h3>How to solve the equation?</h3>
The equation is given as:
11x + 10y = 32
Subtract 11x from both sides
10y = 32 - 11x
Divide both sides by 10

Hence, the solution to the linear equation 11x + 10y = 32 is
