The answer is C, 55x-26
-11x*-5 that is 55x
7*-5=-35
9-35=-26
so the ending expression is 55x-26
7+7+7+7+7+7+7+7+7=63 9+9+9+9+9+9+9=63 9×6=54 54+9=63
3.5 hours is 3 hours and 30 minutes.

Answer:
<h3>3 : 2 : 4</h3>
<h2>CALCULATIONS</h2>
<h3>Let;</h3>
<h3>Kofi's age = 9</h3>
<h3>kwaku's age = 2/3 *9 = 6 </h3>
<h3>Yaw's age = 2(6) = 12</h3>
<h3>ratio of ages = 9 : 6 : 12</h3>
<h3>Simplest form = 3 : 2 : 4</h3>
We have a proportion: 60/?= 20/100
Cross multiply:
20*?= 60*100
⇒ ?= 60*100/20= 300
60 minutes is 20% of 300 minutes~
