Answer: Michael is 72 while Ann is 36.
Step-by-step explanation: Let X represent Michael's age and Y represent Ann's. From the first sentence, 
Y=2X. (eqn 1)
14+X=Y-22 (eqn 2)
X-Y=-22-14 
X-Y=-36; But Y=2X. 
Therefore, X-2X=-36; -X=-36; X=36. Hence, Y=2*36; Y=72. 
 
        
             
        
        
        
Answer:
26
Step-by-step explanation:
(21+31+36+28+26+x)/6=28
21+31+36+28+26+x= 28×6
142+x =168
x=168-142
x=26
 
        
             
        
        
        
Hi there! 
To find the volume of a rectangular prism, we need to multiply the dimensions together. 
12×8×4 = 384
So, the answer is 

Hope this helps!
 
        
        
        
Okay. So we have to do division, because you're dividing 4 1/4 (17/4) tablespoons of medicine by 5 doses. The formula for multiplying fractions is keep, change, flip. 17/4 * 1/5 is 17/20. 17/20 tablespoon of medicine is supposed to be taken in each dose.
        
             
        
        
        
The answer is x=6 and y=4.
6+4=10
and 8 times 6 + 12 times 4 is 96.
