Answer:
AB = 21
Step-by-step explanation:
So we have two triangles (AEB and ADC), and they're similar by AA
Now, you can find the ratio of similitude by checking AE/AD which is 14/26 = 7/13
AB/AC = 7/13
Take AB as x aight
x/x+18 = 7/13
x=21
Answer:
$5.25 Dollars
Step-by-step explanation:
I know that if you divide 21 by 3 you get 7. So, 2/3 of 21 is 14. He spent 14 dollars at the music store. This means that he has 7 dollars left. From here he spend 1/4 of 7 dollars on a drink. 1/4 of 7 is $1.75. This means that he has 5.25 dollars left after he bought the drink! :)
