Answer:
1) 144 seconds
2) 12
3) 24
Step-by-step explanation:
1) First off how many times can 15 dived into 90? 6! So we know it <em>can</em> go into 90 and that it's by 6. Next is to add 24 (seconds) 6 times. This will lead you too 144. So 144 seconds is your awnser
2) All you have to do is dived 72÷6. Which gives you the amount of each pack .
3) You take the total of step number two and 288 earsers and dived. so 288÷12=24

Take the length as 'x'
Width = 2x - 2
Perimeter = 44 [ Formula = 2(l + w) ]
2 (l + w) = 44
2 (x + 2x - 2) = 44
2 (3x - 2) = 44
6x - 4 = 44
6x = 44 + 4
6x = 48
x = 48/6
<u>x </u><u>=</u><u> </u><u>8</u> => length
Width = 2x - 2 = 2(8) - 2 = <u>1</u><u>4</u><u> </u><u>units.</u>
Hope it helps!

Answer:
C= 27
G= 37
J=57
Z= 1
Step-by-step explanation:
These are the degrees because of the Triangle Sum Theorem which states that The sum of the measures of the angles in a triangle is 180°. So angle C for example is 27 because angle A is 53 and angle B is 100 add both of those and you get 153 so our equation would be 153+c=180, c being the angle, so then to solve this you do do 180-153 and that equals 27 so therefore, 153+27=180. This process applys to all the other angles as well ^w^
 
        
             
        
        
        
        
55% of 100 is 55
55+100=155
Selling price: $155
No problem! :)
