3 1/2 pound = 7/2 pounds.
We know that the dog eats 7/2 (3.5) pounds every 21 days since there are 7 days in a week and Mr.Z only buys dog food every 3 weeks.
Set up a proportion. <u>3.5 lb</u> = <u> x </u><u>
</u> 21 days 365 days
<u>
</u>Cross multiply and divide. 3.5 lb x 365 days = 1277.5 / 21 days = 60.83 lb
<u>
</u>
Answer:
Around 25 pages / 1.5 minute(s)
Step-by-step explanation:
18 / 12 = 1.5 minutes per paper.
So, 18 + 18 = 36 + 1 = 37 minutes
12 + 12 = 24 + 1 = 25
37 / 25 = 1.5
(3x +4) + (6x + 5) = 90*
*note that complementary = 90, supplementary = 180
9x + 9 = 90
9x = 90 - 9
9x/9 = 81/9
x = 9
