Answer:
None of the above
Step-by-step explanation:
20 x 4 = 80
20 + 20 +20 =20 = 80
12 muffins = 1 cup
x = 1 1/4 cups
x = 5/4 cups
cross multiply:
12*5 / 4 = x * 1
3 * 5 = x
x = 15
Answer = 15 Muffins
Other way:
1 1/4 cups = how many muffins
you already know 1 cup = 12 muffins
remaining 1/4 cups = how many muffins?
1/4 of 12 = 3
So 12 + 3 = 15 muffins
The answer is csc(x)cot(x)tan(x) over sec(x)
Answer:
$243.
Step-by-step explanation:
We can use algebra here.
Let x = the original price.
Then 1/3 x - 27 = 54
1/3x = 54 + 27 = 81
x = 81 / 1/3
x = 81 * 3
x = $243 (answer).
