Step-by-step explanation:
2y - 3 = 4y + 6
-2y - 3 = 6
-2y = 9
y = -9/2 = -4.5
If we let p and t be the masses of the paper and textbook, respectively, the equations that would best represent the given in this item are:
(1) 20p + 9t = 44.4
(2) (20 + 5)p + (9 + 1)t = 51
The values of p and t from the equation are 0.6 and 3.6, respectively. Thus, each paperback weighs 0.6 pounds and each textbook weighs 3.6 pounds.

Given: angle = 25°, hypotenuse = 100, opposite = ???


For this case we must factor the following expression:

We rewrite the middle term as a sum of two terms whose product is

And whose sum is

These numbers are:
-5 and -3
So:

We factor the maximum common denominator of each group:
We take common factor
