3x + 5y = 1 . . . . . . . . (1)
7x + 4y = -13 . . . . . . .(2)
(1) x 7: 21x + 35y = 7 . . (3)

Answer:−1(2n + 1)
Step-by-step explanation:
14/25 of the souvenirs purchased at the zoo gift shop were stuffed animals
of the stuffed animals purchased: 10/21 were bears
If you want to know what fraction of the souvenirs purchased were stuffed bears, you can calculate this using the following steps:
10/21 * 14/25 = (10 * 14) / (21 * 25) = 140 / 525 = 4 / 15
Result: 4/15 of the souvenirs purchased were stuffed bears.
Answer:
Area = 30 square units
Step-by-step explanation:
First, let's try to visualize the problem:
(-2, 4) • | • (3, 4)
|
|
___________|___________
|
(-2, -2) • | • (3, -2)
|
|
Let's find the side lengths;
(-2) - 3 = |-5|, the Base of the rectangle is 5 units.
4 - (-2) = 6, the Height of the rectangle is 6 units.
The formula for area of a rectangle is B × H.
5 × 6 = 30, so the area of the rectangle is 30 units.
