8 times 9 - 7 + 4 times 5
Use PEMDAS. Parentheses, Exponent, Multiply, Divide, Add, Subtract
Multiply:
8 times 9 = 72
4 times 5 = 20
72 - 7 + 20
Add:
72 + 20 = 92
Subtract:
92 - 7 = 85
8 times 9 - 7 + 4 times 5 is equal to 85.

Answer: C) 12</h3>
======================================================
Explanation:
There are 3 colors of sweaters {red, green, purple} and 2 colors of skirts {tan, black}
So far there are 3*2 = 6 different outfit combinations. Imagine a table with 3 rows representing the sweater colors and 2 columns representing the skirt colors. There would be 6 cells in the table representing each possible combination. One cell would have (red sweater, tan skirt) for instance.
For each of those 6 combinations, we also have 2 shoe colors. So overall we have 6*2 = 12 outfit combinations
The tree diagram is shown below. Note how there are 3*2*2 = 12 different paths to follow.
Since they have same y (2), it means this is a straight line. what you need to do is just find the distance between -4 and 7. distance between -4 and 7 is 7-(-4)= 11
x = 20 - -5 = 20 + 5 = 25
y = 16 - 1 = 15
<h2>
x = 25</h2><h2>
y = 15</h2>
