Answer:
11
Step-by-step explanation:
<em>When you subtract a negative number, you add them.</em>
<em>Example: 5 - (-5) = 5 + 5 = 10</em>
<em>Example: 1 - (-14) = 1 + 14 = 15</em>
<u>Step 1: Subtract</u>
8 - (-3)
8 + 3

Answer: 11
Let
x = number of common cars
y = number of suvs
we can write the following system of equations
x-y = 12
x = 1.429y
Solving the system we have
x-y = 12
1.429y-y = 12
and (1,429-1) = 12
y = (12) / (1,429-1) = 27.97202797
then,
x = 1429 * (27.97202797)
x = 39.97202797
answer
The number of suvs in the parking lot is 28
Supplementary angles, when added, equal 180 degrees
so < A + < B = 180...and if < A = 80
80 + < B = 180
< B = 180 - 80
< B = 100 <==
