Omar spent 600 dollars for earning 1800 reward points.
<em><u>Explanation</u></em>
Omar earns 300 reward points for every 100 dollars he spends.
Suppose, he spent 
dollar for 1800 reward points.
Now <u>according to the ratio of "amount of money spent" and "reward points"</u> , the equation will be......
Thus, Omar spent 600 dollars for earning 1800 reward points.
Step-by-step explanation:
a. y = ¾x +6
b. y = 6/4 x -2

d. y = -1/7 x -4
Answer:
735,130.
Step-by-step explanation:
The order of election of the 3 representatives does not matter so it is a combination.
The number of possible combinations
= 165! / 162! 3!
= (165 * 164 * 163) / (3*2*1)
= 735,130.
Answer:
1. a + b + c = 180
2. b + d = 180
3. d = a + c
Step-by-step explanation:
1. a + b + c = 180:
Angles in a triangle add up to 180
2. b + d = 180:
Angles in a straight line equal 180 because they are supplementary angles
3. d = a + c:
ΔACD is an exterior angle, and ΔACB is interior adjacent, hence ∠a and ∠c add up to ∠d
