Assuming we're solving for x, all that needs to be done is to add 5 on both sides.
x - 5 >= -2
+5 +5
x >= 3
Let the selling price be S. The selling price based on selling price is found from:
Cross-multiplying, we get:
0.75S = S - 150
which when solved for S gives a selling price = $600.
To find the selling price based on cost, the following equation applies:
Cross-multiplying, we get:
112.50 = S -150
which when solved for S gives a selling price = $262.50.
Answer:
1: L = 5
W = 7
2: A = lw
3: 35
4: 18
5: You have to add them up because it is 1 shape broken up into different parts.
6: 53

if x =7 then plug in 7 for x
4(7) - 2((7)+a) = 8
28 - 14 -2a = 8
14 - 2a = 8
-2a = -6
a = 3
