Solution
- The line segment CD is written as follows:
Solution:
<u>Note that:</u>
<u>Using cross multiplication:</u>
- (3x)/20 = (4x + 2)/28
- => (3x) × 28 = (4x + 2) × 20
<u>Simplifying both sides:</u>
<u>Subtracting 80x both sides:</u>
- 84x = 80x + 40
- => 84x - 80x = 80x + 40 - 80x
<u>Simplify the LHS:</u>
- => 84x - 80x = 40
- => 4x = 40
- => x = 10
24-24=0
And we have 24-28. so after 24-24=0 we still have to subtract 4 more.
0-4=-4
The answer is therefore -4
The six pack of soda that costs 2.70 is a better deal than the soda that costs .50 because technically if you bought the 6 pack the soda would be 45 cents
