Step-by-step explanation:
use the formula 1/2(base1+base)x height
To write an equation to represent a given information, the equations are to
expresses the information conveyed in the situation.
The two equations that represent the given information are;
- <u>5.6·x + 4·y = 133.6</u>
Reasons:
The given information are;
Mass of the large boxes = 5.6 kg
Mass of the small boxes = 4 kg
Number of boxes delivered = 25 boxes
Total mass of the boxes delivered = 133.6 kg
Number of the 5.6 kg box delivered = x
Number of the 4 kg boxes delivered = y
Required:
To form two equations in terms of <em>x</em> and <em>y</em> to represent the situation.
Solution:
The two equations are;
- The number of boxes delivered = <u>x + y </u><u>= 25</u>
- Total weight of the boxes delivered = <u>5.6·x + 4·y </u><u>= 133.6</u>
<em>Solving the above equations with a graphing calculator gives;</em>
