x+5=5
Step-by-step explanation:
This is an equation where you are actually solving it. The others are expressions.
Answer:
- Hayes family: 35 hours
- Rodrigues family: 40 hours
Step-by-step explanation:
Let x and y represent the usage hours by the Hayes and Rodrigues families, respectively. The problem statement gives us relations that can be used to write equations for volume of use and for total hours.
15x +30y = 1725 . . . . . total liters of use
x + y = 75 . . . . . . . . . total hours of use
The second equation lets us write an expression for y:
y = 75 -x
This can be substituted into the first equation to give ...
15x +30(75 -x) = 1725
-15x + 2250 = 1725 . . . . . . simplify
-15x = -525 . . . . . . . . . . . subtract 2250
x = 35 . . . . . . . . . . . . . . divide by -15
y = 75 -35 = 40
The Hayes family used their sprinklers for 35 hours; the Rodrigues family used theirs for 40 hours.
The option that shows what all the polygons have in common is that;
B. Each appears to have exactly one pair of parallel sides.
<h3>Polygon</h3>
Looking at the polygons given, we can see that;
- Polygon A has 4 sides and one pair of parallel sides and it is a quadrilateral because it has 4 sides.
- Polygon B has 4 sides and one pair of parallel sides and it is a quadrilateral because it has 4 sides.
- Polygon C has 6 sides and so is not a quadrilateral but a hexagon and it has a pair of parallel sides.
- Polygon D has 5 sides and so is a pentagon but has a pair of parallel sides.
Looking at all the polygons the only common statement is that they a pair of parallel sides.

122.57 ×4=490.28
Total was 555.28 which would be a difference of 65.00
136.71 ×4=546.84
Total was 585.34 which would be a difference of 38.50
Subtract the two differences which is $26.50
