Answer:
It will cost approximately $16.12 to varnish all the wooden planks.
Step-by-step explanation:
We are given the following in the question:
Number of rectangular planks = 12
Dimension of the rectangular wooden plank:
Length = 8 feet
Width = 3 feet
Area covered by I bottle of varnish = 125 Square feet
Cost of 1 bottle of varnish = 3.50 units
Area of 1 rectangular plot =

Total area to be covered by varnish =

Number of varnish bottles required =

Cost of varnishing =

Thus, it will cost approximately $16.12 to varnish all the wooden planks.
Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or ...
Answer:
1.53x−14.23
Step-by-step explanation:
<em>simplify: </em>
5.03x−8.03−(3.5x+6.2)
<em>Distribute the Negative Sign:</em>
=5.03x−8.03−1(3.5x+6.2)
=5.03x−8.03−1(3.5x)+(−1)(6.2)
=5.03x−8.03−3.5x−6.2
<em>Combine Like Terms:</em>
=5.03x−8.03+−3.5x−6.2
=(5.03x−3.5x)+(−8.03−6.2)
=1.53x−14.23
