Answer:
9.5 inches
Step-by-step explanation:
The relationship is presumed to be ...
(first week's growth) + (second week's growth) = (growth in two weeks)
(first week's growth) + 3.43 inches = 12.93 inches . . . . . fill in the numbers
Subtract 3.43 from both sides of the equation:
first week's growth = 12.93 inches - 3.43 inches
first week's growth = 9.50 inches
The plant grew 9.50 inches in the first week.

Answer:1800 words
Step-by-step explanation:
Multiply how many words per minute she types by how many minutes she types. In this case 60x30=?. The easy way to do this is drop the 2 zeros and do 6x3=18. In the original equation we dropped the 2 zeros. Now we add them back on the back of the 18 and get 1800.
Here we have to know the conversion between feet and inches.
1 Feet = 12 inches (This is given and is to be known)
So the 5 feet wide footbridge when converted to inches would be about 5*12 = 60 inches
The width of the footbridge in inches = 60 inches
Each wooden plank is 6 inches,
So the number of wooden planks that are required to build the foot bridge of 60 inches = 60/6 = 10 planks
Hence, the path path is 10 planks wide
