Answer: 7 inches
Step-by-step explanation:
If x is the first piece, and the second piece is twice as long, then the second piece is 2x.
If the third piece is three times as long as the first piece, x, then the third piece is 3x.
The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.
42 = x + 2x + 3x
42 = 6x
42 = 6x
7 = x
The first piece is 7 inches long.

Answer and Step-by-step explanation:
Although the question is not complete, but with the context of the question, they are most likely going to ask for the total distance travelled or the total time or speed. So let's work on that.
Total time travelled = (3 + 5 + 4) = 12mins
Total speed travelled = (0.50 + 0.00 + 0.40)miles/min = 0.90mile/min
The 0.00 represents the period he was at rest admiring an antique car. At this moment, he was not moving so his speed is 0.
Total distance travelled = total speed x total time = 0.90miles/min x 12min = 10.8miles
Answer:
12900
Step-by-step explanation:
umm first you write down the number of zeros (but only the zeros at last if a zero comes in middle or between other numbers, then you must have to multiply it) and then multiply the remaining numbers. I am not good at explaining. ;)
Answer:
F=0 or (7/3)
Step-by-step explanation:
When F is 0, the equation reads -0(3(0)-7)=0. The outside 0 will multiply by everything and make it equal 0. When F is 7/3, the inside of the parenthesis read 3(7/3)-7. This equals 7-7. It'll end up being (7/3)0, which equals 0.
