The driveway in front of the brown house is 35 feet long and the driveway in front of the red house is 7 yards, 9 feet long. Whi
harkovskaia [24]

Answer:

The first house has the longest driveway by 5 feet

Step-by-step explanation:

1) You must change the 7 yards and 9 ft to just feet. We can do this by measuring the conversion. 1 yard = 3 feet.

2) Now that we know this conversion, we can change the 7 yard and 9 feet to feet. In order to do this we multiple the 7 yards by 3 to get how much feet are in the 7 yards. When we do this, we get 7 yards = 21 feet. Now we add 9 to 21 to get the total legth of the second driveway which is 30feet.

3) The first house had a 35 ft driveway while the second house had a 30 feet driveway. The first house has a longer driveway by 5 feet.

Please help me. I didn't get it
Georgia [21]
\frac{3}{10} + \frac{2}{5}
 
Multiply the \frac{2}{5} by 2 on both sides to get a common denominator of 10. You should end up with \frac{4}{10}.

\frac{3}{10} + \frac{4}{10} = \frac{7}{10}

Get a common denominator between \frac{7}{10} and \frac{5}{15} to compare them -- a common denominator is 30. Multiply the \frac{7}{10} by 3, and \frac{5}{15} by 2.

\frac{21}{30} and \frac{10}{30} 
The \frac{7}{10} is obviously much larger than \frac{5}{15}.

Now look at the answers. Which are true?

B and E are easily seen as true, because we know that the total of \frac{5}{15} is not reasonable/right.

The 2 statements that are true are (B) and (E).
