Landen spent L hours at the beach last weekend. Matéo spent 15% fewer hours at the beach than Landen did
fenix001 [56]

Answer: B, D, and E

0.85L

or

L-0.15L

or

L(1-0.15)

or

L - \frac{15}{100}L

L - \frac{3}{20}L

Step-by-step explanation:

L is the number of hours Landen spent at the beach. Mateo spent 15% less time. This means he spent 85% of it. So 0.85 times L. We can also calculate it by subtracting the difference between the two kids. - 15%. 15% is 0.15L or \frac{15}{100}L. We subtract by L-0.15L or as L - \frac{15}{100}L. This fraction can simplify to L - \frac{3}{20}L

The length of a rectangle is seven more than double the width. If the perimeter is 22 inches find the dimensions
lubasha [3.4K]

Answer:

width = 1 1/3 inches

length = 9 2/3 inches

Step-by-step explanation:

let 'w' = width

let '7+2w' = length

P = 2l + 2w

22 = 2w + 2(7+2w)

22 = 2w + 14 + 4w

8 = 6w

w = 4/3 or 1 1/3

substitute 1 1/3, or 4/3, to find length:

l = 7 + 2(4/3)

l = 7 + 8/3 or 9 2/3

The graph below shows the time Andrea spent reading one day. Write a few sentences to describe the relationship between the time
Alex777 [14]

Answer:

Step-by-step explanation:

Well, there are several  relationships you can describe.  As time increases how does number of pages  react?  Like does it increase or decrease.  Is it always increasing or decreasing by the same amount?  If it's not all the same how do different parts look different.  

There aren't any actual numbers, so you can't say specifically how they relate, like you can't say she read 5 pages a minute or something.
