Lily paints 3 trees for a wall mural the middle tree is 2 1/2 ft tall the tree on the left is 3/4as tall as the middle tree the
raketka [301]

Answer:

Middle: 2.5  ft

Right: 4,375  ft

Left: 1,875 ft

Step-by-step explanation:

We know that a tree in the middle is 2.5 feet tall.

Now the tree on the left measures 3/4 of the tree in the middle, therefore:

2.5 * 3/4 = 1.875

Which means that the tree on the left is 1.875 feet tall.

Finally the tree on the right 1 3/4, which would be 1.75 times the tree in the middle, therefore:

2.5 * 1.75 = 4.375

Therefore the tree on the right is 4.375 feet tall.

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel. How old is Kevin now?
GuDViN [60]
Let k and d be the Kevin's age and the Daniel's age;
We have the equation:
k = 3 + d;
k - 2 = 4( d - 2 );
We have 3 + d -  2 = 4d - 8;
Then, d + 1 = 4d - 8;
9 = 3d;
d = 3.
Finally, k = 6 years.
