If the perimeter is 98 cm, the sum of the lengths of two adjacent sides is 49 cm.

... (2x -1) + (3x +5) = 49 . . . . use the given information and relation

... 5x +4 = 49 . .  . . . . . . . . . simplify

... 5x = 45 . . . . . . . . . . . . . . . subtract 4

... x = 9 . . . . . . . . . . . . . . . . . divide by 5

The left side dimension is then

... 2x -1 = 2·9 -1 = 17 . . . . cm

The top dimension is

... 3x +5 = 3·9 +5 = 32 . . . . cm

The rectangle is 17 cm by 32 cm.

What is two and two fourths plus one third
kkurt [141]

Answer:

2 5/6

Step-by-step explanation:

2 2/4 + 1/3

First, you have to make the bottoms of the fraction the same, by figuring out the lowest common denominator. In this case it would be 12. 4x3 = 12. 3x4 = 12.

Multiply the top number by the same number you multiplied the bottom by.

We multiplied the 4 by 3, so we would also multiply the 2 by 3 (which would be 6).

Do the same for the second fraction. 1x4 = 4.

Now we have 2 6/12 + 4/12. We add the top numbers together and we get 10/12.

Now we have to reduce the fractions. We can do this in this situation by just dividing the top and bottom numbers by 2.

2 5/6
