ANSWER

y = 5

EXPLANATION

The given isosceles tra-pezoid has legs

ab =  - 3y + 54

and

cd = 6y + 9

The base is bc=5y+2.

The length of the legs of the isosceles tra-pezoid are equal.

This implies that,

ab = cd

Thus,

- 3y + 54 = 6y + 9

Group similar terms,

54 - 9 = 6y + 3y

45 = 9y

Divide both sides by 9.

y =  \frac{45}{9}

y = 5

Kyra is using rectangular tiles of two types for a floor design. A tile of each type is shown below: Two rectangular tiles, rect
Rudiy27
Since there is no picture shown, I just plotted the given data points myself. That is shown in the attached picture. The blue rectangle is rectangle PQRS while the orange one is rectangle JKLM. I believe there are some choices for this question but you forgot to include. Nevertheless, I will give my observations from the given figure. 

The tile PQRS is bigger than tile JKLM. A rectangle is a two-dimensional shape that has two sets of equal parallel planes. Thus, its area is equal to the length multiplied by its width.

tile PQRS = (9-5)*(12-7) = 20 units²
tile JKLM = (6-4)*(10-5) = 10 units²

Tile PQRS is larger by 10 units².

Can someone help me I can't remember how to do ratios
omeli [17]

3 casseroles feeds 15 people

The ratio is 3:15

If you divide each of those by 3, youll find that 1 casserole feeds 5 people

1 : 5 is the ratio.

Divide 30 by 5 = 6

6 casseroles feeds 30 people.

6 : 30

35 divided by 5 = 7

7 casseroles feed 35 people

7 : 35
