Answer:
The answer is attached below
Step-by-step explanation:
Let the numbers be x and y.
X-11=y
X+y+7=90 or x+7=-y+90
Add the 2 equations together.
2x-4=90
2x=94
X=47
So 47+y+7=90 so y+54=90 so y=36
Check in other equation:
X-11=y
47-11=36
36=36 it works
So your numbers are 47, 36
bearing in mind that a diagonal line from the center of a square will give us an isosceles triangle, Check the picture below.
Answer:
4 1/12 sq. ft
Step-by-step explanation:
To know the amount of area that Pete’s bed have more than Fluffy’s bed, we simply calculate the area of both beds then subtract the smaller from the larger.
The area of Fluff’s bed would be 3 * 21/12 = 63/12 Sq ft
The area of Pete’s bed would be 4 * 28/12 = 112/12 sq ft
The difference in area is thus: 112/12 - 63/12 = 49/12 = 4 1/12 sq. ft
