Let the number = 10x+y
x+y = 9
y-x = 1
(x+y)+(y-x) = 9+1
2y = 10
y = 10/2
<h3><u>y = 5</u></h3>
x+y = 9
9-y = x
x = 9 - 5
<h3><u>x = 4</u></h3>
<h2>So, your number is <u>45</u></h2>
... Hope this will help...

Answer:
28
Step-by-step explanation:
The ratio of the triangles is 12:15 which is equal to 4:5
Then you can use that ratio to find the ?
35 would be the 5 so 4 would be multiplyed by 7
Which is equal to 28
(2 - 2.82) ÷ 4 + 3.46
-0.82 ÷ 4 + 3.46
-.0.205 + 3.46
3.255
Im pretty sure this is correct. Correct me if I'm wrong. Hope this helps.
Step-by-step explanation:
Area of trapezium=(b1+b2)*h/2 ( as given in figure)
b1=30in.
b2=36in.
h=20in.
Area=(30+36)*20/2
=660inches²
