Question

Please answer me fast​

Answer 1

Step-by-step explanation:

Sum of three numbers = 90

x + (x+1) + (x+2) = 90

(x+x+x) + ( 1+2) = 90

3x + (3) = 90 ( Change the position of +3 and

bring it to right side )

3x= 90-3

3x= 87 ( Bring 3 to right side )

x= 87/3

x= 29

Therefore

x= 29

x+1 = 29+1 = 30

x+2 = 29+2=31

I hope this answer would be helpful to you

Answer 2

Answer:

Step-by-step explanation:

9.Let the tree consecutive numbers be x, x+1 and x+2.

Sum = 90

ATQ

x + x+1 +x+2 = 90

3x + 3 = 90

3x = 87

x =  29

The numbers : - 29 , 30 and 31.

So, the numbers are 29, 30 and 31.

10. Let the breadth be x.

Length = 8 + x

Perimeter = 184m

ATQ

2(x + 8+x) = 184m

=) 2(2x + 8) = 184m

=) 4x + 16 = 184m

=) 4(x + 4) = 184m

=) x + 4 = 46

=) x = 42

Length = 8 + 42 = 50m

Hence, the length is 50m and 42m.
