Answer:
45
Step-by-step explanation:
Let the original number be xy where y is unit and x is tens hence original number is 10x+y When reversed, the new number is yz hence 10y+x
We know that the original number plus 9 is the reversed number hence
10x+y+9=10y+x
9y-9x=9 which when simplified we obtain that
y-x=1 equation 1
Originally, we are told that the sum of x and y is 9 hence
y+x=9 equation 2
Solving equation 1, it means y=x+1
Substituting the above into equation 2
x+1+x=9
2x=9-1
2x=8
x=8/2=4
Since y=x+1 then y=4+1=5
Therefore, the original number, xy is 45
Answer:
m = 0
Step-by-step explanation:
Slope Formula: 
Simply plug in the coordinates into the formula:
m = (-3 + 3)/(4 - 6)
m = 0/-2
m = 0

Hence the equation would be
(X+2/3)(X-5)=0
(3X+2)(X-5)=0
Answer : 
The volume of the prism:
V = L x W x H,
where L is the length, W the width and H the height.
We can find the volume of the entire figure by adding together the volumes of two smaller figures ( 2 prisms ).
The 1st one has dimensions: 2, 2, 7 and the 2nd has dimensions 2, 3, 8.
Answer:
B . ( 2 x 2 x 7 ) + ( 2 x 3 x 8 )
