The sum of two consecutive integers is 51. What are the numbers?
2 answers:
x is the 1st integer
x + 1 is the 2nd integer
x + (x+1) = 51
x + x + 1 = 51
2x + 1 = 51
subtract 1 to both sides
2x + 1 - 1 =51 -1
simplify
2x = 50
divide both sides by 2
2x/2 = 50 /2
simplify
x = 25
x + 1 = 25 +1 = 26
Answer: the numbers are 25 and 26
proof: sum of two consecutive integers is 51
25 + 26 =51
<span> OK
x + x + 1 =51
2x +1 =51
2x =50
x=25
The two numbers are 25, and 26.

A reflection across the x-axis has the rule:
(x,y)→(x,-y).
Then:
- A(-1,-1)→A'(-1,1),
- B(0,1)→B'(0,-1),
- C(4,2)→C'(4,-2),
- D(6,0)→D'(6,0),
- E(3,-3)→E'(3,3).
Answer: the vertices of the image are A'(-1,1), B'(0,-1), C'(4,-2), D'(6,0) and E'(3,3).
