Simon is 13 years old
Let x be Simon's age
Thus 4 years ago his age was (x - 4) and 2 years from now his age is (x + 2)
Hence 5(x - 4) = 3(x + 2)
distributing both sides gives
5x-20 = 3x + 6
subtract 3x from both sides of the equation
5x - 3x - 20 = 6
2x - 20 = 6
add 20 to both sides
2x = 6 + 20 = 26
divide both sides by 2
x = = 13

Answer:
Length is 182 cm and width is 158 cm.
Step-by-step explanation:
Given:
Perimeter of rectangle table = 680 cm.
Let the width of the table be .
Now according to given length of the table is 24 cm more than the race the width
hence length = .
But perimeter of rectangle = 2(length+width)
Substituting the values we get;
Hence width = 158 cm
Now, length = 24 cm + width = 24 cm + 158 cm = 182 cm
Hence the dimension of table are 182 cm and 158 cm.
Answer:
The missing value is 2
Step-by-step explanation:
A direct variation satisfies the equation .
Since the point (-18, 12) lies on this line, it must satisfy this equation.
Hence the equation of this line is
Now we substitute x=-3 to find y.
Therefore the missing value is 2
