- 1/42 x (21x233y)
Step-by-step explanation:
first convert the expressions (2 3/10x x5/7 x y-2 4/5 x x )
then factor the expression (23/10 x- 5/7 y- 29/6 y- 14/5x )
then collect like terms (1/210 x 483 x - 150 y - 1015 - 588x)
factor the expression (1/210 x 105x 1165y)
Multiply reduce (1/210 x -5 (21x + 233y ))
= -1/42 x (21x233y)
Casey is 18 years old and Ralph is 3 years old.
Step-by-step explanation:
Let,
Age of Casey = x
Age of Ralph = y
According to given statement;
x = 6y Eqn 1
In two years
x+2=4(y+2)
x+2=4y+8
x = 4y+8-2
x = 4y+6 Eqn 2
Putting value of x from Eqn 1 in Eqn 2

Dividing both sides by 2

Putting y=3 in Eqn 1

Casey is 18 years old and Ralph is 3 years old.
