Answer:
a) x+3=19
Step-by-step explanation:
a)
x is the age of Ronald , Collin is three years older than Ronald , so if we add up x(Ronald's age) and 3(the difference between both of their ages), we would get Collin's age(19) . That is the explanation for this equation.
b)
x+3=19
x=19-3
x=16
thus , x is 16 , in other words , Ronald's age is 16.
Answer:
80=h
Step-by-step explanation:
Multiply all terms by the same value to eliminate fraction denominators
4x60=4x3h/4
Then you get :
240=3h
Divide both sides of the equation by the same term
240/3 and 3/3 that means the 3 cancels out
Simply the fraction and your answer is 80

Step-by-step explanation:
Answer:
a
Step-by-step explanation:
you see triangle DEF is equal to triangle FGH
you write down on the way of triangle DEF formed
you write down on the way of triangle FGH formed.
It has to be the same way.
so plug in the choices
b c and d are the same ways
but a didn`t
First combine like terms.
4n-2n = 2n
now it's a one step equation:
2n=18
divide both sides by 2
n=9
