Statement Reason
1.∠4 is an exterior angle of ΔABC Given
2.∠3 and∠4 form a linear pair Linear pair theorem
3.∠3 is supplementary to ∠4 Property of supplementary angle
4.m∠3+m∠4=180° Definition of supplementary angle
5.m∠1+m∠2+m∠3=180° Triangle sum theorem
6.m∠1+m∠2+m∠3=m∠3+m∠4 From step 4 and 5
7.m∠1+m∠2=m∠4 Subtraction rule
Y=50+35.95x
x is how many months you have it
y is how much you pay total

Answer:
The mother is 30 and the daughter is 6
Step-by-step explanation:
When solving for this, you can derive the equations
x=5y and x+6= 3(y+6)
x= mother and y= Daughter
Solve the equations by substituting the first equation into the places of x in the second equation to get the value of x. Next, pug in the value of x and solve for y.
