Let F be the father's current age, and E be Evie's current age.
F = E + 36 this is the current relation between the ages
F + 3 = 5(E + 3) this the relationship in 3 year (hence the + 3)
Then solve by substituting one equation into another:
(E + 36) + 3 = 5(E + 3)
E + 39 = 5E + 15
24 = 4E
6 = E
Evie's current age is 6.
Answer:
30 or 20 something
Step-by-step explanation:
Answer:
a = 4, b = 
Step-by-step explanation:
Use any ordered pairs of points from the table.
Substitute into the equation and solve for a and b, that is
Using (0, 4), then
4 = a
= a
Hence a = 4
Using (2, 1), then
1 = 4
( divide both sides by 4 )
b² = 
( take the square root of both sides )
b =
Equation is
y = 4
Side DF is congruent (the = and ~ symbol) to side DE
