Answer:
1,4
Step-by-step explanation:
The anwser is 1,4
Call (F) the age of the father and (J) the age of Julio
The F & J are related in this way: F=4J
Now you have a restriction in the form of inequality: The sum of both ages has to be greater or equal than 55.
Algebraically that is: F + J ≥ 55
You can substitute F with 4J to find the solution for J:
4J + J ≥ 55
5J ≥ 55
Now divide both sides by 5
5J/5 ≥ 55/5
J ≥ 11
That Imposes a lower boundary for the value of J of 11, meaning that the youngest age of Julio can be 11
Answer:
D A = (1/2) (y₂ - y₁)(x₃ - x₁)
Step-by-step explanation:
b = (y₂ - y₁)
h = (x₃ - x₁)
A = (1/2)bh
A = (1/2) (y₂ - y₁)(x₃ - x₁)
General form is ax^2 + bx + c = 0
so comparing the equation in the question to this we get:-
a = 1, b = -3 and c = -2 Answer
Answer: The entire trip is 62.5 miles
Step-by-step explanation:
25 miles = 0.4x
Divide both sides by 0.4
25/0.4 = 62.5 miles
