Hannah is 1 year old today.
Step-by-step explanation:
Let,
Hannah = x
Biff = y
According to given statement;
y = x+25 Eqn 1
In four years;
y+4 = 6(x+4) Eqn 2
Putting value of y from Eqn 1 in Eqn 2;
Dividing both sides by 5
As x is age of Hannah, therefore,
Hannah is 1 year old today.

Answer:
The range of heights of the cheerleaders is the interval [58, 74)
All real numbers greater than or equal to 58 inches and less than 74 inches
Step-by-step explanation:
we have
Divide the compound inequality into two inequalities
-----> inequality A
-----> inequality B
Solve inequality A
Subtract 28 both sides
Divide by 4 both sides
Rewrite
Solve the inequality B
Subtract 28 both sides
Divide by 4 both sides
therefore
The range of heights of the cheerleaders is the interval [58, 74)
All real numbers greater than or equal to 58 inches and less than 74 inches
