A rental car company charges $30.05 per day to rent a car and $0.10 for every mile driven. Anthony wants to rent a car, knowing
Annette [7]

Answer:

Three days at the most.

Step-by-step explanation:

First you must see how much money he spends on driving, 75 x 0.10 = 7.5. Subtract that from 120 to get 112.5. He has that much money left. Now you will divide 112.5 by 30.05. 112.5/30.05 = 3.74376039933. Simplify to get 3.

(also, he will have 22.35 dollars left)

"If three angles and two sides of two triangles are congruent, are the triangles congruent? Why or why not?"
Anettt [7]

Answer:

yes

Step-by-step explanation:

because the corresponding angles are congruent, the triangles are congruent through CPCTC. If two sides are congruent and an included angle, then the triangles are congruent through the SAS postulate. And if two sides and a non-included angle are congruent then the triangles are congruent through the AAS postulate. Any way of looking at this proves congruency through various postulates, therefore the trianlges are congruent.

Hunter is 35 years older than Andrew. After 5 years Hunter will be twice Andrew's age. Find the present age of both.
Anettt [7]

Answer:

Andrew is 30 years old. Hunter is 65 years old.

Step-by-step explanation:

we can set up 2 equations:

h = 35 + a

h+5 = 2(a+5)

Solve for h in the second equation.

h + 5 = 2a + 10; h = 2a + 5

now set the 2 equations = to each other

2a + 5 = 35 + a

solve for a by combining like terms

a + 5 = 35

a = 30

so Andrew is 30 and Hunter is 35 + 30 = 65.

Sp in 5 years Andrew is 35 and Hunter is 70 (twice A's age)
