If the family decides to fly, they know that they will need a rental car for at least part of their trip. Gabriela and Luis esti

mate a budget of $315 for rental car expenses. One rental car company charges $55 per day and $35 in taxes and fees. They also estimate that they will spend $15 per day on gas. Gabriela wrote the equation (55d+35)+15d=315 to determine the number of days the family can rent a car from this company.
How many days could the Morales family rent a car if they choose this rental car company with their estimated budget?

Answer:

The answer is 4

Step-by-step explanation:

Remove the parentheses

55d + 35 + 15d = 315

Collect the like terms

70d + 35 = 315

Move the constant to the right

70d = 315 - 35

Subtract the numbers

70d = 280

d = 4

AB = 3 + x
ICE Princess25 [194]

The given quadrilateral ABCD is a parallelogram since the opposite sides are of same length AB and DC is 4 and AD and BC is 2.

<u>Step-by-step explanation</u>:

ABCD is a quadrilateral with their opposite sides are congruent (equal).

The both pairs of opposite sides are given as AB = 3 + x , DC = 4x , AD = y + 1 , BC = 2y.

  • AB and DC are opposite sides and have same measure of length.
  • AD and BC are opposite sides and have same measure of length.

<u>To find the length of AB and DC :</u>

AB = DC

3 + x = 4x

Keep x terms on one side and constant on other side.

3 = 4x - x

3 = 3x

x = 1

Substiute x=1 in AB and DC,

AB = 3+1 = 4

DC = 4(1) = 4

<u>To find the length of AD and BC :</u>

AD = BC

y + 1 = 2y

Keep y terms on one side and constant on other side.

2y-y = 1

y = 1

Substiute y=1 in AD and BC,

AD = 1+1 = 2

BC = 2(1) = 2

Therefore, the opposite sides are of same length AB and DC is 4 and AD and BC is 2. The given quadrilateral ABCD is a parallelogram.
