1 answer:
<u>ANSWER</u>
A. (4,12)
<u>EXPLANATION</u>
The equations are:
and
To eliminate a variable we make the coefficients of that variable the same in both equations.
It is easier to eliminate x.
We multiply the first equation by 2 to get:
We add equations (2) and (3).
Divide both sides by 23
Put x=4 into equation (1).
The solution is (4,12)

Answer: If a group wants to take a 3 hour ride they should choose Hobbs Mules.
Step-by-step explanation:
First figure out how much a 3 hour ride at McGee Mules would cost. Do this by setting up a proportion, then solving it.
Numerator = Time Denominator = Cost
=
42 x 3 = 126/1 = 126 So a 3 hour ride with Mcgee should cost $126.
Next figure out how much a 3 hour ride at Hobbs Mules would cost by doing the same thing.
=
80 x 3 = 240/2 = 120 So a 3 hour ride with Hobbs should cost $120.
In conclusion, The group should choose Hobbs because they price is $6 cheaper.
Hello!
The statement that is true about the three quadrilaterals is the first one:
____________________________________________________________
Option #2 is incorrect because although E and F are similar, they are not congruent. They do not have the same size.
Option #3 is also incorrect because, again, D and E are similar, but they are not congruent.
Option #4 is not correct because it says that "F and D are similar but not congruent." This is not true since they are the same shape and size. Only their orientation is different, which makes them congruent.
