Answer: In order to save money for a 1 day rental with plan B, the number of miles must be greater than 153.84 miles
Step-by-step explanation:
Let x represent the number of miles driven with either plan A or B.
Plan A: 30 dollars per day and 13 cents per mile. It means that the cost of renting the car or one day and driving x miles is
30 + 0.13x
Plan B: 50 dollars per day with free unlimited mileage. It means that the cost of renting the car or one day and driving x miles is 50
In order to save money for a 1 day rental with plan B, the number of miles would be
50 < 30 + 0.13x
50 - 30 < 0.13x
20 < 0.13x
0.13x > 20
x > 20/0.13
x > 153.84 miles
Let assume
X for ice cream cones
Y for sundaes
X+Y=172
X=172-Y……..*
1.10X+2.35Y=294.20
Substitute * in the above equation
1.10(172-Y)+2.35Y=294.20
189.2-1.10Y+2.35Y=294.20
1.25Y=294.20-189.2
1.25Y=105 divide both sides by 1.25
Y=84
The substitute Y value in * equation
X=172-84
X=88
Therefore
88 ice cream cones and 84 sundaes were sold!!
Answer:
Option A is correct because sum of m<2 and m<3 are complementary. So m<2+m<3 =90° .
Step-by-step explanation:
Given: <2 and <3 are complementary angles.
Definition of complementary angles says if two angles sum is equal to 90 degrees then they are called complementary angles.
Statement Reason
1.<2 and <3 are complementary 1. Given
2. m<2+m<3 =90° 2. Definition of complementary <s
3. m<1= m<3 3. Given
4. m<1+m<2= 90° 4.Substitution property of =
5. <1 and <2 are complementary 5. Definition of complementary <s.
Option A matches with the given. We can not use addition properties of equality for statement 2 so, other options are incorrect.
So, according to the given options A is correct.
