Answer:
3 hours
Step-by-step explanation:
Let the number for hours afterward be represented as: x
The veteran tutor charges $15 for the first session plus $60 per hour afterward.
This is expressed as
$15 + $60 × x
15 + 60x
The new college graduate charges $45 for the first session plus $50 per hour afterward.
$45 + $50 × x
45 + 50x
The number of hours these two must tutor in order to earn the same amount of money is calculated as:
Veteran tutor = New college graduate tutor
15 + 60x = 45 + 50x
60x - 50x = 45 - 15
10x = 30
x = 30/10
x = 3 hours
Therefore, the number of hours these two must tutor in order to earn the same amount of money is 3 hours
Congruent sides, so isosceles triangle. When we have an isosceles triangle the bisector of angle A is a perpendicular bisector of BC with foot D. So x=ADB=90 degrees.
Angle B is 47 degrees and angle y=BAD is complementary, the other acute angle in a right triangle.
y = 90 - 47 = 43
Answer: x=90, y=43
