Answer:
12
Step-by-step explanation:
negative times a negative equals a positive.
so, 6 times 2 is 12.
Answer:
The expressions for the payment made to Mary are,
(Monday) 90 = 15m + b
(Tuesday) 62 = 8m + b
where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.
The equation that represents Mary's earning is
y = 4x + 30
For 20 students,
y = 4(20) + 30 = 110
For Lisa's earnings,
y = 8x + 15
Substituting 20,
y =8(20) + 15 = 175
Thus, Lisa would earn more than Mary by $65.

Answer:
2.22 km
Step-by-step explanation:
Assuming initially both were at the same point ...
Distance from Rico = 5.98 km.
Distance from Josh = 8.2 km in the same direction.
If they were going in the same direction, then the final distance between the two can be written as follows:
d = 8.2 - 5.98 = 2.22 km
After 20 minutes, Rico and Josh were 2.22 km away. of distance between them.
Let the third angle of the triangle be y.
y + 64° + 45° = 180° (angle sum of triangle is 180°)
x + y = 180° (angle of a straight line is 180°)
Notice that they both equal 180°. This means that they are the same thing, hence:
y + 64° + 45° = x + y
Since y = y, it is not necessary to write them down. Remove y from both sides of the equation:
64° + 45° = x
Surprise! exterior angle = sum of interior opposite angles.
I hope this clears up any confusion you might have. If not, feel free to leave a comment with your question.
