Answer:
Step-by-step explanation:
Distributive property of equality, here we are performing opposite operation, which is factoring:
- 60 + 12x =
- 6*10 + 6*2x = Show both terms as a factor of 6
- 6(10 + 2x) Factor out 6
Answer:
The common difference (or common ratio) = 0.75
Step-by-step explanation:
i) let the first term be 
= 80
ii) let the second term be 
= . r = 80 × r = 60 ∴ r = 
= 0.75
iii) let the third term be 
= . r = 60 × r = 45 ∴ r = 
= 0.75
iv) let the fourth term be 
= . r = 45 × r = 33.75 ∴ r = 
= 0.75
Therefore we can see that the series of numbers are part of a geometric progression and the first term is 80 and the common ratio = 0.75.

Step-by-step explanation:
Above I have the probability chart. Their are 36 students so that’s the ’out of’ thing I used, for instance, Answer A: the probability of you meeting a student who only eats lunch is: 16 out of 36 (16 students who eat lunch, while 36 altogether.)
I wish you luck on this homework!!!!
Answer:
The problem in the first statement is that it does not say that the lines must be in the same plane.
Suppose in a 3D coordinate axis two lines as:
z = 0, y = 0 (this is the x-axis)
y = 1, x = 0 (this line is parallel to the z-axis but one unit above).
Those two lines are not parallel, and also never meet, so the definition is wrong.
The actual definition should be:
"Parallel lines are two lines that lie on the same plane and never meet"
B: The undefined terms are point, line, plane,...
An example can be "Plane", because if our lines do not lie on the same plane, then we can not use the concept of "parallel lines".
Answer:
36 square feet
Step-by-step explanation:
To get the answer you need to find the area of the triangle and subtract area of the rectangle.
7*12/2 = 42
42 - 3*2 = 36
