Answer:
<em>y=-6</em>
Step-by-step explanation:
<em>Geometric Sequences</em>
Any given sequence is said to be geometric if each term can be obtained as the previous term by a constant value called the common ratio.
or equivalently
Looking closely at the sequence 2, y, 18,-54, 162 we can try to find out if it's a geometric sequence or not. We compute the possible common ratios
and we see they both result -3. If we use r=-3 and try to find the second term (y), then
y=2*(-3)=-6
Now we compute the third term: (-6)(-3)=18
Since we got the third term as given in the original sequence.
So y=-6

Step-by-step explanation:
Known facts
- Marisol burned 670 calories
- Ling burned x fewer calories than Marisol
Setting up the equation
# of calories that Ling burned = Marisol's calorie - x = 670 -x
Hope that helps!
Answer:
8
Step-by-step explanation:
RT=10 it is on number A
XY=18 it is on number B
YZ=12 it is on number C
So, I think that no D 8 is in last so that is the answer.
Hello there,
So he has two cars. Each comes in 3 colors and either automatic or standard.
So let's say he has got the convertible. He can get the white automatic or a white standard. Same as red and blue. So there are 6 choices for 1 car.
So let's say he has got the hatchback. He can get the blue with automatic or standard. That goes with white and red as well.
So if he has 2 cars and 6 choices for 1 car he has 12 choices to choose from.
Hope this helped!
3.33 or 1/.3 is the answer
