Answer- 70
38+x+x+2= 180
Collect like terms
40 +2x=180
Bring 40 to the other side and subtract
2x=140
Divide by 2 to get x alone
X=70
The given sequence is a geometric sequence with a common ratio of 3.
<h3>
</h3><h3>
Which type of sequence do we have here?</h3>
A geometric sequence is a sequence where the quotient between any pair of consecutive terms is a constant, called the common ratio.
Here we have the sequence:
3, 9, 27, ...
The quotient between the first two terms is:
9/3 = 3
The quotient between the third and second terms is:
27/9 = 3.
So yes, we conclude that this is a geometric sequence, where the common ratio is 3.

Answer:
9 of each
Step-by-step explanation:
9 x 10= 90
9 x 5= 45
9 x 1= 9
90 + 45 + 9= 144, now add a decimal
Answer:
y = 93
Step-by-step explanation:
x = y
180 - (45 + 42) = x = y
180 - 87 = x = y
93 = x = y
93 = y
