We use equations for geometric sequence. We do as follows:<span>
a(n) = a(1) r^(n-1)
20 = ar^(2-1)
</span>20 = ar<span>
a = 20/r
11.25= ar^(4-1)
</span>11.25 = ar^3
<span>11.25 = (20/r)r^3
r = 0.75
Hope this answers the question. Have a nice day.</span>
Answer:
Step-by-step explanation:
The equation has one solution.
6(x+2)=5(x+7)
6x+12=5x+35
6x+12-5x=35
6x-5x=35-12
x=23
Therefore, the equation has ONE solution.
Answer is D:73
Explanation:180-124=66
66+37=103
180-103=73
To find the slope use the rate of change in y/the rate of change in x or you can use y2-y1/x2-x1
