58=7/4x
Multiply both sides by 4 so the fraction cancels out:
232=7x
Divide both sides by 7:
x=33.14 (rounded)
Hope this helps :)
9. -1,07, 1/2. 3........it is all I could see
10. -V25= -5
-5, -4,3, 0, V15, 4,2
Answer: a = 3.5
Step-by-step explanation:
14=4a
divide both sides by 4
14/4 = 3.5
4a/4 =1a or a
so a= 3.5
We are given the first term and the common ratio, this means they belong to a geometric series.
For the given series:
![a_{1}=-3 \\ r=1.5](https://tex.z-dn.net/?f=a_%7B1%7D%3D-3%20%5C%5C%20%0Ar%3D1.5%20)
Each term of the geometric series is obtained by multiplying the previous term by common ratio.
So the next terms will be:
-4.5, -6.75, -10.125, -15.1875, -22.78125
The general formula for the G.P would be:
![a_{n}=-3(1.5)^{n-1}](https://tex.z-dn.net/?f=%20a_%7Bn%7D%3D-3%281.5%29%5E%7Bn-1%7D%20%20)
On plotting the series, the result will be like this:
Answer:
30%
Step-by-step explanation:
The answer is off by 30%, as the scale is off by 3 pounds. 3/10=30
