To solve 1/8x = -5 , you will need to multiply both sides of the equation by 8. once you do that you will get the answer:
x= -40
let me know if you have any other questions

1/8x = -5

isolate the x, remember that what you do to one side, you do to the other (because of equal sign)
1/8x(8) = -5(8)

x = -5(8)

x = -40

<u>Note:</u> two positive numbers multiplied or divided = positive answer. One negative and one positive number multiplied or divided = negative answer. Two negative numbers multiplied or divided = positive answer


hope this helps

17% of what number is 3.4
saw5 [17]

Answer:

20

Step-by-step explanation:

We already have our first value 3.4 and the second value 17. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

Step 1 ---> 3.4 = 17% × Y

Step 2 ---> 3.4 = 17/100 × Y

Multiplying both sides by 100 and dividing both sides of the equation by 17 we will arrive at:

Step 3 ---> Y = 3.4 × 100/17

Step 4 ---> Y = 3.4 × 100 ÷ 17

Step 5 ---> Y = 20

Finally, we have found the value of Y which is 20 and that is our answer.

<h3><u>*You can easily calculate 3.4 is 17 percent of what number by using any regular calculator, simply enter 3.4 × 100 ÷ 17 and you will get your answer which is 20*</u></h3>

determine if the sequence is geometric or arithmetic and find the ratio or difference. -1, 6, -36, 216
andrew-mc [135]
The sequence is an geometric progression;
Nth=a₁r^(n-1)
a₁ is the first term=-1
r=ratio=a₂/a₁=6/-1=-6

Nth=-1(-6^(n-1)

NTh=an

a
₁=-1(-6⁰)=-1
a₂=-1(-6¹)=6
a₃=-1(-6²)=-36
a₄=-1(-6³)=216

therefore this serie is rising at an increasing fast speed, it is an geometric progression.
