(9/14)*6x = (27/7)x
And that is reduced by 10, then...
27/7x - 10
Answer:
- 28
Step-by-step explanation:
Plug in 7 for x
5 + 7 - 5 x 8
5 + 7 - 40

Hi there!
nearest percentage=64%
<em><u>1.Subtract starting value and final value:</u></em>
<em><u /></em>
<em><u /></em>
<em><u>2.Divide it by the starting value:</u></em>
<em><u /></em>
<em><u /></em>
<em><u>3.Multiply the term by 100:</u></em>
<em><u /></em>
<em><u>·</u></em>
<em><u /></em>
<em><u>4.Round the term:</u></em>
<em><u /></em>

Answer:
x = -3, x = 0 is a extraneous solution
Step-by-step explanation:
Step 1: Cross-multiply
3x² = 4x² + 3x
Step 2: Isolate <em>x</em>'s
0 = x² + 3x
Step 3: Factor
0 = x(x + 3)
Step 4: Find roots
x = 0, -3
Step 5: Double check work
Plug in both to see if they both work. Only x = 0 should be extraneous. We now have our answer!
I'm not good at math but I think is 3f because you'll be multiplying f(unknown #) by 3 so f(x) would be 3f
