You just have to multiply the numerator and denominator by the same number.
Hope it helps.
Can you <em><u>please please</u></em> choose mine as the brainliest answer.
I need it for me to get to the next level.
I can see this is a pattern.. 5,5,0,1,1,5 etc.

Answer: <em>f(x) </em>= 21 .The output is 21 when the input is 5.
Step-by-step explanation:
f(x) = 4x+1 Substitute the input, 5, for x on the right side <em> f(x) is the equivalent of y, the output you are looking for</em>
<em>f(x) </em>= 4(5) + 1
<em>f(x) </em> = 20 +1
<em>f(x) </em>= 21
14. 32 out of the 125 people surveyed preferred Company B. If the same proportion holds for the larger sample, we expect
... (32/125)×750 = 192 . . . . people would prefer Company B
15. There are a total of 45 marbles in the bag, of which 28 are NOT blue. The probability of drawing a NOT blue marble is 28/45.
16. We can desginate the point where the lines meet as O. Angles NOK and MOL are vertical angles, so are equal. The diagram tells you the measure of NOK is 90° + 15° = 105°, so that is the measure of (5x)°. The value of x is
... 105/5 = x = 21
17. Division by a fraction is the same as multiplication by its inverse.
