Just divide the input by 4.

f(x) = x/4

63 is 75% of what number?<br>  <br> Enter your answer in the box.
Viefleur [7K]
75% of x = 63 

<span>75/100 * x = 63 </span>

<span>So dividing by 75 / 100 on both sides </span>

<span>x = 63 / 75 / 100 </span>

<span>x = 63*100/75 </span>
<span>x = 84 </span>
<span>The number is 84 </span>

<span>So 75% of 84 = 63! </span>

<span>Hope that helps!</span>

Please help i dont understand

<em><u>Question:</u></em>
<em>Mrs. Magdalino kept records on how much she spent on gasoline and the maintenance of her car.  She found that it cost $485 to drive 500 mi in a month.</em>
<em>a)  Find the cost per mile.  Write an equation that relates the cost c for gasoline and maintenance of a car to the number of miles m the car is driven.</em>
<em>b)  Use the equation to find the cost for driving 1200 miles.</em>
<em>c)  About how many miles are driven for a cost of $820?</em>

<em><u>Answer:</u></em>
a)
$485/500mi = <u><em>$0.97/mi</em></u>

c = cost
m = miles driven

cost per miles driven = cost / mile driven = <u><em>c/m</em></u>

b)
(1200 mi)*($0.97/mi) = <u><em>$1164</em></u>

c)
(x miles)*($0.97/mi) = $820

*divide both sides by $0.97/mi

x miles = $820/($0.97/mi)

<u><em>x = 845.36 miles</em></u>

The value of x is?<br> 84<br> 96<br> 132<br> 264<br> HELPPPP!!!!
Alexandra [31]

The 3 outside angles of a triangle need to equal 360 degrees.

To find X, subtract the 2 outside angles shown from 360.

X = 360 - 130 - 134 = 96

The answer is 96

Who knows how you do you this??
Monica [59]
Hi!
Okay, so this actually isn't too bad! (For number 5) Just add the negative x over to get 2x. Then subtract 2 over to get -10. Then divide by 2 (-5) and you're done! For the rest, do the same thing. Get the x's on one side, get the regular numbers on the other, and divide! Hope that helped!

marin [14]

Answer:

an-1-9

25n-1-9

25n-10=0

25n=0+10

25n=10

divide both sides by 25

25n/25 =10/25

n=2/5
