What was the beginning number is his account?
let assume x percent of 150 is 39
so
150 × x % = 39
150 × x/100 = 39
x = 39×100/150 = 26 % answer
I have no clue it’s blurry
Answer: 16.07%
Step-by-step explanation:
Step 1: We make the assumption that 56 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100% = 56.
Step 4: In the same vein, x%=9.
Step 5: This gives us a pair of simple equations:
100=56(1).
x%=9(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% = 56
--------- ----
x% 9
Step 7: Taking the inverse (or reciprocal) of both sides yields
x% = 9
----- ----
100% 56
x = 16.07%
Therefore, 9 is 16.07% of $56.
Answer:
16 cm
Step-by-step explanation:
Suppose that <em>x</em> is the original width. If that original width is enlarged by a scale factor 5/2 that means that <em>x</em> is multiplied by 5/2 and after that multiplication we obtained new width, 40 cm.
Therefore,
x*(5/2) = 40
We multiply the equation by 2 and obtain:
x*5 = 40*2
5x = 80
Now we divide the equation by 5 and obtain:
x = 80/5
x = 16
We obtained that <em>x</em>, the original width was 16 cm
