Answer:
18%
Step-by-step explanation:
Step 1: We make the assumption that 90 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%=90
Step 4: In the same vein, x%=16.2
Step 5: This gives us a pair of simple equations:
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
Step 7: Taking the inverse (or reciprocal) of both sides yields
Therefore, 16.2 is 18% of 90
Answer:
t = 108
Step-by-step explanation:
t - 27 =
t + 21 ( subtract
t from both sides )
t - 27 = 21 ( add 27 to both sides )
t = 48 ( multiply both sides by 9 )
4t = 432 ( divide both sides by 4 )
t = 108
