Question: What is 35 percent of 40?

Percentage solution with steps:

Step 1: Our output value is 40.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$40=100\%$40=100%​.

Step 4: Similarly, $x=35\%$x=35%​.

Step 5: This results in a pair of simple equations:

$40=100\%(1)$40=100%(1)​.

$x=35\%(2)$x=35%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

$\frac{40}{x}=\frac{100\%}{35\%}$
40
x​=
100%
35%​​

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{40}=\frac{35}{100}$
x
40​=
35
100​​

$\Rightarrow x=14$⇒x=14​

Therefore, $35\%$35%​ of $40$40​ is $14$ B. 14%

frozen [14]

Answer:

x = -6; the number is -6!

Step-by-step explanation:

This is a somewhat wordy question, but it is actually easy to solve once you write it down!

It should look like this:

5x-2=7x+10

See? It's simple! Now we just solve from there.

5x-2=7x+10\\-2x-2=10\\-2x=12\\x=-6

vladimir1956 [14]
Y+9x-2=8
That's the answer because y=-5 as yku said so to make an equation yiu could use that and you already solved it so it's Y plus 9 multiplied by -2 is equal to 8 :)
