<span>The
problem wants us to find the number that the 21% is 42.
42 is the 21% of 200
How:
=> 21% = 21 /100
=> .21
In order to get the answer we need to find a number to be multiplied by .21 and
get 42 as result.
=> 50 x .21 = 10.5
=> 100 x .21 = 21
=> 150 x .21 = 31.5
=> 200 x .21 = 42
thus, 42 is the 21% of 200.</span>
Y-5=3-9(y+2). so so u are going to distribute-9 to y and 2 which is -9y-18
so u are going to add like terms 3 and -18 which is -15. so the next step is going to be y-5=-9y-15 so u are going to add 5 to -5 and -15 to balance the equation and u will get -10 . y=-9y -10. since u are multiplying -9 by y so have to expand it y= -9 * y -10. so u have to divide y by y to get y . -9-10= -19 soo y =-19
<h3><u><em>
Answer:</em></u></h3>
x = 15
<h3><u><em>Step-by-step explanation:\</em></u></h3>
Multiply both sides of the equation by 3
3 x 1/3 x X = 3 x 5
Simplify both sides of the equation.
Simplify 3 x 1/3 x X.
1 x X = 3 x 5
Multiply x by 1.
x = 3 x 5
Multiply 3 by 5.
and you get x = 15
