The solution
m = s + 5
<span>m - 4 = (3s) - 3 </span>
<span>(s + 5) - 4 = 3s - 3 </span>
<span>s + 1 = 3s - 3 </span>
<span>s = 3s - 4 </span>
<span>-2s = -4 </span>
<span>s = 2 </span>
<span>m = 7 </span>
<span>Check this: </span>
<span>m - 4 = 3s - 3 </span>
<span>7 - 4 = 3(2) - 3 </span>
<span>3 = 6 - 3 </span>
<span>3 = 3 </span>
<span>So Sandy is 2 and Megan is 7.</span>
Answer:
1074.5 or 1074 1/2
Step-by-step explanation:
I'm pretty sure that is supposed to be a division sign, right? For future reference, use the "/" symbol.
It is already given in the question that 2 iodine tablets are required to disinfect 1 quart of stream water. The thing that needs to be found is the number of tablets required to disinfect 4 quarts. As can be seen in the question, the information's provided are enough to get to the desired answer.
Then
Number of tablets required to disinfect 1 quart of stream water = 2
Number of tablets required to disinfect 4 quart of stream water = 2 * 4
= 8
So 8 iodine tablets are required to make 4 quart of stream water drinkable.

Firstly we must know what complex Number is .
Complex number - The number in the form of a + bi ,where a is real part and bi is Imaginary part is called a complex number . Also here value of i ( read as iota ) is √-1 . It can't be represented on the number line and is represented on the Argand Plane .
So , here the complex number given to us is 7 + 9i .
So , it can be written as ,
= 7 + 9i .
= 7 + 9√-1 .
= 7 + √9 × √9 × √-1 .
= 7 + √ 81 × -1 .
= 7 + √-81 .
