https://www.mathhomeworkanswers.org/259234/how-to-solve-equation?show=259248#a259248
All you do is divide 3 both sides. 3/3 = 1 but don't use that. You get the variable by itself.<br />

18/3 = 6. That's all you need for this step.order of operationshttps://www.mathhomeworkanswers.org/259234/how-to-solve-equation?show=259248#a259248Tue, 19 Mar 2019 23:35:12 +0000Answered: How many milliliters of a 3.60 M NaBr solution contain 62.9 g of NaBr?

https://www.mathhomeworkanswers.org/34317/what-is-the-square-root-os-123?show=259139#a259139

https://www.mathhomeworkanswers.org/258939/do-i-have-this-correct-and-where-would-this-be-used?show=258958#a258958
<p style="text-align: justify;">Yes, you are correct.</p>
<p style="text-align: justify;">I haven’t been in education for more than 50 years. I know how you feel. Mathematics has interested me since I was about 12. I like solving problems.</p>
<p style="text-align: justify;">Now to answer your questions.</p>
<ol>
<li style="text-align: justify;">You could have subtracted one equation from the other, because it’s the same as multiplying one equation by -1 and adding; but what you’re really doing is eliminating one variable so that you have one equation and one variable. Therefore you are simplifying the problem.</li>
<li style="text-align: justify;">In the “real world” this type of problem has many analogies. For example, you could be comparing the costs of two items, and want to know the cost of each item when all you have is the quantity of each item and the differences in costs. The same applies if you were trying to find unit cost. This could be important in managing domestic economy or on a larger scale in manufacturing when deciding on sources of raw materials. Systems of equations can involve many variables and there are a number of methods that can be used to solve them (matrices, for example). Plus the use of computers where manual methods are tedious and prone to error.</li>

https://www.mathhomeworkanswers.org/258796/how-do-the-parentheses-affect-the-integer?show=258803#a258803
<p style="text-align:justify">Yes, -(9)³=(-9)³=-729, but -(9)² is not the same as (-9)², because -(9)²=-81 and (-9)²=81.</p>
<p style="text-align:justify">If we write -9=-1×9 then the reason becomes clear. (-1)³×(9)³ is the same as (-9)³.</p>
<p style="text-align:justify">(-1)³=-1 so (-9)³ is the same as -1×(9)³. </p>
<p style="text-align:justify">-1 to an odd power is -1, but -1 to an even power is 1. This is because of the rule about multiplying numbers with signs. Minus time minus is plus, so -1×-1×-1=-1, because any pair of -1’s multiplied together produce 1.</p>
<p style="text-align:justify">In -(9)², the parentheses show what action is to be done first, and this can also be written -(9²). The answer is -81 in each case. But if we put the minus inside the parentheses, then we have (-1)²(9)² which is the same as (-9)² and we have 1×81=81. </p>
<p style="text-align:justify">Parentheses only tell you what to do first and sometimes they can be omitted and you still get the same result. For example, (3)+(4) is the same as 3+4. But 2×(3+4) tells you to add 3 and 4 together then multiply the result by 2; but 2×3+4 tells you to multiply 2 and 3 then add 4 to the result. This could also be written (2×3)+4 without changing the result, because the parentheses are not necessary. PEMDAS tells you in what order you need to do a calculation: and P (parentheses) comes before everything else: work out the contents of the parentheses first, if you can, otherwise apply distributive laws, that is, apply what’s outside the parentheses to each term inside.</p>Pre-Algebra Answershttps://www.mathhomeworkanswers.org/258796/how-do-the-parentheses-affect-the-integer?show=258803#a258803Fri, 08 Mar 2019 10:00:28 +0000Answered: What is 0.6656 ÷ 0.32
