### how do you know what formulas to use when solving for two unknowns

Problem: how do you know what formulas to use when solving for two unknowns I am trying to solve a word problem and still have two unknowns and don't know where to go from there. the problem states: A 10kg object on a 26 degree inclined plane. What are the objects weight and the normal force exerted on the object by the inclined plane? I don't understand what I'm missing. :( An object sitting on a flat surface exerts force straight down, vertical. An object on an inclined plane exerts force in both a vertical and a horizontal direction. You multiply the weight by the cosine of the angle to determine the vertical force, and multiply the weight by the sine of the angle to determine the horizontal force.

### solve word problem using polynomials

Problem: solve word problem using polynomials Joe has a collection of nickles and dimes worth \$2.15 If the number of dimes was doubled and the number of nickles was increased by 28, the value of the coins would be \$4.65. How many nickles and dimes does he have? Let's say he has n nickles and d dimes. 0.05n + 0.10d = 2.15 The problem proposes to increase d to 2d and increase n to n + 28. 0.05(n + 28) + 0.10(2d) = 4.65 We have two equation to work with. Let's multiply both equations by 100 to eliminate the decimals. 100(0.05n + 0.10d) = 2.15 * 100 5n + 10d = 215 100(0.05(n + 28) + 0.10(2d)) = 4.65 * 100 5(n + 28) + 10(2d) = 465 We need to expand this second equation. 5(n + 28) + 10(2d) = 465 5n + 140 + 20d = 465 5n + 140 + 20d - 140 = 465 - 140 5n + 20d = 325 Here's what we have: 1) 5n + 10d = 215 2) 5n + 20d = 325 We can immediately eliminate the n by subtracting equatioin 1 from equation 2.    5n + 20d = 325 -(5n + 10d = 215) ------------------------           10d = 110 10d = 110 10d/10 = 110/10 d = 11 This tells us that Joe currently has 11 dimes. Let's use equation 1 directly above to solve for n. 5n + 10d = 215 5n + 10(11) = 215 5n + 110 = 215 5n + 110 - 110 = 215 - 110 5n = 105 5n/5 = 105/5 n = 21 This one tells us that Joe currently has 21 nickels. We need to check the two numbers against what the problem originally stated. 0.05n + 0.10d = 2.15 0.05(21) + 0.10(11) = 2.15 1.05 + 1.10 = 2.15 2.15 = 2.15 Verified! Answer: Joe has 21 nickels and 11 dimes.

### i need to know how to figure out word problems dealing with solving mph and minutes

i need to know how to figure out word problems dealing with solving mph and minutes the question is 50mph between two towns and they arrived in 25 minutes. im not looking for an answer just the formula to solve so i can study it   (mph) is a mile per hour → this a velocity (speed) so if talking about two towns mean that there will be distance to travel in mile(s). 25 min is the time that used to travel this two town.   as you are going to examen the velocity (mph or mile / hour) this mean Velocity = mile(distance) / hour (Time)   If you will be asked for Distance then Distance = Velocity x Time   If you are asked for time then Time = Distance / Velocity     This is whar you are going to need in solving problem like this.   Remember that Jesus loves you.  Know Him in the Bible God Bless

### what kind of viva question can be asked by a teacher about the course of algebra by a masters students

Type of question:  "How can your subjects (algebra and calculus) best be explained progressively to children and young people to enable them to develop their understanding gradually to grasp the principles involved in these abstract subjects, so that they can demonstrate their understanding in applying it in a practical way to everyday problems?" "How can such learning be communicated so as to be a fun thing, rather than cold, formal and analytical, as is often taught?" (Children will often attempt to understand the subjects by learning by rote formulas and the like without any comprehension of how their understanding can be applied. This makes the subjects boring for them when, with the right teaching techniques, it could be fun! If children can be taught at every step of the way in terms of what they already fully understand, they will enthusiastically and gradually develop their understanding of more and more complex, abstract topics.) If you're actually looking for a problem to set students, there are many examples, but the ideal problem is one that gets students to apply their understanding of mathematics in a practical way. Combining geometry with algebra, is one way. Choosing a problem that tests students' understanding of the formula for solving quadratic equations, or trigonometric identities, or rules like the sine and cosine rules, or simultaneous equations, etc., without specifically stating what methods to apply in solving the problem, is a good way of discovering students' mathematical ability in practical application. Such problems could be presented as word problems and could be expressed concisely to appear simple, but nevertheless demanding on the intellect and comprehension.

If Kelling Community College purchased 120 boxes for a total of \$1234.80 how many boxes of each did they purchase? x = number of boxes of Pilot pens y = number of boxes of Bic pencils x + y = 120 17.99x + 7.49y = 1234.80 x + y = 120 y = -x + 120 17.99x + 7.49y = 1234.80 17.99x + 7.49(-x + 120) = 1234.80 17.99x - 7.49x + 898.80 = 1234.80 10.5x + 898.80 = 1234.80 10.5x + 898.80 - 898.80 = 1234.80 - 898.80 10.5x = 336 10.5x/10.5 = 336/10.5 x = 32 y = -x + 120 y = -32 + 120 y = 88 17.99x + 7.49y = 1234.80 17.99(32) + 7.49(88) = 1234.80 575.68 + 659.12 = 1234.80 1234.80 = 1234.80 Answer: 32 boxes of Pilot pens, 88 boxes of Bic pencils

### how to solve word problems

Problem: how to solve word problems To buy both a new car and a new house, Tina sought two loans totaling \$318,338.
