dime = 0.10 nickle = 0.05 (1) 0.10d + 0.05n = 6.05 (2) 2x 0.10d + 0.05(n-10)=9.85 0.20d + 0.05n - 0.5 = 9.85 0.20d + 0.05n = 10.35 To make things easy, I'll multiply everything by 100 (1) 10d + 5n = 605 (2) 20d + 5n = 1035 (1) 5n = 605 - 10d n = 121 - 2d (2) 5n = 1035 - 20d n = 207 - 4d 121 - 2d = 207 - 4d 121 + 2d = 207 2d = 86 d = 43 43 Dimes
There is an acronym which mathematicians use called BODMAS. It stands for:Brackets Of Division Multiplication Addition Subtraction.This tells us the order in which to perform calculations. As your typed question has not specified (by using brackets) that we must deviate from the order, we must assume that your question looks like:150 = d2 / 25 + 4d - 250.Therefored2 / 25 + 4d = 150 + 250d2 / 25 + 4d = 400d2 + 100d = 10,000d2 + 100d - 10,000 = 0We have now written this equation in the form of a quadratic.This will prove difficult to factor and so the easiest way to now solve this is to use the quadratic formula which is:For Ax2 + Bx + C = 0 thenx = (-b plus or minus (b2 - 4ac)1/2) / 2aSubstituting in our values for d2 + 100d - 10,000 = 0 gives us:d = (-100 plus or minus (1002 - 4 * 1 * -10,000)1/2 / 2 * 1d = (-100 plus or minus 50,0001/2) / 2d = 61.803 (to 3 decimal places) & -161.803(to 3 decimal places).(Note 1: x1/2 means "the square root of x".)(Note 2: Should your question, for example, look like 150 = d2 / (25 + 4d - 250) then your answer will be different, but you have not specified it does and so we must assume it is as solved above).
i think it is where 2d is flat 3d looks like you can touch it but you cant and 4d is where you can see it and physically touch it
A quotient is the result of division. (7 - d)/5 will lead to a quotient.
Write the equation of the given line in standard form: y = mx + c so: 3y = 4x - 7 or y = 4/3x - 7/3 The slope of the given line is 4/3. The slope of the line perpendicular to it is the negative reciprocal (change the sign and flip the fraction over). ie the perpendicular has slope -3/4 So the equation of the perpendicular is of the form y = -3/4x + d or 4y = - 3x + 4d or 3x + 4y = 4d. To evaluate the value of the constant d (or 4d) you will need one point on the perpendicular line. Substitute the coordinates of that point for x and y in the above equation and you've got 4d.
3c - 4d = 6d + 4c Subtract 4c from both sides: -c - 4d = 6d Add 4d to both sides: -c = 10d or c = - 10d
10d - 6 = 4d - 15 - 3d10d - 6 = d - 159d = -9d=-1
4d + 7 = -15 so 4d = -22 so that d = -5.5
d = 2
It is an equation and the value of d is 2
Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
It is a linear equation in one unknown, d.
8 - 4d = 12-4d = 4d = -1
4d-2 equals 6b-4
4(9)-11=25 2(9)+7=25 d=9
D + 3D = 240 4D = 240 Divide both sides of the equation by 4: D = 60
