If 8b plus 11-3b equals 2b plus 2 what is b?
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
Does an equation have to contain a variable?
An equation does not need variables. 4+5=9 is an equation as is 5+W=9
What is the equation of the horizontal line that passes through the point (9-4)?
Assuming the point is (9, -4), the equation is y = -4.
Is the point 39 a solution of the equation y8x-9?
The expression of y8x-9 has no solution because without an equality sign it can not be considered to be an equation.
What is the equation of the circle with center (2 -9) and radius 7?
Equation of circle: (x-2)^2 +(y+9)^2 = 49
does a=3b+5c+9 equivalent to the equation to a-3b=5c+9?
79
What is 3b equals 9?
It is an equation and the value of b is 3
What is -5c plus 9 and how?
You can't tell a thing about -5c+9 until you know what 'c' is. And every time 'c' changes, -5c+9 changes.
What is Two less than the product of three and a number b is 7?
Set up the equation: 3b-2=7. Solve for b: Subtract 2 from both sides: 3b=9. b=3.
If 3b plus 9 12then b?
If you mean 3b+9 = 12 then b equals 1
What number is equivalent to -9 plus 9?
-9 + 9 = 0 The equation can be written 9 - 9 = 0 The answer is 0 (zero)
What is the value of x if 4bx-5c?
9
What would this mean (In a maths state) 45c/5c?
9
One number is 5 times another if 18 is subtracted from the greater the remainder will be 3 times the smaller Find the numbers?
The numbers are 9 and 45. a = 5b a - 18 = 3b which becomes a = 3b + 18 Therefore: 5b = 3b + 18 18 = 2b b = 9 a = 45
What is nine less than a number is 9?
It is an equation: n - 9 = 9It is an equation: n - 9 = 9It is an equation: n - 9 = 9It is an equation: n - 9 = 9
At what temperature is centigrade equal to Fahrenheit?
The correct answer is of course -40 degrees.Whilst the equations are both linear, if you were to plot them both on the same graph, you would see that the results do intersect (at -40degrees). Another, slightly more geeky, way to get the answer is to use the 2 equations1. F=9/5C +32 ... used to convert from centigrade (Celsius) to Fahrenheit2. C= 5/9(F- 32).... used to convert from Fahrenheit to Centigrade (Celsius)Firstly write the write the equations so that they are equal (C=F), and then we can solve the simultaneous equations. So it looks like this:9/5C+32 = 5/9(F-32). (this is when Fahrenheit and Celsius/ Centigrade are equal)Then you solve for either F or C, by substituting for either F or C into the equation above (1. if you are solving for F, or 2. if you are solving for C) lets use number 1 and solve for FIt now looks like this:9/5C+32 = 5/9((9/5C+32)-32) (I just put in (9/5C + 32), where F used to be.To solve it we just use some simple rules of equations to try to get C on its ownFirstly divide both sides by 5/9) and it look like this:9(9/5C+32)/5 = ((9/5C+32)-32)Then simplify right hand side by removing the brackets like this:9(9/5C+32)/5 = 9/5C [of course 32-32=0]Next simplify the left hand side by opening brackets (it is done by multiplying everything inside the brackets by 9):(81/5C+288)/5 = 9/5CTo get rid of 5 on bottom of left hand side, you muliply both sides by 5 and get:(81/5C+288) = 45/5CNext remove the brackets arent needed (nothing to do outside the brackets):81/5C+288 = 45/5CNext move Cs together and numbers to other side (by taking 288 from both sides and taking 45/5C from both sides), and it looks like this:81/5C-45/5C =-288Now solve the left hand side (easy as they are both over 5C), so its just 81-45:36/5C=-288Next multiply both sides by 5 (gets rid of the 5 on the bottom of left hand side) and you get:36C=-1440Now we divide both sides by 36 (makes C= to 1), and we get:C=-1440/36Now whack that into a calculator and Hey Presto:C=-40(it also work if you substitute for C)So the temperature at which Celsius = Fahrenheit is -40 degrees(I hope this helped)Use this equation to convert degrees Celsius/Centigrade (ºC) to degrees Fahrenheit (ºF): [°F] = [°C] × 1.8 + 32
If 8b plus 11-3b equals 2b plus 2 what is b?
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
