Convert all to either meters, centimeters or millimeters.
2.0 m = 20 x 101 cm (200 without significant digits)
50.0 cm = 50.0 cm
200.0 mm = 2.00 cm
Multiply
200 cm x 50 cm x 2 cm = 8000 cm = 80 m = 8 dam (decameters)
How do you solve x plus 3 equals 5?
X+3=5 Is the same as 2+3=5. One way to look at it is to subtract the number from te answer. So, 3-5 equals 2. 2=X.
What is the slope of 4x equals -3y plus 8?
4x = -3y+8
3y = -4x+8
y = -4/3x+8/3
So the slope is -4/3 or -1 and a 1/3
How do you solve the proportion x5 equals 1610?
Assuming that the question is find x in x5=1610; the answer is 4.378901
What is x if 3X plus 13 equals 61-3X?
3x + 13 = 61 - 3x : add 3x to both sides
6x + 13 = 61 : deduct 13 from both sides
6x = 48 : divide both sides by 6
x = 8
Prove that tan(x)sin(x) = sec(x)-cos(x)
tan(x)sin(x) = [sin(x) / cos (x)] sin(x)
= sin2(x) / cos(x)
= [1-cos2(x)] / cos(x)
= 1/cos(x) - cos2(x)/ cos(x)
= sec(x)-cos(x)
Q.E.D
What is the slope of the graph of 7x equals 3y minus 8?
7/3 im pretty sure
Another Answer:-
If: 7x = 3y-8
Then: -3y = -7x-8
And so: y = 7/3x+8/3
Therefore: the slope is 7/3 and the y intercept is 8/3
Can you help with this equation? Thanks.
Solve for x and y and z for the following.
x plus y plus z equals 9
x plus 2y plus 3z equals 23
x plus 5y plus -3z equals -7
How do you factor 5x2 plus 5x - 5 equals 0?
you would first do 10+5x-5=0, then 5x+5=0 and is factored by 5(x+1)=0. or if you want to know what x equals with, x=-1
Is y equals 2x plus 1 a function?
No. That is an equation. A fraction can be plugged into it for x or y. An example of a fraction is 1/2
How many solutions 4x2 plus 8x plus 3 equals 0?
Start with the equation 4x2 + 8x + 3 = 0.
Invoke the quadratic equation:
x = [-b ± √(b2 - 4ac)]/2a, where a = 4, b = 8, and c = 3.
Plug in the values for a, b, and c and solve:
x = [-8 ± √(82 - 4*4*3)]/2*4,
x = [-8 ± √(64 - 48)]/8,
x = -1 ± √(16)/8,
x = -1 ± 1/2,
x = {-1/2, -3/2}.
