I'm not 100% sure but this is how i worked it out
1/3 x 114/1 = 38
114 - 38 = 76 hydrogen
Hope this helps
To find the equation of a line using two coordinate points, use the slope intercept formula, (y2-y1)/(x2-x1). Using this formula, plug in your values from the two coordinates (-5, -5) and (1, -3). This would look like this:
(-3-(-5))/(1-(-5))
When simplified, you should get 2/6 or 1/3 as your slope or m value. Now that you have your slope, now use your slope intercept equation y=mx+b and plug in your known values. Since you know the m value is 1/3 and you can use one of your set of points to plug into the x and y values, you can plug in these values and solve for b (the coordinate you use doesn't matter but I'm just using the (1,-3)). This would look like this:
-3=1/3(1)+b
When you simplify, you should get -3=1/3+b and when you subtract both sides by 1/3, you should get b=-10/3.
Now that you have your m and b values, you can conclude that your equation for the line would be y=1/3x-10/3
Answer:
x = 1
y = -24
Step-by-step explanation:
8x + y = -16
-3x + y = -5
Subtract equation one from equation two
8x - -3x + y - y = -16 - - 5
8x + 3x = -16 + 5
11x = 11
Divide both sides by 11
11x/11 = 11/11
x = 1
Now substitute 1 for x in either of the equations to get y.
Using equation one, we have
8x + y = -16
8 x 1 + y = -16
8 + y = -16
Subtract 8 from both sides
8 - 8 + y = -16 - 8
y = -24
x = 1
y = -24
