Answer:
first you have to divide 697 / 17 because 17 is the copper
and you want to know how much pairs it gives you
and the answer is 41 so you're forty-one pairs now u times 41 with 3 to find the grams of zinc in the certain chemical. and 41 * 3 = 123
so you have 123 grams of zinc in the certain chemical
Step-by-step explanation:
Answer:
7.5x6.5=48.75
Step-by-step explanation:
The two points we are given will tell us the slope of the line, and the first point even tells us the y intercept.
slope = (y2 - y1) / (x2 - x1) = (1 - 4) / (1 - 0) = -3/1 = -3
Since the function goes through (0,4), our y intercept is 4.
Now we can fill in our function:
<span>y = _ x + _
</span><span>y = -3x + 4</span>
