This graph is a "v" shape with the vertex at (-2,1) and points (0,3) and (-5,4)
This graph is in quadrant 2 and 1
Answer:
zinc = 152 grams
Step-by-step explanation:
Ratio of zinc to copper = 4 : 15
Copper = 570 grams
zinc = x grams
Find x
Ratio of zinc to copper = x : 570
Equate both ratios
4 : 15 = x : 570
4/15 = x/570
Cross product
4 * 570 = 15 * x
2,280 = 15x
x = 2,280/15
= 152
x = 152 grams
zinc = 152 grams
If 21 is the final answer to the equation then x would be 9
235\10=23.5
235:total weight
10:fish caught
23.5: weight per fish caught
you just had to change the amount of fish caught.
