Answer:
30 = 9x + 7
Step-by-step explanation:
The total weight of the bundle = 30 pounds
The weight of the bricks = x pounds
But he carried 9 bricks = 9x pounds
He also carried additional 7 pounds of concrete block.
An equation to show the total weight he carried is
30 pounds = (9x + 7) pounds
Since 9x represents the total weight of the bricks he carried
7 represents the weight of the concrete block
And 30 pounds represents the total weight of everything he carried.
Here are your answer's:
Number three would goes with "no relationship"...…
Number one would goes with "<span>causation</span>".....
Number two goes with "correlation"...…
<u>Correlation is the relationship between more than two things which is why it would go with number to because literacy rates go with the increase of doctors. Causation is like a cause and effect so in this case the cause would be a increase of the population and the effect would be more people who don't have jobs. No relationship would go with number three since how snowfall doesn't have anything to do with personal income. (which is how much a person makes) </u>
Hope this helps!
