Write in 0 and 0 at the top: this indicates that if there are zero pennies, the height of the tower is 0. This is the point (0,0). Another point is (4, 28): a tower of 28 pennies is 4 cm tall.
Find the slope of the line connecting (0,0) and (4,28).
4cm - 0 cm
m = ----------------- = (1/7) (cm/penny)
28 - 0
The equation we need, relating # of pennies to height of tower, is
t = (1/7) (cm/penny)x, where x is the # of pennies.
Thus, if x = 1, then t=1/7 cm
And, if x =15, then t = 15/7 cm
And so on.
Answer:
-20 7/20, 7/28, 20, 20.75
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given: 10 less than
is 35.
To find: The equation of the given situation.
Solution: We need to write an equation for 10 less than
is 35.
Here, we will break down the sentence to form the equation.
10 less than
means
.
Then, it says 10 less than
is 35 which means it is equal to 35.
So, the sentence 10 less than
is 35 can be written as 10 less than
is equal to 35.
Now, 10 less than
is equal to 35 can be shown as
.
Therefore, the required equation is
.
<span>This must be your answer:
Expanded: 1/5 x 10x + 1/5 x -25 </span>
It would be 28-10=x because your ending up with 28 after earning 10 you would get that. Hope this works!
