Answer:
-291
Step-by-step explanation:
The common difference is -5
So the 60th term of the arithmetic sequence is
4+(60-1)×-5
=4+59×-5
=4+-295
=-291
Answer:
t = 3
Step-by-step explanation:
Given
- 3 (t - 2) + 7t = 9t - 9 ← distribute left side and simplify
- 3t + 6 + 7t = 9t - 9
4t + 6 = 9t - 9 ( subtract 9t from both sides )
- 5t + 6 = - 9 ( subtract 6 from both sides )
- 5t = - 15 ( divide both sides by - 5 )
t = 3
Answer:
Step-by-step explanation:
Is it possible for Bruce and Felicia to have used the same number of tiles? Use complete sentences to explain your reasoning.
No
5x + 2 ≠ 5x + 5
because
2 ≠ 5
If they each used the same number of tiles, how many tiles were in each box?
6x + 2 = 5x + 17
6x - 5x + 2 - 2 = 5x - 5x + 17 - 2
x = 15 tiles
The first thing we must do for this case is to find the relationship between the variables.
We have then:
From here, we clear the value of "Y":
On the other hand we have:
From here, we clear the value of "x":
Then, replacing values we have:
On the other hand:
Finally, the perimeter is given by:
Substituting values we have:
Answer:
the perimeter of ABCD is:
44 units
