Answer:
<u>250</u>
Step-by-step explanation:
You can take the explicit formula and simply substitute the n value with 64:
-2 + 4 * (64 - 1)
-2 + 4 * (63)
-2 + 252
<u>250</u>
Answer:
-3/2
Step-by-step explanation:
In the picture attached, the complete question is shown.
The expression is:
You can rewrite the first term, expressing the division as a multiplication, that is, inverting the fraction in the denominator, as follows:
The addition of a negative fraction is simply the subtraction by that fraction:
Which can be simplified dividing by two both numerator and denominator:
Answer:
Answer is 5
Step-by-step explanation:
I don't what the problem is ;-; not sure
5x3-x=10
The angles with measures (5x + 4y)º and 74º are congruent because they form a pair of alternate interior angles between the parallel horizontal bars, so
5x + 4y = 74
The other two labeled angles are also congruent because they are corresponding interior angles that occur between the parallel vertical bars, so
20x + 4y = 164
Then
(20x + 4y) - (5x + 4y) = 164 - 74
(20x - 5x) + (4y - 4y) = 90
15x = 90
x = 6
which means
5*6 + 4y = 74
4y = 44
y = 11
