First term: a1 = 151
common difference: d = -14 (we decrease by 14 each time, eg, 151-14 = 137)
nth term of this arithmetic sequence is...
an = a1+d(n-1)
an = 151+(-14)(n-1)
an = 151-14n+14
an = -14n+165
This will be used in the formula below
Sn = n*(a1+an)/2
<span>Sn = n*(151+(-14n+165))/2
</span><span>S26 = 26*(151+(-14*26+165))/2 ... replace every n with 26
</span>S26 = -624
The final answer here is choice C) -624

Answer:
2x + 3y = $54
Step-by-step explanation:
Standard Form ~ Ax + By = C
A and B in this case are just going to be numbers, they are just for substitution purposes.
Since x is fruit flavored candy and y is Chocolate, we can substituce the Fruit for A and Chocolate for B.
Now, we have 2x + 3y = C
The C is going to be the total cost. Therefore we have ~
2x + 3y = $54
Have a great day,

Answer:
The answer is (0.5, 0)
Step-by-step explanation:
You're asking
(10⁶) times (10^p) = 10¹⁸ .
When you multiply two numbers that have the same base
but different exponents, you just add the exponents.
So 6 + p = 18
Subtract 6 from each side: p = 12 .
10⁶ x 10¹² = 10¹⁸ .
P=6.50*10-18.00
hope this helped!❤️
