The correct answer is C
Sigma Notation is when we take all of the whole numbers between the starting point (which can be found as the number under the sigma sign) and the end number (which can be found above the sigma sign). Therefore, we will add together all of the values of 3k + 2 for when k is equal to all of the numbers between 2 and 7. So, let's evaluate each one first.
When k = 2
3(2) + 2 = 8
When k = 3
3(3) + 2 = 11
When k = 4
3(4) + 2 = 14
When k = 5
3(5) + 2 = 17
When k = 6
3(6) + 2 = 20
When k = 7
3(7) + 2 = 23
So we know we have the following.
8 + 11 + 14 + 17 + 20 + 23
Now for the number after the comma, we are just looking for the answer of them all added together. So the final answer should be
8 + 11 + 14 + 17 + 20 + 23, 93

Answer:
She can make 4 Red Cards and 6 Pink Cards
Step-by-step explanation:
<u>You need to find a common denominator</u>
So if you have 1/2 a yard of red ribbon and you need 1/8 yards of ribbon to make a card - You would do 1/2 times 4 (1x4=4 || 4x2=) = 4/8
And the same for the Red Ribbon
3/4 - (3x2=6 || 4x2=8) = 6/8
Answer:
a = -15
Step-by-step explanation:
a/-3 -6 = -1
add 6 to both sides
a/-3 = 5
now multiply -3 to both sides
a= -15
