Answer:The Correct answer is C) the summation from n equals one to 6 of quantity negative 7 minus 3 times n

Step-by-step explanation:

The given Arithmetic sequence: −10, −13, −16, …

Theory : For arithmetic sequence : a, a+d,a+2d......a+(n-1)d

Formula for summation is given as Sn =

Where, a= First term of sequence = (-10) and d= difference of any two consecutive terms = (a+d)-(a) = (-13)-(-10)= (-3)

Putting values in Summation formula

Sn =

Thus, Correct answer is C) the summation from n equals one to 6 of quantity negative 7 minus 3 times n

A certain office supply store stocks 2 sizes of self-stick notepads, each in 4 colors: blue, green, yellow, or pink. The store p

liq [111]

Answer: (C) 16

Step-by-step explanation:

Given : Number of sizes of self-stick notepads= 2

Number of colors = 4

Type 1 : The store packs the notepads in packages that contain 3 notepads of the same size.

i.e. By Fundamental principle of counting , we have

Number of different packages possible = Number of colors x No. of sizes

= $4\times2=8$

Type 2: Notepads of the same size and of 3 different colors.

Choices for 3 different colors out of 4 : $^4C_3=\dfrac{4!}{3!(4-3)!}=4$

Again by fundamental principle :

Number of different packages possible = No. of choices for choosing 3 different colors x No. of sizes

= $4\times2=8$

From Type 1 and Type 2 , the total number of different packages of the types described above are possible =8+8= 16

Hence, the correct answer is option (c) 16.

Answer:

(6x+3)=120

6x=120-3

6x=117

x=117/6

x=19.5

(7x-19)=120

7x=120+19

7x=139

x=139/7

x=19.85

Who can help me on my math I’m failing can y’all please help me on some questions.

tensa zangetsu [6.8K]

Answer:

1 plain pizza costs $10.50 and 1 pepperoni pizza costs $12.50

Step-by-step explanation:

Jack: 3x+2y= 58.5

Jill: 2x+4y=67

a) Multiply both equations so that one of the coefficients (number before the letter) are equal:

6x+4y=117

6x+12y=201

b) We can now easily subtract them to get:

(subtracted 6x) 4y=117 12y=201 (12y-4y and 201-117 next) 8y=84

c) Now we can divide 84 by 8 to get y=10.5, so now we can substitute it into any of the equations:

2x+(4*10.5)=67 --> 2x+42=67 -(subtract 42 from both sides)-> 2x=25 -(divide both side by 2)-> x=12.5.

d) To check if it works: 2(12.5)+4(10.5)=67 25+42=67 so it's correct.
