Step-by-step explanation:

The common ratio is a constant found in geometric sequences, denoted r in the equations for geometric sequences, when any term is divided by the term preceding it. In this case the common ratio is: 147/21=21/3=7=r So 7 is the common ratio.

3) When Jackie took her children to the movie theater, she bought one box of candy and three small drinks for
Nezavi [6.7K]

Answer:

c + 3d = 14.75

2c + 5d = 26

A box of candy is $4.25 and a drink is $3.50

Step-by-step explanation:

Let c represent the cost of a box of candy and let d represent the cost of a drink

c + 3d = 14.75

2c + 5d = 26

Solve by elimination by multiplying the top equation by -2

-2c - 6d = -29.5

2c + 5d = 26

Add them together

-d = -3.5

d = 3.5

Plug in 3.5 as d into one of the equations to solve for c

c + 3d = 14.75

c + 3(3.5) = 14.75

c + 10.5 = 14.75

c = 4.25

So, a box of candy is $4.25 and a drink is $3.50

What is the solution to the system of equations below?
Free_Kalibri [48]

Answer: Infinite solutions.

Step-by-step explanation:

y=-2x-6\\2y=-4x-12

Plug the value of y into the second equation.

\\ 2(-2x-6)=-4x-12\\-4x-12=-4x-12

Add 12 on both sides.

-4x-12+12=-4x-12+12\\-4x=-4x

Add 4x on both sides.

-4x+4x=-4x+4x

0=0
