Jeannie got a new pair of eye glasses. She was able to pay $15 at the
time she received her glasses. She will pay $12 each month on the
balance. The original cost of the glasses was $87.
b. How many months will it take Jeannie to pay for her glasses?

Answers

Answer 1

Answer:

6 months

Step-by-step explanation:

12x = 87

12x ÷ 12 = x

87 - 15 = 72

72 ÷ 12 = 6

x = 6 months

CHECK:

12 x 6 = 72 + 15 = 87

87 = 87

Answer 2

Answer:

6 months

Step-by-step explanation:

The equation would be: 15 + 12m = 87

Olivia has a points card for a movie theater. She receives 25 rewards points just for signing up. She earns 7.5 points for each visit to the movie theater. She needs 130 points for a free movie ticket. How many visits must Olivia make to earn a free movie ticket?

Answers

Answer:

14

Step-by-step explanation:

7.5x + 25 = 130

         -25    -25

7.5x = 105  

[tex]\frac{7.5x}{7.5}=\frac{105}{7.5}[/tex]

x = 14

Answer:

(-4,-4)

Step-by-step explanation:

6x - 7y = 4

6(-4) - 7(-4) = 4

-24 + 28 = 4

4 = 4 This is correct to the first equation.

Now let us try the second equation.

-5x + 3y = 8

-5(-4) + 3(-4) = 8

20 - 12 = 8

8 = 8 This is also correct to the second equation.

Select the solution(s) of log2x=1−log(x+4).

Answers

Step-by-step explanation:

log2x = 1 - log(x+4)

log2x = log10 - log(x+4)

log2x = log[10/(x+4)]

2x = 10/(x+4)

2x(x+4) = 10

2x² + 8x - 10 = 0

÷2 both sides of equation

x² + 4x - 5 = 0

(x+5)(x-1) = 0

x = -5, 1

x isn't be -5 because logA, A need to be > 0

So, x value is 1

A plant is already 54 centimeters tall, and it will grow one centimeter every month. The plant's height, H (in centimeters), after M months is given by the following.
What is the plant's height after 13 months?

Answers

Answer:

67 cm

Step-by-step explanation:

We are given the initial height of the plant let's call it H.

H = 54 cm. This is the original height of the plant at M(months) = 0.

We are given that it grows at 1 cm/month. This is the rate of growth.

Rate = 1

Time (M) is given in Months.

So when M = 0, H = 54

Let's say M = 1, That is one month has passed. In this time the plant's height would have increased by 1 cm. So our plant's height would be H = 54+1 = 55 cm.

When Two months have passed our plant's height would be H = 54 + 2 = 56 cm , since every month our plant gains 1 cm in Height, we can make a fuction for this.

H = 1M + 54.

Now we just plug in 13 for M, to get 13 months.

H = 13 + 54

H = 67 cm

So our plant would be 67 cm in height after 13 months.
