Answer:

x=-2

Step-by-step explanation:

[tex]125^{2x}=5^{4x-4}\\(5^3)^{2x}=5^{4x-4}\\5^{6x}=5^{4x-4}\\6x=4x-4\\6x-4x=-4\\2x=-4\\x=\frac{-4}{2}=-2[/tex]

Answer:

4 times, he bought dinner 4 times

Step-by-step explanation:

if kevin get paid for 3 hours, then you would multiply $14 by 3. you would end up with $42, then the weekly allowance is $21. then by adding $21 to the $42 we have you would get $63. then a bus ride costs $2.50 and since he rode it 6 times you would multiply $2.50 by 6, which would equal $15. Then subtracting $15 from the $63, you would end up with $48, and then by dividing the total amount for the dinner each time bought, so $12/$48 would equal to 4 times.

Answer:

20

General Formulas and Concepts:

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

m³ - (n + 6 · m) + 4n

m = 2, n = 8

Step 2: Evaluate

Answer:

The answer would be 3b + 20 = t

Step-by-step explanation:

I think the question is referring to the total cost per month to be a member.

Since it costs 20$ monthly no matter what, that price will always stay the same per month.

However, it also costs $3 per book purchased. This price may not always stay the same, because you could buy a different number of books each month, and the price would be different. The cost for books depends on the number of books you buy, which is not stated in the question.

That is why you replace the number of books with a variable, in this case b.

So the equation would be 3b + 20 = t , with 3 being the cost per book, b being the number of books, 20 being the monthly cost, and t being the total amount per month.  

Answer:

(-1, 1)

Step-by-step explanation:

Multiply f(x) or y value by -2, so (-1, 2) -> (-1, -4)

Add 5 to the f(x) or y value since it is a vertical translation, so (-1, -4) -> (-1, 1)

Answer:

first determine the gradient because the equation of a straight line is y=mx+c

therefore gradient=change in y/change in x

=y2-y1/x2-x1

=4-3/-3-(-3)

=1/0

there fore gradient of the line is undefined

y=x+c

4=-3+c

4+3=c

7=c

therefore y=x+7

Answer:

y = x + 5

Step-by-step explanation:

Using the information provided we can create the following equation. Since every seed packet can grow 1 single flower we would need to multiply 1 by the number of seed packets (x), which simplified would be just x . Next we are told that Steve already has 5 flowers in his possession meaning we need to add this to the new flowers that he is growing to get the total number of flowers.

y = x + 5

Divide the amount of saving by the percent of saving:

160/0.20 = 800

The original price was $800

Answer:

Initial deposit P = 4,801 (Approx.)

Step-by-step explanation:

Given:

Amount after 4 year = 5,300

Number of year = 4 year

Rate = 2.5% = 0.025

Find:

Initial deposit

Computation:

A = P[1+r]ⁿ

5,300 = P[1+0.025]⁴

5,300 = P[1.025]⁴

5,300 = P[1.1038]

Initial deposit P = 4,801 (Approx.)

Answer:

$00.20 per min

Step-by-step explanation:

Technically $12.00 per hour is $12.00 per 60 min. So now take that and divide $12.00 by 60 and you get 20 cents per min.

Answer:

0.2$ per min

Answer:

1. 5 + (-2), 5 - 2, and 3

2. 7 + 2

Step-by-step explanation:

1. If we look at the model, there are 5 positive circles and 2 negative circles. This means that we can write it in :-

2. It asked for an equivalent to 7 - (-2). Remember that negative and negative would be positive. So, it would become 7 + 2.

I would appreciate if you give me the brainlist or not. Hope this helps and stay safe, happy, and healthy, thank you :) !!

Answer:

The height of the sunflower plant is 1.57 meters.

Step-by-step explanation:

Initially, the height of the sunflower plant was of 1.25 m.

Then, it grew by 0.32 m, that is, we have to add 0.32 m to the height.

Sum of decimals:

Dot below dot, add normally. So

 1.25

+0.32

---------

1.57

So

The height of the sunflower plant is 1.57 meters.

Answer:

Step-by-step explanation:

The mean of the data is 31 hours and the median of the data 27.2 hours.

24 of the families in the sample turned on the television for less than 16 hours for the week.

The 7th percentile = 16 hours

Step 1:

The median is a value that divides the whole data into two equal parts. It implies that the median represents the 50th percentile of the data.

Given that the median is 27.2 hours, thus the 54th percentile should be greater than 27.2 hours.

Thus, the given statement is false.

Step 2:

Let assume that N is the total number of families

24 of the families in the sample turned on the television for less than 16 hours for the week.

The 7th percentile = 16 hours

It means that 7% of N = 24

N = 24/0.07

N = 343

Step 3:

From (2), N = 343

Given that median= 27.2 hours.

It means 200 families turned on their television for less than 27.2 hours.

We don't know if this is true for 35 hours. 100 families may use less than 35 hours and 200 may use more than 35 or vice versa. In addition to that, even 50 families might use less than 35 and 350 may use more than 35 hours.

Hence, the statement is false.

Step 4:

The median is the 50th percentile value which is = 27.2 hours

Step 5:

The statement is false

The 25th percentile is the first quarter of the data and if the 7th percentile is 16 hours, then the 25th percentile should be greater than that.

Answer:

C. 108.5 square feet

Step-by-step explanation:

Area of a rectangle: length x width

Area of a triangle: (base x height)/2

First find the rectangle's area:

10ft x 7 ft

70ft^2

Find the right side triangle's area:

(7ft x 5ft)/2

35ft^2/2

17.5ft^2

Now find the left side triangle's area:

There is no base number included, but the other triangle has a base of 7ft. Considering the triangle is attached to a rectangle's side, we can conclude this triangle will have the same base because a rectangle's parallel side will always equal each other

(7ft x 6ft)/2

42ft^2/2

21ft^2

Finally, add all of these areas together

70ft^2 + 17.5ft^2 + 21ft^2

87.5ft^2 + 21ft^2

108.5ft^2
