An equation is shown below:3(4x − 2) = 1

Which of the following correctly shows the first two steps to solve this equation?
Step 1: 12x − 2 = 1; Step 2: 12x = 3

Step 1: 12x − 6 = 1; Step 2: 12x = 7

Step 1: 7x + 1 = 1; Step 2: 7x = 0

Step 1: 7x − 5 = 1; Step 2: 7x = 6

Answers

Answer 1
Answer:

Answer:

The correct option is 2.

Step-by-step explanation:

The given equation is

3(4x-2)=1

Step 1: use distributive property.

3(4x)+3(-2)=1

12x-6=1

Step 2: Add 6 on both the sides.

12x-6+6=1+6

12x=7

Therefore the correct option is 2.
Answer 2
Answer:

Answer:

Ya'll trippin', the person above is correct, it's the second option;

Step 1: 12x - 6 = 1; Step 2: 12x = 7

Step-by-step explanation:

How do I know?

3(4x - 2) = 1

(do distributive property)

so 3 times 4x and 3 times -2

12x - 6 = 1

(add +6 to 1; you do + 6 because you do the opposite of the og sign)

12x = 7

SO, the answer is clearly the second option.

300,000 to nearest 100,000?

Answers

Answer:

The answer is 3

Step-by-step explanation:

100,000 times 3 equal 300,000.

hope this helps you :)

Final answer:

When rounding 300,000 to the nearest 100,000, the result is 300,000 because it’s already a multiple of 100,000.

Explanation:

The question is asking to round the number 300,000 to the nearest 100,000. When rounding numbers, you look at the digit immediately to the right of the digit place you're rounding to. If this digit is 5 or greater, you round up; if it's less than 5, you keep the original number. In the case of 300,000, there are no digits to the right of the 100,000's place because it's already a multiple of 100,000. Therefore, 300,000 rounded to the nearest 100,000 is 300,000.

Given:

The price of a share of stock in JZMobile was $74 two weeks ago.

Seven weeks ago, the price was $59 a share.

To find:

The linear equation to find the price p of a share of JZMobile w weeks from now.

Solution:

Let, p be the price of a share of JZMobile w weeks from now.

The price of a share of stock in JZMobile was $74 two weeks ago. It means, the graph of linear equation passes through (2,74).

Seven weeks ago, the price was $59 a share. It means, the graph of linear equation passes through (7,59).

The graph of linear equation passes through two points (2,74) and (7,59). So, the linear equation is

y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

y-74=(59-74)/(7-2)(x-2)

y-74=(-15)/(5)(x-2)

y-74=-3(x-2)

y-74=-3x+6

Adding 74 on both sides, we get

y=-3x+6+74

y=-3x+80

y=80-3x

Therefore, the correct option is C.

Please help...The radius of the planet is 4100 miles. Find the distance d to the horizon that a person can see on a clear day from a height of 1298 feet above the planet. (hint: use the conversion 1 mile = 5280 ft) Round your answer to the nearest 10th, and don't forget to convert feet to miles.

Answers

First, we are going to convert 1298 feet to miles. Since we know that 1 mile = 5280 ft, we are going to multiply 1298 ft by (1mi)/(5280ft) to do that:
1298ft*(1mi)/(5280ft)= (59)/(240) mi

Next, we are going to set up a right triangle using the radius of the Earth and the distance above the planet.
The hypotenuse of our triangle will be the radius of the Earth + the distance above the planet. One of the legs of our triangle will be the radius of the Earth, and the other leg, d, will be the distance that a person will see on a clear day.
Using the Pythagorean theorem:
d^2= ((984059)/(240) )^2-4100^2
d= \sqrt{((984059)/(240) )^2-4100^2}
d=44.9 miles

We can conclude that the distance, d, to the horizon that a person can see on a clear day from a height of 1298 feet above the planet is 44.9 miles.

Solve for x 4x-4<8 and 9x+5>23

Answers

Answer:idk

Step-by-step explanation:

Answer:

9x > 18

Step-by-step explanation:

Answer:

(i) x<3

(ii) x > 2

Step-by-step explanation:

4x - 4 < 8

Add 4 to both sides of the equation , that is

4x - 4 + 4 < 8 + 4

4x < 12

divide through by 4

x<3

Also

9x + 5 > 23

subtract 5 from both sides , that is

9x > 18

x > 2
