1. -3x+32= -x-12 2. 8x+16=x+9 3. 3x + 2 = 2x -55 I need all the steps to all three of those questions

Answers

Answer:

Step-by-step explanation:

1. - 3x + 32 = - x - 12

-3x + x = - 12 - 32

-2x = - 44

x = 44/2 = 22

2. 8x + 16 = x + 9

8x - x = 9 - 16

7x = - 7

x = - 7/7

= - 1

3. 3x + 2 = 2x - 55

3x - 2x = - 55 - 2

x = - 57

What is median?

In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

here, we have,

The center of a data set is mostly considered as the median or the mean

Here mean is 6 (given). And median is also 6.

As 6 is exactly at the middle of the data set. (When arranged in ascending order)

Now, one of the way of calculating the spread is calculating the range, here it's given that the range is 9.

Therefore, 6 feet describes the center, and 9 feet describes the spread is correct.

Ellen bought new fish for her home aquarium. She bought 4 Turquoise Guppies and 3 Sunburst Tetra GLO Fish and spent a total of $41.73. Danielle bought 3 Turquoise Guppies and 5 Sunburst Tetra GLO Fish for a total of $56.02. How much was one Turquoise Guppy.

Answers

Answer: Ellen: 4t + 3s = 41.73

Danielle: 3t + 5s = 56.02

t = $3.69 each

Step-by-step explanation:

with 4t + 3s = 41.73 and 3t + 5s = 56.02

you need yo eliminate s to get t so multiply 3t + 5s = 56.02 by -3/5 to get

-9/5t - 3s = -33.612 then add 4t + 3t = 41.73 to get

11/5t = 8.118 then divide 8.118 by 11/5 to get

t = 3.69

-2x-10=2x+14 i need all the steps

Answers

Answer:

x = -6

Step-by-step explanation:

1. always group the unknowns in this case, we 'bring' over the -2x to the right side so it becomes

-10 = 2x + 2x +14

2. Move 14 to the left side,

-10 - 14 = 2x + 2x

3. Carry out addition on both sides,

-24 = 4x

4. Simplify: since 24 is divisible by 4, so we divide 4 on both sides

-6 = x

Answer: x=-6.

Step-by-step explanation:

First, we need to choose an x side, and a non-x side. Let's choose the right side as the x side since it's coefficient of x is greater than that of the left side. So, we add 2x on each side to get rid of the x on the left side. Now, we have -10=4x+14. Next, we should subtract 14 from each side to get rid of the non-x terms on the right side. Now, we are left with -24=4x. Finally, we can divide by four on each side to get x=-6.
