7(3x + 2) = 18 - (x + 48)

Distribute on both sides. On the left side, multiply each term in parentheses by 7. On the right side, a negative sign to the left of parentheses is as if a -1 is there, and you must multiply everything inside the parentheses by -1.

7(3x + 2) = 18 -1(x + 48)

21x + 14 = 18 - x - 48

21x + 14 = -x - 30

22x = -44

x = (-44)/22

x = -2

Answer: x = -2

If x is a positive integer and y is a negative integer than x + y is a rational number.

romanna [79]

Answer:

Yes

Step-by-step explanation:

An integer is a whole number so if x is positive and y is negative then the equation would just be x plus negative y. But x+-y is an odd equation so the simplified version is x-y so it is a rational number, since a rational number is a number that can be rewritten as a simple fraction.

What is the solution to the equation 2(x - 3) = 2x + 5

Genrish500 [490]

Hello there!

2(x - 3) = 2x + 5

Let's start by using the distributive property for the left side.

(2)(x) + (2)(-3) = 2x + 5

2x - 6 = 2x + 5

Then we need to add 6 to both sides

2x - 6 + 6 = 2x + 5 + 6

2x = 2x + 11

We need to transfer 2x on the left side, we gonna do that by subtracting 2x from both sides

2x - 2x = 2x + 11 - 2x

0 = 11

Thus,

There are no solutions.

I hope this helps!

Good luck with your career!

fatima claims that the distribution of u is uniform with a median of 0.4 field goal percentage. is fatima’s claim supported by t

Amanda [17]

Fatima's claim is not supported by the table because, the distribution is skewed right, with a median of 0.4 field goal advantage.

From the table, the median position is calculated as:

$\mathbf{Median = \frac{1}{5} th}$

$\mathbf{Median = 0.2\ nd }$

The 0.2nd data falls in the 0.4 field goal category.

So, the median element is:

$\mathbf{Median = 0.4}$

However, the distribution of the table are concentrated on the left.

This means that, the distribution is not uniform, instead it is skewed right.

A uniform distribution has a skewness of 0.

Hence, Fatima's claim is not supported by the table

Katena32 [7]

By this equation y = 1,716 - 112x he find that how much money he still owes after each month of the plan.

According to the statement

Jonathan bought a new computer for $1,716

He will pay $143 a month for 12 months.

Total amount he will for 12 months is 143(`12)

Now,

y = the money he still owes

x = the number of months (from x = 0 to x = 12)

y = 1,716 - 112x

So, By this equation y = 1,716 - 112x he find that how much money he still owes after each month of the plan.
