If you are solving for X, the answer will be 25. To solve this, isolate the variable by dividing each side by factors that don’t contain the same variable
Hope this helps :)

Hey there!

5x - 50 + 2x + 80 - x = 180

COMBINE the LIKE TERMS

= 6x + 30 = 180

SUBTRACT 30 to BOTH SIDES

6x + 30 - 30 = 180 - 30

CANCEL out: -30 - 30 because that gives you 0

KEEP: 180 - 30 because it helps solve for the x-value

6x = 180 - 30

180 - 30 = 150

NEW EQUATION: 6x = 150

DIVIDE 6 to BOTH SIDES

6x/6 P 150/6

CANCEL out: 150/6 because that gives you the result of the x-value

x = 150/6

SIMPLIFY IT!

x = 25

Therefore, your answer is: x = 25

Good luck on your assignment and enjoy your day!

Consider all of the four-digit numbers that can be formed using the digits 1, 2, 3, and 4 when no digit is used twice. What is t

Hoochie [10]

Answer:

Option B

Step-by-step explanation:

Given: all the four-digit numbers are formed using the digits 1, 2, 3, and 4 such that no digit is used twice

To find: probability that number chosen lies between 2000 and 3000

Solution:

Probability refers to chances of occurring of some event.

Total number of numbers formed using digits 1, 2, 3, and 4 = $4\times 3\times 2\times 1=24$

Numbers between 2000 and 3000 start with 2. So, first digit is fixed as 2. For remaining three digits, possibilities are 4, 3, 1

So, total number of numbers lie between 2000 and 3000 = $3\times 2\times 1=6$

Probability that number chosen lies between 2000 and 3000 = total number of numbers lie between 2000 and 3000/Total number of numbers formed using digits 1, 2, 3, and 4 = 6/24 = 1/4

In percentage form, Probability that number chosen lies between 2000 and 3000 = $\frac{1}{4}(100)=25\%$

Answer:

$0.000\,000\,067\,12$

Step-by-step explanation:

The exponent of -8 tells you the most significant digit (6) goes in the 8th position to the right of the decimal point.

With some spaces to help in counting decimal places, the number is written ...

$0.000\,000\,067\,12$

HELP PLEASE I WILL MARK BRAINLIEST

Anika [276]

(x,y) to (x,-y). As the triangle is reflected across the x axis, the x value stays the same. Being reflected, the y value is reversed (from negative to positive because the shape is going from below to above)
Hope that made sense

Solve. <br> {2x+7y=2}<br> {x+y=-1}

MaRussiya [10]

So you need to do substitution. First solve the easier equation for 1 variable.
x+y=-1 now subtract x to get y=-x-1. Then plug this into the top equation to get 2x+7(-x-1)=2. Next distribute to get 2x+-7x-7=2. Now combine like terms to get -5x=9 so x=-5/9. Now you have to plug this back into the original equation to get y. 2(-5/9)+7y=2, so -10/9 +7y=2. No move terms around to get 7y=28/9 then divide by 7 to get y= 4/9
