Answer:
x = 0
Step-by-step explanation:
5(x - 3) + 4(x + 3) = 3(x - 1)
5x - 15 + 4x + 12 = 3x - 3
5x + 4x + 12 - 15 = 3x - 3
9x - 3 = 3x - 3
9x = 3x - 3 + 3
9x = 3x
9x - 3x = 3x - 3x
6x = 0
6x ÷ 6 = 0 ÷ 6
x = 0
Answer:
5( x− 3 ) + 4 ( x +3)
9x − 3 = 3(x− 1 ) Simplify 3 ( x − 1 ) .
9 x − 3 = 3 x − 3
Move all terms containing x to the left side of the equation.
6 x − 3 = −3
Move all terms not containing x
to the right side of the equation.
6 x = 0
Divide each term by 6 and simplify.
x = 0
. A bag contains 7 orange beads, 3 red beads, and 5 white beads. What is the probability of
drawing a white bead?
Answer:
Work shown below!
Step-by-step explanation:
White bead = [tex]\frac{5}{15} =\frac{1}{3}[/tex]
Answer:
a 33.3333333% chance
Step-by-step explanation:
we do 7+3+5= 15 (the denominator)
and so the amount of white beads in total is 5/15
5÷15+100= 33.333333333 and so on percent
Mr. Hon purchases a new car every 4 years. Ms. Jasper purchases a new car every 6 years. They both purchased new cars this year. When will they next both purchase new cars in the same year?
Answer:
12 years
Step-by-step explanation:
Given that Mr. Hon purchases a new car every 4 years. Ms. Jasper purchases a new car every 6 years.
Assuming that they purchase new cars together after n years.
So, n must a multiple of 4 as well as multiple 6, i.e the number n is the lowest multiple (LCM) of 4 and 6.
As LCM od 4 and 6 is 12, so n=12.
Hence, after 12 years they will purchase news cars together.

The number of candies in the box is between 80 and 100. It is possible to divide all the candies among 2, 3 or 5 children. How many candies are in the box?
Answer:
90
Step-by-step explanation:
The number of candies can be divided among 2, 3, or 5 children so that is the same as saying: the number of candies must be divisible by 2, 3, and 5. In order for a number to be divisible by 5, it must end in 0 or 5 so we know the number of candies must end in 0 or 5. For a number to be divisible by 2, the number must end in an even number. 5 is not an even number so we know the number of candies must end in 0. If a number is divisible by 3, the digits added are divisible by 3. Go through each number(80, 90, 100) and see which one is divisible by 3. 90 is divisible by 2, 3, and 5.
Proof that 90 is divisible by 2, 3, and 5:
90 ÷ 2 = 45
90 ÷ 3 = 30
90 ÷ 5 = 18
The results are all whole numbers.

What is a furry? If I draw fursonas am I a furry? I am seriously questioning my life rn. Plz help.
Don’t hate on furries plz
Answer:
iam sorry but furries are good lg!!!
Furry can have two definitions. A furry is either an anthrophomorphic animal which has human characteristics or a person that shows interest in furries. If you draw other people's fursona, i don't think that makes you a furry tbh. If you show interest and if you have your own fursona and you're passionate about it, however, then yeah you're pretty much a furry. Being a furry isn't bad honestly, it's just a hobby. I'm a furry myself and i honestly love this fandom. I met a lot of great people!

In order to write the equation of the line passing through the point (-2, 2) that is parallel to the line y = 2x + 3 , the next step is to find the y-intercept of the perpendicular line. What is the y-intercept of the perpendicular line through point (-2, 2)?
Answer:
Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.
Answer:
See below.
Step-by-step explanation:
This question makes no sense.
Here is the question. Pay attention to the words in boldface.

3h -8 > 22
Please and thank you
Answer:
I think it's 11
Step-by-step explanation:
11 times 3 is 33 minus 8 is 25 and 25 is greater than 22
Answer:
h > 10
Step-by-step explanation:
3h-8>22
1. Separate the coefficient and variable.
Separate 3h, we'll save that for later.
2. Use inverse operations and apply it to both sides of the equation.
In this case, it is subtraction, so we will add 8 to both sides of the equation.
3h - 8 > 22
+ 8 + 8
That gives us 3h > 30, because the 8 and 8 cancels out.
3. Use inverse operations. (3h and 30.)
In this case, it is multiplication, so we will divide 3 from both sides of the equation.
3/3 > 30/3
30 divided by 3 is 10, therefore, the answer is h > 10
(Since we did not divide 30 with a negative number, the sign stays the same, and it is not switched.)
What is the value of p? Please provide an explanation, thanks!
Answer:
[tex]p=39.4[/tex]°
Step-by-step explanation:
[tex]4a+4+75+p=180[/tex] (The sum of angles on a triangle is [tex]180[/tex]°)[tex]4a+p=180-4-75[/tex]
[tex]4a+p=101[/tex]
[tex]p+9a+2=180[/tex] (Angles of a straight line sums to [tex]180[/tex]°)
[tex]p + 9a = 178[/tex]
Elimination can be used to find the value of one variable:
[tex]p+9a-(4a+p)=178-101[/tex]
[tex]5a = 77[/tex]
[tex]a=15.4[/tex]
Now, the value of [tex]p[/tex] can be found by using substitution:
[tex]4a+p = 101[/tex]
[tex]4(15.4)+p=101[/tex]
[tex]p = 101-61.6[/tex]
[tex]p = 39.4[/tex]

We're told that the section rises by 1 unit
[tex]1 = 0.28(run)\\[/tex]

Write the equation of a line passing through the given point that is
perpendicular to the given line. 3.x – 8y = 16; (-3, 1)
Answer:
-8x-21=3y or -8/3x-7=y or 8x+y+21=0
Step-by-step explanation:
First find the slope of 3x-8y=16.
3x-16=8y (divide both sides by 8 so that y is isolated)
3/8x-2=y The slope is 3/8. The perpendicular slope is the negative reciprocal of 3/8, which is -8/3
Using the points, the equation of the line can be found.
(-8/3=y-1/x-(-3))3(x-(-3) (3(x-(-3) is the common denominator
This equals -8x-24=3y-3, add three to both sides which equals -8x-21=y.
The other answers are written in slope y-intercept form and general form.
*Note: x-(-3) can be written as x+3
