Rearrange the equation to solve for x 3kx+2kx=10.
Answer:
[tex]kx-2=0[/tex]
Step-by-step explanation:
We are given that an equation
[tex]3kx+2kx=10[/tex]
We have to find the value of x by rearrange the equation
Subtract 10 on both sides then we get
[tex]3kx+2kx-10=0[/tex]
Now, combine like terms
[tex]5kx-10=0[/tex]
Now, taking common factor
[tex]5(kx-2)=0[/tex]
[tex]5\neq 0[/tex]
Therefore,
[tex]kx-2=0[/tex]
This is required equation to solve for x.

at 12pm there are 855 people in the zoo by 5pm 4/5 of the children have left and ³/₄ of the adults have left. There are now 36 more children than adults in the zoo.working out
Answer:
300 Adults 555 Children
Step-by-step explanation:
What we know:
Firstly, at 5pm there were 36 more Children (C) than Adults (A)
So.....C = A + 36
Secondly, at 12pm there were 5 x more Children and 4 x more Adults and the total was 855
So 4A + 5C = 855
——-
Now use ‘C = A + 36’ and get rid of all ‘C’ in the second equation.....
4A + 5C = 855
becomes......
4A + 5 (A + 36) = 855
Multiply the brackets (5 x A) and (5 x 36):
4A + 5A + 180 = 855
Take off 180 from both sides:
4A + 5A = 675
Therefore 9A = 675
Divide by 9:
A = 75
We know C is A + 36
C = 111
At 5 pm - A = 75 and C = 111
Therefore at 12:
There were 5 x C = 555
And 4 x A = 300

(a)
Given
x² + 10x + 16
Consider the factors of the constant term (+ 16) which sum to give the coefficient of the x- term (+ 10)
The factors are + 2 and + 8, since
2 × 8 = 16 and 2 + 8 = 10, thus
x² + 10x + 16 = (x + 2)x + 8)
---------------------------------------------------
(b)
Given
x² + 7x + 12
Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 7)
The factors are + 3 and + 4, since
3 × 4 = 12 and 3 + 4 = 7, thus
x² + 7x + 12 = (x + 3)(x + 4)
------------------------------------------------------
(c)
Given
x² + 13x + 12
Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 13)
The factors are + 1 and + 12, since
1 × 12 = 12 and 1 + 12 = 13, thus
x² + 13x + 12 = (x + 1)(x + 12)

Hope this helps plz mark brainliest!
Answer: B. y = -3x
Step-by-step explanation:
By plugging in the given point into each answer choice for the x and y values for which ever equation is true that is the correct answer.
For the purpose of speeding things up the correct answer is B y = -3x
If we plug in the point give, (1, -3) for (x, y) then we get the equation:
-3 = -3 * 1
This equation when solved: -3 = -3 which is true so this is the correct answer.
Point A is at (-8, 5) and point M is at (-1.5, 1). If M is the midpoint of line segment AB, what are the coordinates of point B?
Answer:
(5,-3)
Step-by-step explanation:
If point A is 6.5 on the x axis away from point M, then point B must be the same distance away. -1.5+6.5=5. If point A is 4 on the y axis away from point M then point B must also be the same distance away. 1-4=-3.
So the answer must be (5,-3)

What is the measure of angle TRV?
O 20°
O 50°
60°
O 130°
Answer:
•130°
Step-by-step explanation:
...........…..
The measure of the angle ∠TRV from the intersecting lines is ∠TRV = 130°
What are the angles formed by 2 intersecting lines?Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.
Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.
When lines intersect, two angle relationships are formed:
Opposite angles are congruent
Adjacent angles are supplementary
Given data ,
Let the two intersecting lines be m and n
Now , the linear pair of angles are supplementary or Adjacent angles are supplementary
And , the measure of ∠TRV + ∠TRS = 180°
On simplifying , we get
(x - 10)° + (2x + 10)° = 180°
x - 10 + 2x + 10 = 180°
3x = 180°
x = 60°
Now , the measure of m∠TRV = ( 2x + 10 )°
m∠TRV = 2( 60 ) + 10
m∠TRV = 130°
Hence , the measure of angle ∠TRV = 130°

Carter is handing out Valentine’s Day cards to his friends. He has 8 Batman cards, 12 Superman cards, and 5 captain America cards in a bag. What is the probability that the first two he chooses are Batman?
Answer:
7/75
Step-by-step explanation:
8 Batman cards, 12 Superman cards, and 5 captain America =25 cards
P( batman) = 8/25
no replacement since he hands them out
7 Batman cards, 12 Superman cards, and 5 captain America =24 cards
P( batman) = 7/24
P(batman, no replacement, batman) = 8/25 * 7/24 = 7/75

The number that is a perfect square remains on the outside and the one that isn't, stays on the inside. For example, you can make the number 2[tex]\sqrt{3}[/tex] only when the number on the outside is a perfect square. The original number was 4, so it reduced down to 2, and the other number stayed in the radical

Answer: C) Outside the circle
Step-by-step explanation: Ok, so we know 0,0 is the center of the circle and 5,8 is on the circle, on the border. Therefore, anything more than 5,8 is outside the circle and anything less is inside the circle.
[tex]\sqrt{-15}[/tex] = -3.87
[tex]\sqrt{-74}[/tex] = -8.60
(-3.87, -8.60)
Therefore, the answer is outside the circle...pretend the rectangle is a circle...as you can see point Z will be outside the circle.
I hope this helps!
Answer: A-Inside the Circle
Step-by-step explanation: For point Z: the coordinate is (-3.9,8.6) rounded to the nearest whole and since the center of the circle is at (0,0) and a point on the circle is (5,8) then we know that every other point will be the same distance away from the circle. If (5,8) is a point on the circle then (-5,8), (-5,-8), and (5,-8) will also be points. If you plot all of these and draw a circle outline you will see that point Z falls in the circle.

You have purchased 5 lottery tickets (each with different numbers) for tonight’s Pick 4. In the Pick 4, one ball (numbered 0 – 9) is drawn from each of four cylinders. What are your odds of winning?
Please help
Answer: 0.05%
Step-by-step explanation:
Ok, you have 5 tickets with different combinations of 4 numbers of them.
Now, the total number of combinations of 4 numbers (0 to 9) can be found as:
For the first number we have 10 options.
For the second number we also have 10 options.
for the third number we also have 10 options
for the fourth number we also have 10 options.
The total number of combinations is equal to the product of the number of options for each selection, this is:
Combinations = 10*10*10*10 = 100*100 = 10,000.
So out of 10,000 possible combinations, you have 5.
Then the odds of winning is the quotient between the combinations that you have and the total number of combinations: p = 5/10,000 = 0.0005
In percentage form, this is: 0.0005*100% = 0.05%

The steps for solving the equation 2x-3=7 are listed below
Answer:
2x-3=7
2x=10
x=5
Answer:
x=5
Step-by-step explanation:
To solve this equation, we need to find out what the variable, x, is equal to. In order to do this, we need to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind that everything must be done to both sides.
2x-3=7
3 is being subtracted from 2x. The opposite of subtraction is addition. Add 3 to both sides
2x-3+3=7+3
2x=7+3
2x=10
x is being multiplied by 2. The opposite of multiplication is division . Divide both sides by 2.
2x/2=10/2
x=10/2
x=5
