A = 2p and B = 1/p are the values of a and b.
What does math division mean?
A number is divided in division, which is a straightforward procedure. The simplest way to conceptualize it is as a set of objects being distributed among a set of individuals, as in the example given above. Of course, in order to be fair, you should always pay each person the same amount.To divide this,
[tex]\frac{6p^{2} }{3p} = 2p[/tex]
Multiplying back through, we have
[tex]3p * 2p = 6p^{2}[/tex]
Subtracting this from the first term under the box, we have
[tex]6p^{2} - 6p^{2} = 0[/tex]
Bring down the next term, 9p.
See how many times 3p goes into 9p = 9p/3p = 3
Multiplying back through, we have 3(3p) = 9p.
Subtract this from the line above; 9p-9p = 0.
Bring down the last term, 3.
Since this is not 0, this is the remainder.
This gives us
2p + 3 R 3;
writing this as a rational expression, we have
2p + 3 + 3/3p
The remainder term 3/3p will simplify to 1/1p or 1/p;
this gives us
2p + 3 + 1/p
Therefore, the answer is A = 2p and B = 1/p

What in mathematics is a linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."Multiply both sides of the equation by a
coefficient - 2(4x - 3y ) = 11 × 2
3 ( 10x + 2y ) = ( - 1 ) × 3
apply multiplicative distribution law
8x - 6y = 11 × 2
3( 10x + 2y ) = (-1) × 3
calculate the first terms
8x - 6y = 22
3( 10x + 2y ) = ( -1) × 3
remove the parentheses
8x - 6y = 22
30x + 6y = -3
add up the two equation
8x - 6y + ( 30x + 6y ) = 22 + ( -3)
remove parentheses - 8x - 6y + 30x + 6y = 22 -3
cancel the unknown variables - 8x + 30x = 22 -3
combine like terms - 38x = 22 - 3
calculate the sum or difference - 38x = 19
reduce the greatest common factor on both
sides of equation - 2x = 1
divide both sides of the equation by the coefficient of variable - x = 1/2
substitute one unknown quantity into the elimination 8 * 1/2 - 6y = 22
reduce the expression to the lowest term 4-6y = 22
reduce the greatest common factor on both sides of the equation
2 - 3y = 11
Rearrange unknown terms to the left side of the equation - 2 - 3y = 11
calculate the sum or difference -3y = 9
reduce the greatest common factor on both sides of the equation -y = 3
divide both sides of the equation by the coefficient of variable y = -3
the solution set of the equations
x = 1/2
y = -3

Answer:
-96/7x or 13.714x
Step-by-step explanation:
-4/7+ 2/7x - 14x+4/7
first we do
4/7-4/7 which is zero, so we can cancel those out.
then we do
2/7x-14x ( or you can do -14x+2/7, it’s the same thing
use your calculator to make this easier. if you look you’ll be able to find a fraction button on most
after we do 2/7x-14x , we get -96/7x
if you want it in a fraction just divide and you’ll get -13.714x
A spherical tank has a capacity of 750 gallons. using the fact that 1 gallon is about 0.1337 ft3, find the radius of the tank (to the nearest hundredth of a foot).
The spherical tank with a capacity of 750 gallons has a radius of 2.88ft.
Volume refers to the total amount of space an object occupies. It also determines the capacity of the object.
Given the fact that 1 gallon is about 0.1337 ft^3, and the spherical tank has a capacity of 750 gallons, then it's volume or capacity can be converted from gallons to ft^3 by multiplying 750 with 0.1337.
1 gallon = 0.1337 ft^3
750 gallons = 750(0.1337 ft^3)
750 gallons = 100.275 ft^3
To solve for the radius of the spherical tank, use the formula for the volume of sphere given by the formula:
V = 4/3πr^3
where V = 100.275 ft^3
100.275 ft^3 = 4/3πr^3
r^3 = 23.93889288 ft^3
r = 2.882048957ft

The solution to the system of equations is (2.5, -2)
How to determine the solution to the system of equations?The system of equations is given as:
2x + y = 3
2x - 5y = 15
Subtract the equations to eliminate the variable x
This is represented as
2x - 2x + y - -5y = 3 - 15
Evaluate the like terms in the above equation
So, we have
y + 5y = 3 - 15
Evaluate the like terms in the above equation
So, we have
6y = -12
Divide both sides of the above equation by 6
So, we have
y = -2
Substitute y = -2 in 2x + y = 3
2x - 2 = 3
This gives
2x = 5
Divide by 2
x = 2.5

Left-handedness is _more_______ common than usual among mathematicians and ___more_____ common than usual among artist
The relationship between handedness and mathematical ability is still highly controversial.
While some researchers have claimed that left-handers are gifted in mathematics and strong right-handers perform the worst in mathematical tasks, others have more recently proposed that mixed-handers are the most disadvantaged group.
However, the studies in the field differ with regard to the ages and the gender of the participants, and the type of mathematical ability assessed.
To disentangle these discrepancies, we conducted five studies in several Italian schools (total participants: N = 2,314), involving students of different ages (six to seventeen) and a range of mathematical tasks.
The results show that (a) linear and quadratic functions are insufficient for capturing the link between handedness and mathematical ability; (b) the percentage of variance in mathematics scores explained by handedness was larger than in previous studies.
The last theory drawing a causal link from handedness to mathematical ability through cognition is the hemispheric indecision hypothesis.

The absolute-value equation to find Jason's max and min speeds is |x| = |55 ± 5| mi/h and the maximum speed is 60 mi/h and the minimum speed is 50 mi/h.
Absolute Value equation:
An absolute value equation in the form | ax + b | has the following properties:
If c < 0 , | a x + b | = c has no solution .
If c = 0 , | a x + b | = c has one solution .
If c > 0 , | a x + b | = c has two solutions .
Given,
Jason is driving his car at 55mi/h he needs to keep his car within 5 mi/h of his current speed.
Here we need to write solve an absolute-value equation to find Jason's max and min speeds.
We know that, the current speed = 55 mi/h
And he want to keep the speeds within 5 mi/h of his current speed.
Let x be the unit that measure the maximum and minimum speed.
So,
The maximum speed.
|x| = 55 + 5 = 60 mi/h

Please answer asap!!! Will give brainliest!!!!
Answer:
252
Step-by-step explanation:
One way we could think about this problem is by grouping the numbers together into pairs: -103+104 would be a pair, -105+106 would be a pair and et cetera up to the pair -199+200.
As you can see, each of these pairs add to 1 (-103+104=1, -199+200=1 etc.), so to solve this problem we can simply find how many of these pairs there are and multiply the number by 1 since each pair will total to 1.
To find how many pairs there are we need to find the number of numbers between 103 and 200 (incl.) and divide it by 2.
200-103= 97 numbers, adding 1 to count the one we started with gives us 98 numbers between 103 and 200 (incl.).
98/2 = 49 pairs of numbers. Since each pair totals 1, 1x49 is the total sum of all these pairs of numbers.
Now we need to address the other two numbers. The sequence started with 101+102 before we looked at the remaining pairs, so to find the sum, we just need to add together 101+102+49.
101+102+49 = 252
