Simplify by combining like terms. 4 t-(t+3 t)
The simplification by combining like terms of 4t-(t + 3t) is 0.
According to the given question.
We have an expression 4t - (t+3t).
As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same. when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.
Since, we have to combine the like terms of the given expression 4t-(t+3t).
Here 4t, t and 3t both are the like terms.
So, we add and subtract coeffcients of t to simplify the given expression.
Therefore, the simplification of 4t - (t + 3t) is given by
4t -( t+ 3t)
= 4t - t -3t
= 4t - 4t
= 0
Hence, the simplification by combining like terms of 4t - (t + 3t) is 0.

MP = 29
Step-by-step explanation:
Given:
The entire line (MP) is equal to 5y + 9MN = 17NP = 3yMN + NP = MP
17 + 3y = 5y + 9
Find what y =____
17 + 3y = 5y + 9
subtract 9 from both sides
17 - 9 + 3y = 5y + 9 - 9
8 + 3y = 5y
subtract 3y from both sides
8 + 3y - 3y = 5y - 3y
8 = 2y
divided both sides by 2 to get y alone
8/2 = 2y/2
4 = y
Now plug in y to MP to find its length
5(4) + 9 = 20 + 9 = 29
MP = 29
To find NP, plug in y as well
3y = 3(4) = 12
NP = 12
Check:
MN + NP = MP

Kirsten thinks 24% of federal tax
dollars should fund education, and
Jackson thinks $0.35 of every tax
dollar should go toward education.
Express each as a rational number.
Who supports more education
funding?
Using rational numbers, Jackson supports more education funding as he 7/20 > 6/20.
What are rational numbers?Any number that can be expressed as a fraction and where the denominator (the bottom number) and the numerator (the top number) are both integers is considered a rational number. In other words, p/q, where p and q are both integers and q 0, can be used to represent a rational number.
According to Kirsten, 24% of federal tax dollars should fund education
⇒ 24% = 24 / 100
⇒ 6/25
According to Jackson, $0.35 of every tax dollar should go toward education
⇒ 0.35 = 35 / 100
⇒ 7/20
As we can infer that 7/20 > 6/20
So Jackson supports more education funding.

How much did he have left after 3 hours of jet ski riding?We know that Ricardo has $132.16, and he rents a jet sky that costs $20 plus $16.75 per hour.
So, the cost of renting the jet sky for x hours is given by the linear equation:
C(x) = $20 + x*$16.75
The cost of renting this for 3 hours is:
C(3) = $20 + 3*$16.75 = $70.25
Subtracting this from what Ricardo had:
$132.16 - $70.25 = $61.91

The initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively
How to find the initial amount and rate of change given a table for a linear function?The table of linear function represents the given parameter
On the table, we have the following points
(x, y) = (6, 467) and (10, 647)
The rate of change is calculated as
Rate = (y2 - y1)/(x2 - x1)
So, we have
Rate = (647 - 467)/(10 - 2)
Evaluate
Rate = 22.5
This means that the rate of change is $22.5
The initial amount is calculated as
y = m(x - x1) + y1
Where
m = 22.5
So, we have
y = 22.5(x - x1) + y1
Using one of the points, we have
y = 22.5(x - 6) + 467
Set x = 0
So, we have
y = 22.5(0 - 6) + 467
Evaluate

r + 3s = 7 , 2r - s = 7
By elimination, the solution of the system of equations, r + 3s = 7 and 2r - s = 7, is (r , s) = (4 , 1).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Using the elimination method, given two equations in r and s, a variable should be eliminated by adding/subtracting the two equations.
First, multiply the first equation by 2.
r + 3s = 7 ⇒ 2r + 6s = 14 (equation 1)
Subtracting the two equations will eliminate the variable r.
2r + 6s = 14 (equation 1)
2r - s = 7 (equation 2)
7s = 7
s = 1
Substitute the value of s to any of the two equations and solve for r.
2r - s = 7 (equation 2)
2r - 1 = 7
2r = 7 + 1
2r = 8
r = 4
Hence, the solution of the system of equations is (r , s) = (4 , 1).

What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to write and solve a system of equations that models this problem.To solve this question, we use the following representations:
x represents the fruit pies
y represents the fruit juice
A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
1.89x + 1.56y = 140.13 ---- the total cost
x + y = 82 --- the number of sales
Make x the subject in x + y = 82
So, we have
x = 82 - y
Substitute x = 82 - y in 1.89x + 1.56y = 140.13
1.89(82 - y) + 1.56y = 140.13
Expand
154.98 - 1.89y + 1.56y = 140.13
Evaluate the like terms
-0.33y = -14.85
Divide by -0.33
y = 45
So, we have
x = 82 - y
x = 82 - 45
