8r and 4r are like terms since they both have an r
also 3s and -3s are also like terms because of the s
how do I solve for N 1/2(n+4)=6?
Answer:
8
Step-by-step explanation:
Get rid of the denominator first. -Multiply both side by 2-
1/2 × 2 = 1 (n + 4) ----- n + 4
6 × 2 = 12
n + 4 = 12
Now solve for N
N = 12 - 4
N = 8

Find the equation of the line
PLEASE HELP
Answer:
y = -3x +7
Step-by-step explanation:
The equation for a line is: y = mx + b
m = slope
x = the x-value
y = the y-value
b = the y-intercept
Since the y-intercept is 7, we know the first part of the equation is: y = mx +7
Also, since the line is decreasing from right to left, m is going to be negative. A way to calculate the m is rise/run. Count how many blocks it is going horizontally (run)and how many blocks it is increasing/decreasing when going to the right (rise). Then divided the "rise" over "run". Another way is to choose two points. Now use the equation y1-y2/x1-x2,
or y2-y1/x2-x1. I am going to show using the equation.
My two points are (0,7) and (2,1)
change in y (rise):7-1 = 6
change in x (run): 0-2 = -2
6/-2 = -3. Your slope is -3. Now lets put it all together.
y = -3x +7
You can see that for every square moved to the right ONCE the y value is decreasing by 3 each time.

The perimeter of a patio is 64 feet. The length (L) is 10 feet longer than the width (W). What is the width of the patio?
9514 1404 393
Answer:
11 feet
Step-by-step explanation:
Let L and W represent the length and width of the patio. Then ...
L = W + 10
P = 2(L + W)
Substituting for the known values, we have ...
64 = 2((W +10) +W)
64 = 4W +20 . . . . simplify
44 = 4W . . . . . . . . subtract 20
11 = W . . . . . . . . . . divide by 4
The width of the patio is 11 feet.

Which of the following is an example of an improper fraction? a. 10/3, b.6/7, c. 4/5, d. 3/10
Answer:
A. 10/3
Step-by-step explanation
improper fraction examples;
[tex]\frac{12}{3}[/tex] [tex]\frac{10}{9}[/tex] [tex]\frac{11}{10}[/tex]
An improper fraction is a fraction that has a numerator bigger than the denominator, ( [tex]\frac{N}{D}[/tex] ), therefore the answer would be A.
Hope this helps
Final Answer: A. [tex]\frac{10}{3}[/tex]
Steps/Reasons/Explanation:
Question: Which of the following is an example of an improper fraction? a. 10/3, b.6/7, c. 4/5, d. 3/10
An improper fraction is a fraction that's numerator is greater or equal to its denominator. The correct answer would be A. [tex]\frac{10}{3}[/tex] because its numerator is greater than its denominator.

This is the last question from my questions before
Answer:
Just right the numbers they put
Answer:
see explanation
Step-by-step explanation:
Under a reflection in the line y = - x
a point (x, y ) → (- y, - x ) , thus
M(- 7, 1 ) → M'(- 1, 7 )
N(- 4, 1 ) → N'(- 1, 4 )
O(- 4, - 4 ) → O'(4, 4 )
P(- 7, - 4 ) → P'(4, 7 )

4x-5y=0
8x+5y=-60
what is the answer by substitution or elimination?
Use the figure below to determine what is RU
Answer:
20
Step-by-step explanation:
8x=6x+5 (subtract 6x from both sides)
2x =5 (divide by 2 both sides)
x=2.5
8x= 8*2.5 = 20 (substitute 2.5 for x)
or 6x+5 = 6(2.5)+5 = 20 (substitute 2.5 for x)

The sum of the speeds of two trains is 717.4 miles per hour. If the speed of the first train is 4.6 miles per hour faster than that of the second train, find the speed of each
Answer:
The second train speed is 356.4 miles per hour
And, the first train speed is 361 miles per hour
Step-by-step explanation:
The computation of the speed of each train is as follows
Given that
The Sum of the speed of two trains is 717.4 miles per hour
Let us suppose the second train speed be x
So for the first train, the speed is x + 4.6
Now the equation is
x + x + 4.6 = 717.4
2x + 4.6 = 717.4
2x = 717.4 - 4.6
2x = 712.8
x= 356.4
Therefore the second train speed is 356.4 miles per hour
And, the first train speed is = 356.4 + 4.6 = 361 miles per hour

Answer:
k = 2
Step-by-step explanation:
All of the triangles are similar, so the ratio of short side to long side is the same for all.
4/8 = k/4
k = 16/8 = 2 . . . . multiply by 4 and simplify
The value of k is 2.
