The length of a rectangle is (3x-2) and its width is (2x+1). Find algebraic expressions to represent both the perimeter and area of this rectangle
Answer:
Perimeter = 10x-2
Area = 6x²-x-2
Step-by-step explanation:
Perimeter=2L+2W
2(3x-2)+2(2x+1)
6x-4+4x+2
10x-2
Area=LW
(3x-2)(2x+1)
6x²+3x-4x-2
6x²-x-2
I need the ordered pair that represents the location of B
Answer:
( 9, -35 )
Step-by-step explanation:
We can figure out how far the midpoint is from point A and just add the same values to the midpoint's coordinates to get the location of point B.
From A to Midpoint in the X direction:
+ 6
From A to Midpoint in the Y direction:
-15
The coordinate of the midpoint is:
( 3, -20)
3 + 6 = 9
-15 + (-20) = -35
The coordinates of B are:
( 9, -35 )
Solve for g.

A train travels at a speed of 58.6 km/h. Express this speed in
a. m/s
b. cm/min
Answer:
16.27778 m/s
97666.6667 cm/min
Step-by-step explanation:
a. To convert km/hr into m/sec, multiply the number by 5 and then divide it by 18.
m/s = (58.6 * 5) /18 = 16.27778 m/s
b. 1 Kilometer/Hour = 1666.66666666667 Centimeter/Minute
so 58.6 * 1666.666 =97666.6667 cm/min
The library at school is organized by fiction and non-fiction books. There are 3 non-fiction books for every 7 fiction books. How many total books are there if the library has 240 non-fiction books?
Answer:
Total = 800 books
Step-by-step explanation:
It is given that,
In a library, there are 3 non-fiction books for every 7 fiction books. It means that the ratio of non-fiction books to the fiction books is 3:7.
There if the library has 240 non-fiction books.
Let non fiction books are 3x and fiction books are 7x.
ATQ,
3x=240
x=80
Fiction books = 7x = 7(80) = 560
Total no of books = fiction books + non-fiction books
= 240 + 560
=800
Hence, the total no of books are 800.

Answer:
Step-by-step explanation:
if Charles bought the sneakers for 6.30 and wants to re-sell them with 40% more,
first lets see how much is 40% of 6.30
(6.30*40)/100=2.52
he will resell the shoes with
6.30+2.52=8.82
Answer:

If 9(1-x) = 27Y and x-y=-11/2, find the value of x + y.
Answer:
-2.25
Step-by-step explanation:
9(1-x) = 27Y
9-9x =27y
-9x -27y = -9 multiply all terms by -1
9x +27y =9 equation (1)
x-y= -11/2 equation (2)
by solving 2 equations
x= -3.875
y= 1.625
∴ x+ y = 1.625 +(-3.875) = -2.25
Can someone write the process and solution please?
Answer:
A
Step-by-step explanation:
We can get this by simplifying the inequalities
3(x-4) ≤ 18
3x - 12 ≤ 18
3x ≤ 18 + 12
3x ≤ 30
x ≤ 30/3
x ≤ 10
Secondly;
2(x-1) ≥ 6
2x - 2 ≥ 6
2x ≥ 6 + 2
2x ≥ 8
x ≥ 4
So the possible answer that fits both cases is 9
12 won’t work as it is not less than 10; we need an answer that is less than 10 to satisfy the first inequality

5. A train travels two different routes: the North Route and the South Route. • On Monday, the train traveled the North Route 8 times and the South Route 10 times, traveling a total of 410 miles. • On Tuesday, the train traveled the North Route 15 times and the South Route 11 times, traveling a total of 575 miles. How long is each route?
Answer:
North Route is 20 miles, and South Route is 25 miles.
Step-by-step explanation:
Let the length of the North route be represented by x and that of the South route be represented by y.
On Monday,
8x + 10y = 410
On Tuesday,
15x + 11y = 575
So that,
8x + 10y = 410 .............. 1
15x + 11y = 575 ......... 2
Using substitution method, from equation 1;
x = [tex]\frac{410 - 10y}{8}[/tex] ................. 3
Substitute the expression for x into equation 2,
15([tex]\frac{410 - 10y}{8}[/tex]) + 11y = 575
multiply through by 8,
6150 - 150y + 88y = 4600
6150 - 62y = 4600
6150 - 4600 = 62y
1550 = 62y
divide through by 62 to have,
y = 25
Substitute the value of y in equation 3
x = [tex]\frac{410 - 10y}{8}[/tex]
= [tex]\frac{410 - 10(25)}{8}[/tex]
= 20
x = 20
Thus, North Route is 20 miles, and South Route is 25 miles.
Use the scatter plot to fill in the missing coordinate of the ordered pair.
Answer:
(16, 6)
Step-by-step explanation:
The coordinate of an ordered pair is often represented as (x, y). That is, when x is equal to a particular value, the value of y would be the corresponding value to x on the coordinate plane.
So, given an incomplete ordered pair, (16, ), to find the missing coordinate, trace the value of y that corresponds to the value of x = 16.
That is, what is the value of y when x = 16.
From the plot, when x = 16, y = 6. The missing coordinate is 6.
Thus, we would have:
(16, 6).

Combining Like TermsStep-by-step explanation:
Step 1: Define Equation
2x + 3 + 4x = 6x + 3
Step 2: Solve for x
Combine like terms: 6x + 3 = 6x + 3Subtract 3 on both sides: 6x = 6xDivide 6 on both sides: x = xHere we see that x does indeed equal to x.
∴ x = infinite amount of solutions.
2x + 3 + 4x = 6x + 3
Combine the like terms on the left side
2x + 4x = 6x
6x + 3= 6x + 3
Subtract 3 from each side
6x = 6x
Divide each side by 6
x = x
No matter what x is, they are the same. It has infinite solutions.

The measures of the angles of a triangle are shown in the figure below. Solve
for x.
Answer:
[tex]x = 46[/tex]
Step-by-step explanation:
Given
The three angles in the triangle are: x, 34 and 100
Required
Determine the value of x
Angles in a triangle add up to 180.
So, we have:
[tex]x + 34 + 100 = 180[/tex]
[tex]x + 134 = 180[/tex]
Subtract 134 from both sides
[tex]x + 134 - 134 = 180 - 134[/tex]
[tex]x = 180 - 134[/tex]
[tex]x = 46[/tex]
Hence, the measure of x is 46

The formula for the area of a trapezoid is A = [tex]\frac{a+b}{2} h[/tex] where a and b are the bases and h is the height of the trapezoid.
In this case, the numbers that will be replacing a and b will be 4 and 7, making the equation look like this: A = [tex]\frac{4+7}{2}h[/tex] .
Now, you have to determine the height of the trapezoid, which in this case is 4 units. The equation will now look like this: A = [tex]\frac{4+7}{2}4[/tex].
You can solve from here like so:
A = [tex]\frac{11}{2}4[/tex]
A = 5.5(4)
A = 22

Jada has 12 library books checked out and Han has 1/3 less than that. How many books does Han have checked out?
The total book checked out by Han will be equal to 8 which is 4 less than Jada.
What is an arithmetic operation?The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.
As per the given information in the question,
Total books checked out Jada = 12
Han has 1/3 less than Jada so,
12 × 1/3
= 4 books less than Jada.

Answer:
C) 115 degrees
Step-by-step explanation:
A line is 180 degrees.
This means that the other side of the line with an angle of 115 degrees will be 180-115=65 degrees.
The angle above that will be 115 and the other will be 65.
Line v is similar to line u. This means that it is 115 degrees because the question mark is at the spot that is 115 degrees in the above angles.

The negative means you flip it
1/7^2 times 7^6 is 7^6/7^2 (just multiply).
using rules of exponents, 7^6/7^2 is 7^4 (just subtract 2 from 6)
D is the only one that equals 7^4, as 2 times 2 is 4.
