Answer:
x=-5
Step-by-step explanation:
First, you have to cross multiply.
2*2x+3 1*3x+1
4x+6=3x+1
Then, you subtract 3x from both sides.
4x+6=3x+1
-3x -3x
x+6=1
Next, you subtract 6 from both sides.
x+6=1
-6 -6
x=-5
Answer:
x = -5 (process below)
Step-by-step explanation:
1) To solve this easily, you can cross multiply. Multiply the numerator of the first fraction with the denominator of the second fraction, and multiply the denominator of the first fraction with the numerator of the second fraction:
[tex]\frac{2}{3x+1} = \frac{1}{2x+3} \\2(2x +3) = 1(3x + 1)\\4x + 6 = 3x + 1[/tex]
2) Next, isolate x to find its values. Subtract both sides by 3x.
[tex]4x + 6 = 3x +1\\x + 6 = 1[/tex]
3) Finally, subtract both sides by 6.
[tex]x + 6 = 1 \\x = -5[/tex]

What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
To calculate the total length of fencing Mark needs to surround all four gardens, we first need to determine the perimeter of one rectangular garden.
The perimeter of a rectangle is given by the formula:
P = 2l + 2w,
where P is the perimeter, l is the length, and w is the width.
For one rectangular garden with a length of 60 feet and a width of 43 feet, the perimeter would be:
P = 2(60) + 2(43) = 120 + 86 = 206 feet.
Therefore, to surround all four gardens, Mark would need a total of:
4 x 206 feet = 824 feet of fencing.
Thus,
Mark would need a total of 824 feet of fencing to surround all four rectangular gardens.

The equation k = 1.6d gives an approximate relationship between d miles and k kilometers. The distance between Boise, Idaho, and Reno, Nevada, is 430 miles. Express the distance in kilometers.
A.
431.6 km
B.
268.8 km
C.
688 km
Answer:
B
Step-by-step explanation:
Answer:
The answer is C. 688 km
Step-by-step explanation:
you do is multiply the miles x 1.6 and you will get k. so 430miles x 1.6 = 688k
and 665miles x 1.6 = 1064k
1 Mile is 1,6 Kilometers
430 Miles = 688 Kilometers (430 * 1,6)
665 Miles = 1064 Kilometers (665 * 1,6)
1. if you want your questions answered, don't whine -- just ask the question. for example, in this you haven't really asked anyone the question. They have to assume what you are trying to find out.
2. It is simple math if you understand the equation you gave:
You are solving for "k" which is kilometers;
You have been given the distance which is "d" in miles (430 miles and 665 miles)
The equation means: "k" equals 1.6 times the value of "d"
so the answers to your implied questions are:
k = 430 x 1.6 = 688 kilometers
k = 665 x 1.6 = 1064 kilometers
You might also asking your question in a more appropriate category. this is more of a math problem than a geography question (the names of the cities is irrelevant to the answer; the relevant part is the distance in miles).
The number of kilometers is ALWAYS greater than the corresponding miles. For example 1 mile = 1.6 km, so there is no way that when you convert miles to kilometers you will ever come up with a lower number of kilometers than the miles.

x=4y-1
x+2y=11
Answer:
x = 7, y = 2
Step-by-step explanation:
x= 4y -1
since x is by itself 4y-1 will substitute for x in the other equation x+2y=11
it will become 4y-1+2y=11
+1 +1
add one to both sides since is doesn't have a variable.
it will become 4y+2y= 12 now add 4y+2y
becomes 6y=12

Identifying the slope, y-intercept and x- intercept of each
Answer:
slope= -3
y-intercept= 6
Step-by-step explanation:
1. Approach
To solve this problem, one needs the slope and the y-intercept. First, one will solve for the slope, using the given points, then input it into the equation of a line in slope-intercept form. The one can solve for the y-intercept.
2.Solve for the slope
The formula to find the slope of a line is;
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where (m) is the variable used to represent the slope.
Use the first two given points, and solve;
(1, 3), (2, 0)
Substitute in,
[tex]\frac{(0)-(3)}{(2)-(1)}[/tex]
Simplify;
[tex]\frac{-3}{1}\\\\=-3[/tex]
3. Put equation into slope-intercept form
The equation of a line in slope-intercept form is;
[tex]y = mx + b[/tex]
Where (m) is the slope, and (b) is the y-intercept.
Since one solved for the slope, substitute that in, then substitute in another point, and solve for the parameter (b).
[tex]y=-3x+b[/tex]
Substitute in point (3, -3)
[tex]-3=-3(3)+b\\-3 = -9 + b\\6 = b[/tex]

Robert purchased a 2010 model sedan for $16,000. The dealership offered
him a $99/month payment for 60 months, after which the unpaid balance is
due. If the interest rate is 6%, find the balloon payment due at the end of 60
months.
O
A. $17,513.12
O
B. $15,000
C. $18,153.21
O
D. $14,674.37
Answer:
The correct option is D. $14,674.37.
Step-by-step explanation:
This can be calculated using the ballon payment formula as follows:
P = (PV - (Ballon / (1 + r)^n)) * (r / (1 – (1 + r)^-n)) ...................... (1)
Where:
P = Monthly payment = $99
PV = present value of the loan or the purchase price of the 2010 model sedan = $16,000
Ballon = Ballon payment due at the end of 60 months = ?
r = monthly interest rate = 6% / 12 = 0.06 / 12 = 0.005
n = number of periods or months = 60
Substituting the values into equation (1) and solve for Ballon, we have:
$99 = ($16,000 - (Ballon / (1 + 0.005)^60)) * (0.005 / (1 -(1 + 0.005)^-60))
$99 = ($16,000 - (Ballon / 1.3488501525493)) * 0.0193328015294284
$99 / 0.0193328015294284 = ($16,000 - (Ballon / 1.3488501525493))
$5,120.83051436193 = $16,000 - (Ballon / 1.3488501525493)
Ballon / 1.3488501525493 = $16,000 - $5,120.83051436193
Ballon / 1.3488501525493 = $10,879.1694856381
Ballon = $10,879.1694856381 * 1.3488501525493
Ballon = $14,674.3694203126
Rounding to 2 decimal places, we have:
Ballon = $14,674.37
Therefore, the correct option is D. $14,674.37.
Choose the two expressions that are equivalent to 5. 75 ÷ 1. 15
A: 575 ÷115
B: 5,750 ÷ 1,150
C: 5,750 ÷ 115
D: 575 ÷ 1,150
Answer:
A and B, but I’m gonna explain it the best I can too.
Step-by-step explanation:
5.75 divided by 1.15 is the same as answer A, since all you are doing is taking away the periods, making it whole numbers.
Again 5.75 divided by 1.15 is the same as B as well, Since it is the same just without the periods and an added zero at the end of each.
This Is so that they are both all equivalent by being whole numbers, but whatever you do to one numbers in the expression that you think is the answer you have to do to the other numbers in the expression
they have to add up completely the same.

I'm not sure if this is exactly right because the wording of the problem is confusing.
Answer:
a) Number of square feet of wallpaper for bedroom = 12x^2 - 21
b) Number of square feet of wallpaper for living room = 14x^2 - 42
c) Total amount of wallpaper needed = 26x^2 - 63
d) 107 more sq ft of wallpaper will be needed for the living room than bedroom.
Step-by-step explanation:
a) First find the area of each wall.
Length: 3x, Width: 3x, Height: x
(3x × x) + (3x × x) + (3x × x) + (3x × x) = 3x^2 + 3x^2 + 3x^2 + 3x^2 = 12x^2
12x^2 represents the amount of wallpaper needed, including the door. Find the area of the door and subtract it from this value.
3 × 7 = 21
12x^2 - 21 = Total sq ft of wallpaper needed for bedroom
b) First find the area of each wall.
Length: 4x, Width: 3x, Height: x
(4x × x) + (4x × x) + (3x × x) + (3x × x) = 4x^2 + 4x^2 + 3x^2 + 3x^2 = 14x^2
14x^2 represents the amount of wallpaper needed, including the door. Find the area of both doors and subtract it from this value.
3 × 7 = 21 × 2 = 42
42x^2 - 42 = Total sq ft of wallpaper needed for living room
c) Add the two expressions to find the total amount of wallpaper needed.
(12x^2 - 21) + (42x^2 - 42) = 26x^2 - 63
26x^2 - 63 = Total sq ft of wallpaper needed for both rooms
d) Plug x = 8 into the equations found in part a and b.
12(8)^2 - 21 = 747
14(8)^2 - 42 = 854
Subtract these answers to find the difference in amount.
854 - 747 = 107
The living room needs 107 sq ft more of wallpaper than the bedroom
