Answer:
[tex]r=-3/5=-0.6[/tex]
Step-by-step explanation:
We have the equation:
[tex]6^{-3r}=6^{2r+3}[/tex]
Since their bases are the same, the exponents must be equivalent. So:
[tex]-3r=2r+3[/tex]
Solve for r, subtract 2r from both sides:
[tex]-5r=3[/tex]
Divide both sides by -5:
[tex]r=-3/5=-0.6[/tex]
So, the value of r is -3/5.
And we're done!

Find the slope of a pipe that slopes down 1/3 inch per foot
Answer:
-1/36
Step-by-step explanation:
The slope is of [tex]\mathbf{-\frac{1}{3}}[/tex]
----------------------
We use a linear function to understand this question, which has equation given by:
[tex]y = mx + b[/tex]
The slope is m, which is the rate of change, that is, how much y changes when x changes by 1.In this problem, for each foot, the pipe slopes down [tex]\frac{1}{3}[/tex] of an inch. Thus, the slope is [tex]m = -\frac{1}{3}[/tex]A similar problem is given at https://brainly.com/question/18594541

Answer: N= -1/4
Step-by-step explanation:
2 can go into 5 2 times which give you 2 wholes and you have 1 left over
Since you have 3/4 that extra one left would give you a whole because you can add it to the 3/4.
1 ft. = 12 in
Convert 4 feet to inches.
Convert 48 inches to feet.
Answer:
48 inches, 4 feet
Step-by-step explanation:
since each foot is 12 inches and we have 4 feet, we can multiply both numbers to convert 4 feet to inches. 12*4= 48 inches
to convert 48 inches to feet, we can divide by 12 since 12 inches is a foot. 48/12=4 feet

If you have 584 packages of hard candy to rebox for shipment to a discount store and you can pack 12 packages in each box, how many boxes will you need ?
Answer:
48.6666 round up to 49
Step-by-step explanation
do 584 divided by 12 equals 48.6666 then round up to 49
Answer:
49
Step-by-step explanation:
What you do is 584 divided by 12. That will give you 48.6666. You can’t have 48.6666 boxes so you round up. You will need 49 boxes.
A rectangle has an area of 171 square meters. Its width is ten meters less than the length. Find the measures of the length and width of the rectangle.
Step-by-step explanation:
The area of a rectangle is 171 m²
Let l is the length and b is the width of the rectangle
It width is 10 m less than the length. So,
b = l-10 ...(1)
Area of a rectangle is given by :
[tex]A=l\times b\\\\171=l(l-10)\\\\l^2-10l=171\\\\l^2-10l-171=0\\\\l^2-19l+9l-171=0\\\\\text{taking common together}\\\\l(l-19)+9(l-19)=0\\\\(l-9)(l-19)=0[/tex]
or
l = 9 m or l = 19 m
If l = 9 m,
b = 9-10 = -1 m (can't be possible)
If l = 19 m
b = 19-10 = 9 m
So, the length an the breadth of the rectangle is 19 m and 9 m respectively.

Which of these equations, when solved, gives a different value of x than the other three?
9.1 = -0.2x + 10
10 = 9.1 + 0.2x
10 – 0.2x = 9.1
9.1 – 10 = 0.2x
Answer:
D. 9.1 – 10 = 0.2x
Step-by-step explanation:
I got it right
The odd equation with a different value is equation d
Data;
9.1 = -0.2x + 1010 = 9.1 + 0.2x10 - 0.2x = 9.19.1 - 10 = 0.2xLinear EquationTo solve this problem, we have to solve each of the linear equations and get the value of x.
a)
[tex]9.1 = -0.2x + 10\\10 - 9.1 = 0.2x\\0.9 = 0.2x\\\frac{0.2x}{0.2} = \frac{0.9}{0.2} \\x = 4.5[/tex]
b)
[tex]10 = 9.1 + 0.2x\\0.2x = 10 - 9.1\\0.2x = 0.9\\\frac{0.2x}{0.2} = \frac{0.9}{0.2} \\x = 4.5\\[/tex]
c)
[tex]10 - 0.2x = 9.1\\-0.2x = 9.1 - 10\\-0.2x = -0.9\\x = 4.5[/tex]
d)
[tex]9.1 - 10 = 0.2x\\0.2x = -0.9\\x = -4.5[/tex]
The odd equation with a different value is equation d

What do you have to know about any segments and angles in a figure to decide whether the figure has line symmetry?
Answer:
Explained below.
Step-by-step explanation:
When drawing line of symmetry on a figure and reflecting, we have to know that pairs of segments in that figure must have the same length while pairs of angles must have the same measurement. This is to ensure that half of that figure must concise with the other half part of it when that figure is folded across a line of symmetry.
Solve the following system of equations.
6x -5y=13 & 9y-15+2x=0
x = 3
y = 1
Step-by-step explanation:Hi !
6x - 5y = 13
9y - 15 + 2x = 0
6x - 5y = 13
2x + 9y = 15 | ×(-3)
6x - 5y = 13
- 6x - 27y = - 45
add
6x - 6x - 5y - 27y = 13 - 45
- 32y = - 32 | ×(-)
32y = 32
y = 1
replace y = 1
6x - 5(1) = 13
6x - 5 = 13
6x = 13 + 5
6x = 18
x = 3
Good luck !
