Equivalent expressions are expressions of equal value.
The equivalent expressions of [tex]\mathbf{(\frac{r}{s})(6)} }[/tex] are [tex]\mathbf{\frac{3(6) - 1}{2(6) + 1}}[/tex] and [tex]\mathbf{ \frac{17}{13}}[/tex]
The expressions are given as:
[tex]\mathbf{r(x) = 3x - 1}[/tex]
[tex]\mathbf{s(x) = 2x + 1}[/tex]
[tex]\mathbf{(\frac{r}{s})(6)}[/tex] is calculated as follows:
We have:
[tex]\mathbf{(\frac{r}{s})(x) = \frac{r(x)}{s(x)}}[/tex]
Substitute expressions for r(x) and g(x)
[tex]\mathbf{(\frac{r}{s})(x) = \frac{3x - 1}{2x + 1}}[/tex]
Substitute 6 for x
[tex]\mathbf{(\frac{r}{s})(6) = \frac{3(6) - 1}{2(6) + 1}}[/tex]
Expand
[tex]\mathbf{(\frac{r}{s})(6) = \frac{18- 1}{12 + 1}}[/tex]
[tex]\mathbf{(\frac{r}{s})(6) = \frac{17}{13}}[/tex]
Hence, the equivalent expressions of [tex]\mathbf{(\frac{r}{s})(6)} }[/tex] are [tex]\mathbf{\frac{3(6) - 1}{2(6) + 1}}[/tex] and [tex]\mathbf{ \frac{17}{13}}[/tex]

Answers
Answer:
1. Fk = 24N, Fs = 60N
2. Fk = 60N, Fs = 84N
For 3, is it saying the car weighs 9000N? In that case, you’d convert Newtons to kg. then you’d find normal force by using Fn = mg (because Fn = mass x gravity) finally since you’ve found Fn, use Fk=ukFn and Fs=usFn to find kinetic and static friction.

Step-by-step explanation:
1/5 as a a decimal would be 0.20 because if you multiply 0.20 by 5 you get 1
Answer:
B
Step-by-step explanation:
First convert [tex]\frac{1}{5}[/tex] to a decimal : 0.2
y represents how many strawberries Zoe ate
x represents how many strawberries Nora ate
If you take the equation- y = 0.2x and plug how many strawberries Nora ate you would claculate how many Zoe ate.
For example: say Nora ate 10 strawberries the equation would be- y(how many strawberries Zoe ate) = 0.2 · 10 ( the naumber of strawberries Nora ate)

What is the slope of the line passing through (-3, 5) and (5,-3)?
Answers
the slope would be -1
Answer:
slope = -1
Step-by-step explanation:
slope = y2 - y1
x2 - x1
where (x1 = -3, y1 = 5)
(x2 = 5, y2 = -3)
= -3 - 5
5 - (-3)
= -8 / 8
= -1
What is the width of a rectangular prism that has a length of 4.5 feet, a height of 6 feet and a volume of 256.5 feet cubed? Please answer!
Answers
Answer:
9.5 feet
Step-by-step explanation:
To calculate volume, the formula is V = l*w*h.
We have the volume, length, and height, so we just need to plug it in to find the width. 256.5 = 4.5*w*6. Calculate this, and it'll become 256.5 = 27w. Then we divide both sides by 27 to find w. 256.5/27 = 27w/27. 9.5 = w. Width is 9.5 feet.

Andrea baked 3 cakes for her cousin's birthday. Each cake requires 3 1/4 cups of flour. How many cups of flour was left if she had 15 cups in the beginning? *
Answers
Answer:
5 1/4 cups of flour
Step-by-step explanation:
Each cake requires = 3 1/4 cups of flour
She has = 15 cups of flour
She made 3 cakes
Number of flour used for 3 cakes = 3 1/4 cups of flour × 3
= 13/4 × 3
= 39/4
= 9 3/4 cups of flour
Flour remaining = Total flour - used flour
= 15 - 39/4
= 60-39/4
= 21/4
= 5 1/4 cups of flour

Gary has turtles, cats, and birds for pets. The number of birds he has is 4 more than the number of turtles, and the
number of cats is 2 times the number of birds. Of the following, which could be the total number of Gary's pets?
A. 14
B. 18
C. 20
D. 22
E. 26
Answers
Answer:
b
Step-by-step explanation:
if the number of turtles is 2 then you add 4 birds so that is 6 then you times ti by 2 to get the number of cats
2:tutles
4:birds
12:cats
2+12+4=18
The total number of Gary's pets will be 18. Option B is correct.
What is an arithmetic operation?
Arithmetic is an area of mathematics involving the study of numbers and the different operations that can be performed on them. Addition, subtraction, multiplication, and division are the four basic math operations.
The number of birds he has is 4 more than the number of turtles,
y=x+4
c=2×b
if the number of turtles is 2 then you add 4 birds so that is 6 then you time by 2 to get the number of cats.
The total number of Gary's pets is found as;
T=2+12+4
T=18
The total number of Gary's pets will be 18.
Hence, option B is correct.

Last month, the online price of a powered ride-on car was $250. This month, the online price is $330. What is the percent of increase in the price of the car? Round the percent to the neartst tenth if necessary.
Answers
Answer: 32.0%
Step-by-step explanation:
The price of car last month = $250
The price of the car this month = $330
Increase in price = $330 - $250 = $80
Percentage increase = (Increase in price/Cost price last month) × 100
= $80$250 × 100
= 0.32 × 100
= 32.0%
The percent of increase in the price of the car is 32.0%.

Solve and show your work below: Julie And Paulo are building a treehouse. Julie has a wood board that is 1.15 meters long and Paulo has a board that is 0.7 meter long.What is the total length of the two boards ? Solve this problem any way you choose .
Answers
Answer: Total length of the two boards= 1.85 meters
Step-by-step explanation:
Given: For a treehouse
Length of first wooden board = 1.15 meters
Length of second wooden board = 0.7 meters
Then by using the addition operator
Total length = Length of first board + Length of second board
= 1.15 + 0. 7 meters
= 1.85 meters
Hence, the total length of the two boards = 1.85 meters
The slopes of the sides of quadrilateral ABCD are shown in the table below.
Which statement describes the relationship between the sides of the quadrilateral?
Answers
Answer:
B) AB is parallel to CD, but AD is not parallel to BC.
Step-by-step explanation:
The options are:
A) AD is parallel to BC, but AB is not parallel to CD.
B) AB is parallel to CD, but AD is not parallel to BC.
C) AB is parallel to CD, and AD is parallel to BC.
D) AD is not parallel to BC, and AB is not parallel to CD.
AB and CD have the same slope, so they are parallel.
BC and AD have different slopes, so they are not parallel.
Therefore, the answer is B.
