Martha ran a 5-kilometer race in 22.5 minutes what is Martha's unit rate
solve the following system
6x-3y=15
x+3y=-8
This system can be solved for x by elimination.
[tex]6x - 3y = 15\\ x + 3y = -8\\\\7x = 7\\\\x = 1[/tex]
Now, with what we found for x, we plug it back into one of the equations to solve for y. I chose the second one.
[tex]1 + 3y = -8\\\\3y = -9\\\\y = -3[/tex]
Now, we have our solution.
[tex](1, -3)[/tex]
Answer:
(1,-3)
Step-by-step explanation:
6x-3y=15
substitute x with 1 and y with -3
6(1)-3(-3)=15
6+9=15 so that's true
x+3y=-8
again substitute x with 1 and y with -3
(1)+3(-3)= -8
1-9=-8
-8=-8 and that's true
hope i helped

Step-by-step explanation:
The outside dimensions of a living room are 13' 0" x 22' 0". If the wall thickness is 5 1/8" , how many square feet of hardwood flooring are required for the living room floor? Allow 15% for waste A. 3,082 sq ft B. 295,35 sq ft C. 256.83 sq ft D. 3,432 sq ft
Answer:
B. 295,35 sq ft
Step-by-step explanation:
We are told that the outside dimensions of a living room are 13' 0" x 22' 0".
Since the wall has a thickness of 5 1/8", then the internal dimensions are;
Length = 22' 0" - 5⅛" - 5⅛" = 21' 1¾"
Width = 13' 0" - 5⅛" - 5⅛" = 12' 1¾"
The floor area will be length × width.
So let's convert length and width to feet
Length = 21' 1¾" = 21.1458 ft
Width = 12' 1¾" = 12.1458 ft
Area of floor required = 21.1458 × 12.1458 = 256.83
Allowing 15% for waste gives us;
Area provided = 256.83 × 1.15 = 295.35 Sq.ft

Answer:
7
Step-by-step explanation:
We have that x1=−1, y1=5, x2=3, y2=7.
Plug the given values into the formula for a slope: m=7−(5)3−(−1)=12.
Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).
b=5−(12)(−1)=112
Finally, the equation of the line can be written in the form y=b+mx:
y=112+x2

5 8 of a rectangle is coloured red. Damien cuts this red part into a number of pieces so that each piece is 1 16 of the whole rectangle. If the area of the rectangle is 48 square centimetres, what is the area of each piece?
Answer:
3 cm²
Step-by-step explanation:
Given that:
5/8 of rectangle = red
Let area of rectangle = x
Each piece = 1/16 of whole rectangle
Area of whole rectangle = 48 cm²
Area of each piece = 1/16 of 48
1/16 * 48cm²
= 48 / 16 cm²
= 3 cm²
Hence area of each piece = 3cm²
this equation has one soulution 5(x-1)+3x=7(x+1) what is the soulution
Answer:
X=6
Step-by-step explanation:
5(x-1)+3x=7(x+1)
5x-5+3x=7x+1
8x-5=7x+1
8x-7x=1+5
X=6
So the answer is X=6
What value of x would prove that lines I and M are parallel ?
Answer:
x = 17
Step-by-step explanation:
For the lines to be parallel, then
(8x - 31) and (6x + 3) are alternate angles and congruent, then
8x - 31 = 6x + 3 ( subtract 6x from both sides )
2x - 31 = 3 ( add 31 to both sides )
2x = 34 ( divide both sides by 2 )
x = 17

write an equation to find the number of ounces n in any number of pounds p
Answer:
B. [tex] n = 16p [/tex]
Step-by-step explanation:
number of ounces = n
number of pounds = p
There are 16 ounces in 1 pounds (unite rate: 1 pounds = 16 ounces)
Therefore, there would be n ounces in p pounds
Set a proportion to find n.
16 : 1 = n : p
[tex] \frac{16}{1} = \frac{n}{p} [/tex]
Multiply both sides by p
[tex] \frac{16}{1} \times p = \frac{n}{p} \times p [/tex]
[tex] \frac{16 \times p}{1} = n [/tex]
[tex] 16p = n [/tex]
[tex] n = 16p [/tex]

Problem: y-10=-3(x-2)
Answer:
Remove parentheses.
y-10=-3\times -2y−10=−3×−2
2 Simplify 3\times -23×−2 to -6−6.
y-10=-(-6)y−10=−(−6)
3 Remove parentheses.
y-10=6y−10=6
4 Add 1010 to both sides.
y=6+10y=6+10
5 Simplify 6+106+10 to 1616.
y=16y=16

The Smiths purchased 6 containers of ice cream for a party.
Each container holds 9 cups of ice cream
Before the party, their sons ate 3 cups of ice cream altogether
What fraction of the original amount ice cream purchased did the Smiths’ sons eat?
1. 1/3
2. 2/3
3. 1/18
4. 17/18
Answer: 17/18
Step-by-step explanation: Multiply the amount of containers and the amount of cups in each container. Subtract 3. This is 51 out of 54, simplify this and get 17 out of 18.
Answer:
the answer is 1/18
Step-by-step explanation:
6×9=54-3=51.
One third and two thirds are too large for the amount he ate, so is 17/18s.

Answer:
x = 8
Step-by-step explanation:
Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
So,
[tex] \rm \longrightarrow 45 \degree + 80 \degree + (9x - 17) \degree = 180 \degree \\ \\ \rm \longrightarrow 125 + 9x - 17 = 180 \\ \\ \rm \longrightarrow 108 + 9x = 180 \\ \\ \rm \longrightarrow (108 - 108) + 9x = 180 - 108 \\ \\ \rm \longrightarrow 9x = 72 \\ \\ \rm \longrightarrow \dfrac{9}{9} x = \dfrac{72}{9} \\ \\ \rm \longrightarrow x = 8[/tex]

Refer to the previous question.
Consider the four options from Question 2 that could be a good choice for Cal Amity's survey. Then, select the one that you think would work most effectively in this situation. Lastly, describe in detail how you would select the individuals in the survey sample. (Include details such as how you might split the population into groups and/or what process you would use to make sure the survey respondents are chosen randomly, etc.) Support your choice of a random sampling method by explaining why it would be most effective in reducing bias.
The previous question:Which type of sample would not be a good choice for Cal Amity's survey, because it is known to cause bias?
a convenience sample
a stratified sample
a systematic sample
a simple random sample
a cluster sample
Answer:
The correct approach is "a simple random sample".
Step-by-step explanation:
A simple random sample will become more efficient throughout this scenario because a sample of individuals becomes randomly generated from some kind of community so each individual has the same likelihood of someone being picked. This would contribute to the unpredictability as well as freedom of the experiments.Some other four approaches do never use any of certain characteristics. So that is indeed the best decision.

The number line shows the change in temperature from 7:00 a.M. To 1:00 p.M. Which expression shows how to find the difference between the temperatures at 7:00 a.M. And 1:00 p.M.?
Answer:
B
Step-by-step explanation:
The options in the question and the number line are shown in the image attached.
From the options, it is clear that the difference between the temperatures at 7:00 a.M. and 1:00 p.M is;
Temperature at 7:00 a.M - Temperature at 1:00 p.M
We can see from the number line that the temperature at 7:00 a.M = -4
Temperature at 1:00 p.M = 16
difference between the two temperatures = ∣(-4) - 16∣ = 20

Drag each number to the correct location on the equations. Each number can be used more than once, but not all numbers will be used. Roy and Elisa are buying tickets for the annual school concert. Roy buys 6 adult tickets and 2 child tickets for a total of $66. Elisa buys 5 adult tickets and 4 child tickets for a total of $62. Determine the system of equations that can be used to find the cost of one adult ticket, a, and the cost of one child ticket, c. 66 62 5 2 8 128 4 6
Answer:
a=$10
c=$3
Step-by-step explanation:
Step one:
given data
let adults tickets be a
and child tickets be c
so
Roy's purchase
6a+2c=66------1
Elisa's purchase
5a+4c=62-------2
Hence, the system of equations
6a+2c=66------1
5a+4c=62-------2
solving simultaneously
6a+2c=66------1 x2
5a+4c=62-------2 x1
12a+4c=132
-5a+4c=62
7a=70
divide both sides by 7
a=$10
put a=70 in 1
6(10)+2c=66------1
60+2c=66
2c=66-60
2c=6
c=$3
