Eliza and Arielle are running on a track. Eliza ran 100 meters in 20 seconds. Arielle ran 150 meters in 35 seconds. Who ran faster?
Answer:
Step-by-step explanation: eliza ran 5 and 4.285714286
soooo eliza
Answer:
Eliza
Step-by-step explanation:
Calculate each of their speeds in like terms, then compare to find out who ran faster.
Eliza's speed = distance / time = 100 meters / 20 seconds = 5.0 meters / second
Arielle's speed = distance / time = 150 meters / 35 seconds = 4.3 meters / second
Eliza's speed is 5.0 meters / second, which is faster than Arielle's speed of 4.3 meters / second.
Therefore, Eliza ran faster.
Can someone please answer this for me?
Hello:
--> let's consider what the question asks for:
--> solve the system of equations
As the equations are written:
--> they set functions of x equal to y
--> let's set both functions of x equal to each other as they are both
equal to y
[tex]4x-3=-2x+9\\4x+2x=3+9\\6x=12\\x=2[/tex]
Since x = 2:
--> let's find 'y' by plugging x into either equation
[tex]y=4x-3=4(2)-3=8-3=5[/tex]
Answer: (2,5) or x = 2 & y = 5
Jan had $219 in her savings account she withdraws $6 a week to buy lunch. Assuming she does not deposit any more money. Write a linear function to represent how much money (y) jan will have after x weeks
Answer:
y = 219 -6x
Step-by-step explanation:
The money she will have remaining (y), will be the amount of money she started with subtracted by the amount of money spent each week multiplied by the number of weeks (x)

Calculate the markdown when the original cost is $1.75, the markdown is 20%.
Markdown amount:
Retail price:
Answer:
Markdown price: $0.35
Retail price: $1.40
Step-by-step explanation: First, let's find and use the formula for a markdown:
20% can also = 1/5
So, we can do this in 2 ways:
(1st way): Part percent * whole number / 100
Plug in the numbers:
1.75 * 20 / 100
= 0.35
Or:
1.75 / 1/5
=0.35
Now, subtract 0.35 from 1.75, and you get $1.40 as your retail price. I hope this helps! Can you please mark me as brainliest?

Which of the following tables represents a linear relationship that is also proportional?
x −1 0 1
y −3 −2 −1
x −2 0 2
y −3 0 3
x −2 0 2
y 0 2 3
x −2 0 2
y 2 4 6
The table that represents a linear relationship that is also proportional is:
x - 2 0 2
y - 0 2 4
This is because the ratio between y and x is constant, which is the definition of proportionality. In this case, the ratio is 0/(-2) = 2/0 = 4/2 = 0, which is undefined but still a constant. The other tables do not have a constant ratio between y and x.
Which of these can be expressed as a power of 5? Please show the steps
A) 22 + 32
B 5 + 5 + 5 + 5 +5 + 5
C) 4 × 4 × 4 × 4 × 4
D) (7 - 2) × (7 - 2) × (7 - 2)
Answer: C
Step-by-step explanation:
C because it is 4 x 4 x 4 x 4 x 4 (or 4 times itself 5 times).
The required expression that can be expressed in the power of 5 is 4 × 4 × 4 × 4 × 4. Option C is correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
A)
22 + 32 = 54
Cannot be expressed as a power of 5
Similarly, B 5 + 5 + 5 + 5 +5 + 5 and D) (7 - 2) × (7 - 2) × (7 - 2) cannot be expressed in the power of 5
But,
(C) 4 × 4 × 4 × 4 × 4, can be expresses in power of 5,
4 × 4 × 4 × 4 × 4 = 4¹⁺¹⁺¹⁺¹⁺¹⁺ = 4⁵
Since in multiplication of the common number is equal to that number sum of the exponents such as a×a = a²
Thus, the required expression that can be expressed in the power of 5 is 4 × 4 × 4 × 4 × 4. Option C is correct.

The equation that relates the flow of water through a 8-inch pipe to a 6-inch pipe is y = .
What is the equation?
Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.
In order to determine the equation, divide the flow of water through a 8-inch pipe by the flow of water through a 6-inch pipe
1600 / 260 = y = 6 12/13 f
