4.5.1) 2x-5y=8
x=3y-1
A. Substitute the equation that is already solved for one variable into the other equation.
B. Solve for the single variable in the one-variable equation.
C. Substitute the result from the previous step into x=3y−1 and solve for the unknown variable.
D. Write the solution as an ordered pair. E. Check the solution with the equation not used in Step C.
Answer: X=29
Step-by-step explanation:
First you substitute the x's: 2(3y-1)-5y=8
Then you open parenthesis:6y-2-5y=8
Combine like terms: y-2=8
Bring the 2 to the other side: y=10
Now you substitute the y with the answer: x=30-1
Easy equation: x=29

Suppose the average yearly prices for an ounce of gold during a 10-year period are as follows:
$279.90, $271.83, $310.52, $364.17, $410.51, $445.53, $604.25, $696.18, $872.75, $973.14
The mean is
The median is
Answer:the mean is because all the numbers added up are 5228.17 and then you divide by 10 because there is 10 numbers meaning that your mean is $522.89 the median is 425
Step-by-step explanation:
Answer:
mean price - $522.88
median price - $427.50
Step-by-step explanation:
$271.83 + $279.90 + $310.52 + $364.17 + $410.51 + $445.53 + $604.25 + $696.18 + $872.75 + $973.14 = 5,228.78 / 10 = 522.88
$271.83, $279.90, $310.52, $364.17, $410.51, $445.53, $604.25, $696.18, $872.75, 973.14 - there are two in the middle so find the average of the two = 427.50.
I tried to do this quickly, so let me know if there are any errors.

ITS NOT A OR B!!!! WILL GIVE BRAINLIEST!!!!!!Mia looked at a graph showing average global temperatures. She noticed that the average temperatures have risen abruptly over the past several decades. This indicates that global warming is occurring at a fast rate. What additional pieces of evidence do scientists use to support the idea that global warming is happening?
the amount of greenhouse gases leaving the atmosphere and increases in amounts of sea ice
the greenhouse effect and reductions in sea levels
greenhouse gas concentrations, decreases in amounts of sea ice, and increases in sea levels
ocean temperature changes, greenhouse gases concentrations, and harmful emissions reductions
B
but it could be C
put B
The additional pieces of evidence do scientists used to support the idea of global warming are greenhouse gas concentrations, decreases in amounts of sea ice, and increases in sea levels. Thus, option C is correct.
What is Global warming?Global warming is a type of climate change that refers to the long-term rise in global temperatures.
The concept that global warming is occurring is backed by rising greenhouse gas concentrations, decreasing sea ice, and rising sea levels.
The inability of reflected solar energy to go back to the area as a result of greenhouse gases creating a blanket over the atmosphere is said to be the cause of global warming.
Thus, a rise in greenhouse gas concentrations correlated with an increase in global temperature is one bit of evidence used to support the concept of global warming.
Furthermore, it seems natural that rising global temperatures will cause sea ice to melt and the ensuing water to rise. Hence, option C is correct.

Answer:
2nd answer/55
Step-by-step explanation:
Well, 1 and 3 are the same angle because they are vertical angles.
3,4,5 are supplementary angles.
3=35, 4=90, 5=c
90+35+c=180
125+c=180
125-125+c=180-125
180-125=c
c=55

On his way to the library , Jeff runs two blocks and then walks three more blocks.Sketch a graph to show the distance Jeff travels compared to time.
Answer:
Since I can't take a picture, I am going to explain how to draw it.
Step-by-step explanation:
When sketching the graph you must note if jeff is going up the y-axis and along the x-axis. In this case, run means he goes up every minute. So when jeff runs he is going up and 2 minutes have gone by. And when he walks he is going up 3 more but slower so it would double the time. Time would be on the x-axis and blocks would be labeled on the y-axis.
Hope this helps. : )

Step-by-step explanation:
An appropriate ratio for cups and pints is ...
(1 pint)/(2 cups) or (2 cups)/(1 pint)
The similar ratio involving the unknown will match the units of numerator and denominator to those of the unknown ratio:
[tex]\dfrac{1\text{ pint}}{2\text{ cups}}=\dfrac{4\text{ pints}}{x\text{ cups}}\\\\ \text{or}\\\\ \dfrac{2\text{ cups}}{1\text{ pint}}=\dfrac{9\text{ cups}}{x\text{ pints}}[/tex]
These formulations of the problem match the first and last choices: A and D.

10n-4=126
Step-by-step explanation:
I hope this is right, so number would be a variable (n) because we don't know what said number is.
if your multiply that by 10 then put the 10 next to variable, like usual. at least that's what I do.
four less would be saying to subtract 4
and the final answer is 126
