Answers
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

(y = 0.04x)
Can be put into form y = kx
(z/x = 9)

(5 = xy)
( x = y/2)
Step-by-step explanation:
y = kx
( y = 0.11x)
(y = 0.04x)
kx = y
(z/x = 9)

A farmer had 22.75 bushels of corn. He sold 12 2/5 bushels at the market. His three friends bought the remaining bushels of corn. If each person bought the same amount, how many bushels did each friend purchase?
Answers
Answer:
Each friend bought 3.45 bushels of corn.
Step-by-step explanation:
12 2/5 as a decimal is 12.40. You do 22.75 minus 12.40, which gives you 10.35. Next you do 10.35 divided by 3, which gives you your final answer of 3.45.

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
Answers
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.

if your multiply that by 10 then put the 10 next to variable, like usual. at least that's what I do.

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.
Answers
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. : )
