Write an expression for the perimeter of the triangle shown below:

A triangle is shown with side lengths labeled 2.3x plus 14, 2x, and negative 0.2x plus 15.

4.1x + 29
4.1x − 29
4.5x + 29
4.5x − 29

Answers

Answer 1

Answer:

4.1x + 29

Step-by-step explanation:

1. Combine like terms (2.3x + 2x= 4.3x - 0.2x = 4.1x)

2. add the 14 + 15 = 2

That gives you the equation 4.1x + 29

I also took the test so I know I it's right ;)

A jewelry maker is designing a crown. The crown must have at least 45 gems, using only emeralds, rubies, and diamonds. The number of rubies must be 1 less than 3 times the number of emeralds. The number of diamonds must be 4 less than the number of rubies. Which inequality could the jewelry maker use to find the fewest number of emeralds, x, that can be placed on the crown?

Answers

Answer:

Step-by-step explanation:

X is the variable and x means multiplication symbol.

X + (X x 3 - 1) + (X x 3 - 1) - 4) ≥ 45 is the answer I got.

The answer to that inequality would be

X ≥  7 I think

The variables y and x have a proportional relationship, and y = 28 when x = 21.



What is the value of x when y = 42?


x = 14

x = 1823

x = 3112

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.

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.

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

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.

Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!

Answers

Answer:

Step-by-step explanation:

To calculate the speed of each one we proceed as follows:

speed=distance/time

a] Noah's speed:

distance=2.5 miles

time=3/5 hours

speed=(2 1/2)/(3/5)

=(5/2)/(3/5)

=5/2×5/3

=25/6

=4 1/6 mi/hr

Emily's speed

distance=3 3/4 miles

time=5/6 hour

thus

speed=(3 3/4)/(5/6)

=15/4)/(5/6)

=15/4×6/5

=4 1/2 mi/hr

Anna's speed:

distance=3 1/3 miles

time=3/5

speed=(3 1/3)/(3/5

=(10/3)/(3/5)

=10/3×5/3

=5 5/9 mi/hr

Anna was the fastest

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

The answer will be x=29

He had already had as much supper as he could hold; also he had had lots of beer. 'Poor little blighter! Let him go!' 'Not till he says what he means by lots and none at all,' said Bert. 'I dont want to have me throat cut in me sleep! Hold his toes in the fire, till he talks!' 'I wont have it,' said William. 'I caught him anyway.'" "The day grew lighter and warmer as they floated along. After a while, the river rounded a steep shoulder of land that came down upon their left Suddenly the cliff fell away. The shores sank. The trees ended. Then Bilbo saw a sight: The lands opened wide about him, filled with the waters of the river which broke up and wandered in a hundred winding courses." "'No time now! said the hobbit. You just follow me! We must all keep together and not risk getting separated. All of us must escape or none, and this is our last chance. If this is found out, goodness knows where the king will put you next with chains on your hands and feet too, I expect. Dont argue. Theres a good fellow.'" "'Half a moment!' cried Bilbo, who was still thinking uncomfortably about eating. Fortunately he had once heard something rather like this before, and getting his wits back he thought of the answer. 'Wind, wind of course,' he said, and he was so pleased that he made up one on the spot. 'Thisll puzzle the nasty little underground creature,' he thought: An eye in a blue face Saw an eye in a green face.
