3.407 miles

30.047 miles

30.047 miles

30.407 miles

Answers

15.235=5x
x= miles per day
your answer would be 3.047 miles

Answer:

3.047

Step-by-step explanation:

[tex]\frac{miles}{days} \\ \\\frac{15.235}{5} = \frac{?}{1} \\[/tex]

When solving equations you multiply the denominator of one of the fractions by the others numerator. Here the available numerator is 15.235 and the others denominator is 1. This means that we do 15.235 times 1, which is equal to 15.235. The next step is to divide by the remaining denominator or numerator. Here the remaining denominator is 5. This means that we divide 15.235 by 5 which is equal to 3.074.

Answer:

15. no

16. (a) yes; (b) no; (c) -2

Step-by-step explanation:

14. Try the value and see if the result is true:

3·2 -7 < 2 ⇒ -1 < 2 . . . . TRUE

h = 2 is a solution

15. Try the value and see if the result is true:

-12 +8 ≥ -12/4 ⇒ -4 ≥ -3 . . . . FALSE

q = -12 is not a solution

16. The inequalities can be solved for the solution set.

-2x < 10

x > -5 . . . . . divide by -2

and

-6 < -2x

3 > x . . . . . divide by -2

So, the solution set is ...

-5 < x < 3

a) x = 0 is a solution

b) x = 4 is not a solution

c) x = -2 is a solution

brainliest if right pls help

Answers

Answer:

Step-by-step explanation:

First of all -2-5= -7

It isn't (A) because (A) is saying that the beginning temperature was a postive number, which it wasn't The beginning temperature is -2, which is negative. So we can cross that off.

It isn't (B) because (B) is saying that you start off with -2 and then it gets warmer, and temperature adds up onto it. When you do -2 +5, you get 3, which is not the answer.

So, the answer is c

Proof: It starts of with negative 2, which is the first temperature. Then, it says decreased by 5, which is what is happening. 5 is getting subtracted from -2

So, the answer is C

Answer:

Step-by-step explanation:

-2-5

the minus sign infront of the two has to stay with the two so we would have -2°C the options we would be left with are b and c but since it says subtract 5 that would be a decreases not an increase so it would be decrease 5°C

THE STORY IS wrapping up a little bit of troubleI need help on 2,3, and 4... Read the diary entries.Nicholass Diary: April 2 and 3Friday, April 2Well, its only 10 more hours until my father and I leave for our treasure hunt. Every Saturday morning for as long as I can remember I have seen him leave, always by himself, to look for treasure. I have always longed to go with him, and hes always told me that someday I would get the chance. I was so excited when he told me I would finally have my chance that I was bouncing off the walls like a rubber ball and springing from one place to the next the rest of the day.He has always been as quiet as a mouse about the treasure that he finds, scurrying away with his equipment in the morning and piling up his treasure in his study. Even though he says he always comes home with something, he has never shown it to me or even told me what type of treasure it is. Is it gold, or silver, or maybe its precious jewels? Whatever it is, tomorrow I will find out, and hopefully hell let me bring some to class so that I can show my friends since Ive been bragging about it to them ever since Dad told me I could go!Saturday, April 3The treasure hunt was fun, but it was not what I expected. Dad and I left early in the morning and headed for the same woods that we sometimes go hiking in on Sundays. I never would have thought they hold treasure, but what was really odd was when Dad told me to leave the shovels at home because we wouldnt need them. But what he did bring with him was a bright yellow GPS . I had seen it in his truck many times before. I always wondered what he did with it. Today I found out.Dad and I wandered into the woods, first staying on the hiking path I had taken several times before and then veering off the path. The forest was like a statue; it was still and covered in damp moss and dead leaves; it didn't even seem alive. It appeared that no one had been there for a long time so I knew that this treasure must be old and far under the ground. How were we going to get to it without shovels?As Dad kept his eyes on the GPS , I looked around, and suddenly I noticed a patch of leaves that was disturbed and a log that looked like it had been moved. When I asked Dad about it, his eyes lit up, and he said he saw the treasure. He reached under the log and pulled out a plastic box with a label that read Official Geocache.I didnt know what an official geocache was, but I soon found out when Dad opened it. Inside was a little notebook and a bunch of small items like a set of dice, a toy car, and a large silver dollar. Dad said that he thought the toy car was cool, so he took it out and put it in his pocket and then pulled a golf ball from his other pocket and put it in the box. He wrote his name and my name in the little notebook and then closed the box and put it back where he found it.Geocaching, which is what Dad later told me this type of treasure hunting is called, was much different than digging for gold in the ground. But I thought it was fun, and I hope Dad takes me again next Saturday.Which sentence from Nicholass Diary: April 2 and 3 contains an analogy?"He has always been as quiet as a mouse about the treasure that he finds, scurrying away with his equipment in the morning and piling up his treasure in his study."hopefully hell let me bring some to class so that I can show my friends since Ive been bragging about it to them ever since Dad told me I could go!Is it gold, or silver, or maybe its precious jewels?
