Step-by-step explanation:
A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. What was the temperature:
1 hour ago?
3 hours ago?
Half an hour ago?
Answer:
For one hour ago, it would be 3 C, 3 hours ago, it would be 9 C, and half an hour ago, it would be 1.5 C.
Step-by-step explanation: It's quite straightforward. Since the temperature is dropping, and you want to find the temp. of earlier times, just add 3C to every hour (1.5 for a half) it was ago, to what the temperature currently is now. (0 C).
Solve for m.
−48=12(m+4)
Enter your answer in the box.
Answer:
-8
Step-by-step explanation:
First, you distribute the right side
-48 = 12(m+4)
-48 = 12(m) + 12(4)
Simplify:
-48 = 12m+48
Solve for m
-96 = 12m
m=-8
Answer:
-8
Step-by-step explanation:
-48/12 = m+4
(-48/12) -4 = m
m = (-4) - 4
m = -8

A washing machine is filling up with water at a constant rate. The rate is Three-fourths of a gallon in 1 over 5 of a minute. Don calculated the unit rate to be 3 over 20 of a gallon per minute. What did he do wrong?
Answer:
First, you have to see how many gallons fill in a minute, obviously, so take 3/4 and divide it by 1/5, which gives 15/4. so you can see, don multiplied the two numbers instead of dividing, which is what he did wrong.Step-by-step explanation:
Answer from NukeExplosions1
Answer:
What he did wrong is that he multiplied the denominator wrong. it is supposed to be a 15. Don should re-calculate it to 3 over 15 of a gallon per minute.
hope this helped.

Nuha is 5 years older than her brother Cole. The sum of their ages is 37. How old is Nuha?
Cole age = x
Nuha age = x+5
x+x+5 =37
2x +5 =37
2x =32
x =16
Cole age = x = 16 yrs
Nuha age = x+5 =16+5 =21 yrs
So, she is 21!
Answer:
Nuha is 16
Step-by-step explanation:
x+x+5 =37
2x +5 =37
2x =32
x =16

Answer:
y=2x+6
I started with the simplist equation for the first set (0,6) of y=X+6 and then tested it out for the second set (1,8) which didn't work. I then ajusted it so it would work with the second set by doing y=2x+6. Lastly, I tested this equation with all of the points and it worked for them all.
Maria has already written Two-fifths of her 1,000 word essay. If she continues writing at the same pace of 6One-half words per minute, which expression shows the amount of time it will take her to write the rest of the essay?
1000 times two-fifths times 13/ 2
1000 times two-fifths divided by 13/ 2
1000 times three-fifths times 13 / 2
1000 times three-fifths divided by 13/2
Answer: B
Step-by-step explanation: Well use the process of elimination, there are no three-fifths in the equation so you can exclude options C and D, and then you take the remaining words left (600) and divide it by 6 and 1/2 to get how much time left. you wouldn't multiply it because that would increase the time which doesn't make sense.
Please help! This really doesn't make sense to me. I NEED HELP!!!!
Find the scale of the two similar sides with known dimensions:
45/27 = 1 2/3
Figure A is 1 2/3 times larger than B. Now multiply the similar side of B to find x:
x = 18 x 1 2/3
x = 30
Answer: x = 30
Answer: 30
Step-by-step explanation:
(This is a similarity question)
So,
X/18 = 45/27
Then cross multiplication
X= 45×18/ 27
X= 30
The Mongolian Giant Sunflower produces seeds that are over 1 inch long, grow up to 18 feet tall, and flowers that are 1 ½ feet wide. Each flower head produces 1,000 seeds. You decide to harvest the seeds at the end of the season so that you can sell them the following spring. If you save 8 flowers for harvesting, how many seeds is that? Write your answer in scientific notation.
Answer:
8*10^3
Step-by-step explanation:
The Mongolian Giant Sunflower produces seeds that are over 1 inch long, grow up to 18 feet tall, and flowers that are 1 ½ feet wide. - All of this information is useless, all the question is asking is how many seeds do 8 flowers produce.
Each flower head produces 1,000 seeds. If you save 8 flowers for harvesting, how many seeds is that? - 1000*8 = 8000. 8000 is scientific notation is 8*10^3, as 10^3=1000, and 1000*8=8000 seeds.
How do you decide where to shade an inequality whose boundary dose not go through the origin?
A. For <, shade above the boundary
B. If (0,0) is a solution, shade where (0,0) is
C. For >,shade below the boundary
D.If (0,0) is a solution, shade the boundary.
Answer:
I’m pretty sure that it is D because it says boundary and not just where it is at.
Step-by-step explanation:
If you have an equation for your graph you would substitute the y AND x with 0, you the solve the solution and if the solution is true then the space where (0,0) is located becomes the shaded area because that resembles the area in which everything is a positive solution with the equation. If it is false then the opposite area is then shaded because (0,0) doesn’t work with the problem.

141x + 50 + 4x = 340
What is x?
Answer:
x = 2
Step-by-step explanation:
141x + 50 + 4x = 340
=> 145x + 50 = 340
=> 145x = 290
=> x = 2
Hoped this helped.
Simplify both sides of the equation
141x+50+4x=340(141x+4x)+(50)=340(Combine Like Terms)145x+50=340145x+50=340Subtract 50 from both sides
145x+50−50=340−50145x=290Divide both sides by 145
[tex] = > \frac{145x}{145} = \frac{290}{145} [/tex]
x=2

Laura is training to run a race. She keeps track of the number of miles she runs. She has been training for 7 weeks, and she has run a total of 63 miles. At what rate has she been running, in miles per week?
Explanation:
You divide the two values given to get 63/7 = 9.
We can think of it as if it was a ratio 63 miles: 7 weeks. Dividing both parts of that ratio by 7 will turn the "7 weeks" into "1 week".
You can check the answer by multiplying the 9 miles per week with the 7 weeks to get 9*7 = 63 miles total.
