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?
Answers
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.

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
Answers
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.

141x + 50 + 4x = 340
What is x?
Answers
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

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.
Answers
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.

Answers
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.

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.
Answers
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.
