Solve the following equations. Check your work
-5x + 3 = 2x - 1
Answer:
Step-by-step explanation:
-5x+3 = 2x -1
-5x + 3 +1 = 2x
4 - 5x = 2x
4 = 7x
x = 4/7
To check work, we must plug back the value we got into our equation and make sure that both sides are equal to each other.
-5(4/7) + 3 = 2(4/7) -1
1/7 = 1/7
I got 1/7 i don't know if that's right, so please tell me

Distinguish between different kinds of cardiorespiratory fitness assessments and explain why different tests provide different information about fitness levels.
Answer:
There are several different kinds of assessments of cardiorespiratory fitness such as timed runs, timed walks, and step tests. The different tests assess the use of different muscle groups as well as different levels of exertion. Running is more intensive than walking, and walking for a mile at a steady pace over level ground uses different muscle groups than stepping up and down repeatedly. Using multiple, different fitness assessments gives a more complete picture of the various factors that contribute to an individual's level of cardiorespiratory fitness.

A student wants to find the answer to the question “What is the most popular restaurant in Bedford?” He asks 20 randomly selected customers at one local restaurant. Which best describes the accuracy of the results of the survey? The survey results will be accurate since the sample was chosen randomly. The survey results will be inaccurate since the entire population should have been surveyed. The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant. The survey results will be accurate since the sample represents the population and the population is the target of the survey.
Answer:
The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant.
Step-by-step explanation:
When doing a survey you must make sure it is unbiased by asking a variety of people for example if you are wondering what is the favorite class at school you have to ask a certain amount of people from each class because if you ask only people from P.E the answer more than likely will be P.E or if u ask 3 people from Art and 17 from P.E your answer will properly be P.E. Make sense?
Answer:
The correct answer is C. The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant.

Cora got a $1200 loan for 2 years. She paid $90 in interest. What was her interest rate? (*hint: you will get a decimal as an answer that needs to be turned to a %). SOS I NEED THIS VERY QUICK
Answer:
4%
Step-by-step explanation:
Formula - l/Pt=r
l=intrest amount paid in a specific time period, 90
P = Principle amount(before intrest), 1,200
t = Time period involved, 2 years
r = Interest rate in decimal,
90/1,200*2 , 90/2,400 = 0.0375 = 0.04 = 4%

Cost of Bananas
Bananas (x)
Cost in dollars (y)
1
0.27
2
0.54
3
0.81
4
1.08
On a coordinate plane, the x-axis is labeled bananas and the y-axis is labeled cost in dollars. The line goes through points (1, 0.27) and (2, 0.54).
Which statement about the graph is true?
The number of bananas is the independent variable, and the cost in dollars is the dependent variable.
The point (1.35, 5) is on the line.
The number of bananas is graphed on the y-axis, and the cost is graphed on the x-axis.
The two variables are the number of bananas and the cost of one banana.

Step-by-step explanation:
Jim currently has $1,250 in his bank account and Sally has $1,400 in her bank account. Jim deposits $27.50 per week and Sally deposits $20 per week into her account. After how many weeks will they have the same amount of money?
After 20 weeks, they will have the same amount of money.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
Given data as:
Jim's current balance is $1250.
Sallybhas's current balance = 1400$
Jim makes a weekly deposit of $27.50.
sally's deposits per week = $20
We have to determine number of weeks they will have the same amount of money.
Let w be the week. after w weeks, they have the same amount
According to the given situation, the required solution would be :
⇒ 1250+27.50w = 1400+20w
⇒ 27.50w-20w = 1400-1250
⇒ 7.5w = 150
⇒ w = 150/7.5
Apply the division operation,
⇒ w = 20
As a result, after 20 weeks, they will have the same amount of money.

can someone help me out and answer this two questions :P
Answer:
Question 1: 367.5 ft squared
Question 2: 21.6 miles
Step-by-step explanation:
Answer:
11. 367.5 sqft 12. 21.6 sqmiles
Step-by-step explanation:
Well for 11. if each inch is 3.5 feet then you would wan t to multiply 5 and 6 by 3.5. You get 17.5 and 21. To find area, you'll have multiply the height and width which is 17.5 and 21. Once you do that you end up with 367.5ft squared.
For 12. each inch is 4.8 mines and there are 4.5 inches. So you want to do 4.5 times 4.8 which gives you 21.6 square miles. I hope you do well.
what area is represented by the 8 x 6 model
Answer:
