What is the value of the expression

Evaluating an expression is the process of finding its value by replacing the variables in the expression with their respective values and applying the rules of arithmetic. For example, given the expression "2 + 3", evaluating it would result in the value "5".

There are many types of expressions, including arithmetic expressions, which involve numbers and mathematical operators such as +, -, *, and /. There are also expressions involving variables, where the value of the expression depends on the value assigned to the variables.

In the given problem, the expression is;

(1/4)⁻² - [5⁰ * 2] * 1⁻¹

Applying mathematical operators through PEDMAS;

16 - [1 * 2] * 1 = 14

A stunt person opens his parachute at a height of 505 feet above the ground. He then descends at a constant rate.

Let y represent his height above the ground in feet. Let x represent the time, in seconds, he spent descending with his parachute open. Which equation is represented by the graph?

Question 2 options:

y = 505x + 17

y = 17x + 505

y = –17x + 505

y = 17x – 505

Answers

Answer:

It's -17x + 505

Step-by-step explanation:

The linear equation is like y=mx+b

Solve it by using linear equation knowledge: because the graph is going down, or the height is descending, so the the slope must be negative.

And the choise of slope is 505, 17, -17, 17, so the one with negative: -17 slope is correct.

Answer:

17x + 505

y=MX+b

Solve it by using a linear equation, the graph is going down the slope must be negative

-17 slope is The Right answer for you.

At an office supply store, Samantha bought 5 notebooks and 2 pens for $9.
Jeffrey bought 3 notebooks and 2 pens for $6. Write a system of equations to represent this situation.

Answers

Answer: Let x be the cost of one notebook and y be the cost of one pen. Then we can write the following system of equations to represent the situation:

5x + 2y = 9

3x + 2y = 6

This system represents the fact that Samantha paid $9 for 5 notebooks and 2 pens, and Jeffrey paid $6 for 3 notebooks and 2 pens.

Step-by-step explanation:

Answer: hope this helps ♡

5x + 2x = 9

3x + 2x = 6

Step-by-step explanation:

x = cost of 1 item

Samantha → 5x + 2x = $9

Jeffrey → 3x + 2x = $6

5x + 2x = 9

Answer: Company B charges $0.08x + $30.00 more than Company A for x miles.

Step-by-step explanation:

The total cost for Company A for x miles is 0.09x + 30.50, and the total cost for Company B is 0.17x + 60.50. To find how much more Company B charges than Company A for x miles, we can subtract the cost of Company A from the cost of Company B:

(0.17x + 60.50) - (0.09x + 30.50)

Simplifying the expression, we get:

0.08x + 30.00

Therefore, Company B charges $0.08x + $30.00 more than Company A for x miles.

Company B charges $0.08 x + $30.00 more

You are looking for the price of 4 pairs of shoes after 20 days of being on sale. You have $100 and you have to find out whether you can buy these shoes.

How to solve:

After 20 days 1 pair of shoes will cost:

$40/1 x 2/5 = 16$

40-16 = 24

So 1 pair of shoes will cost $24 after 20 days.

24x4 = $96

4 pairs of shoes after 20 days cost $96. We have 100$, So we will be able to purchase it.

3(12X+7)

Answers

Whatever is outside the parentheses is what you are distributing to what’s inside.

So with 3, you would multiply it by 12X. You would get 36X.

Now you do the same thing. 3 times 7 is 21.

Your distributed answer is:

36X+21

Multiple 3 times 12x and you will get 36x and then multiply 3 times 7 and you will get 21

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?

Answers

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400

Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
= 1710 fish

Hope you understood the answer and I hope it helps you :)
