Which equation can be used to represent the statement? Sixteen is the same as one and two-tenths times a number added to negativ
andreyandreev [35.5K]

The equation can be used to represent statement 'Sixteen is the same as one and two-tenths times a number added to negative 8' is,

16=1.2n+(-8)

<h3>How to write algebraic equation from statement? </h3>

Algebraic equation are the expression which consist the variables, coefficients of variables and constants.

The algebraic equation are used represent the general problem in the mathematical way to solve them.

Steps to write down the simple algebraic equation from statement-

  • Identify all the factors of the expression.
  • Assume a variable for the changing values.
  • Put a coefficient for the variable, if there is any rate of change of variable.
  • Use constant numbers for the fixed values.

Given information-

The given statement is  'sixteen is the same as one and two-tenths times a number added to negative 8'.

The statement given in the problem is talking about a unknown number. Let the unknown number is n.

The number is sixteen is the same as one and two-tenths times a number added to negative 8.

This means when our number n, multiplied by the fraction 2/10, and added by the negative 8, then it becomes equal to the number 16. Mathematically,

16=n+\dfrac{2}{10}\times n+(-8)\\16=1.2n+(-8)

Thus the equation can be used to represent the given statement is,

16=1.2n+(-8)

In a sale, normal prices are reduced<br> by 25%.<br> The sale price of a calculator is<br> £8.82
Lelu [443]

Answer:

2.2050

Step-by-step explanation:

25% -> 2500.

25% is just a way of saying 25 out of 100. So we have to times 25 by 100 which gets you 2500. You the have to multiply 2500 by 8.82 which will get you 22050. Now the price is reduced by 25% so the answer will be less than 8. You have to add a decimal somewhere in the number 22050 and it has to be less than 8. You could but it after the second 2 but then it will be over 8. So the only spot you can put it is after the first 2 like this 2. so the answer will be 2.2050

Sam drove 320 miles in 2.5 hours, how long will it take to drive 500 at the same rate (speed)?
frosja888 [35]

Answer:

<u>Sam would take to drive 500 miles in 4 hours and 34 minutes at the same speed.</u>

Step-by-step explanation:

It is easy to say that if Sam continues driving at the same speed it will take a little longer to drive the 500 miles.

If Sam drives 320 miles in 150 minutes (2.5 hours)

How long will it take to drive 500 miles at the same speed?

An equation called "rule of 3" can be applied:

320 miles = 150 minutes

500 miles = X?

X is cleared from the equation

X = (500 miles * 150 minutes) / 320 miles

X = 234.37 minutes

Now we spend 234.37 minutes at hours with the same rule of 3

1 hour = 60 minutes

 X = 234.37 minutes

Clearing X would give

X = (1 hour * 234.37 minutes) / 60 minutes

X = 4 hours and 34 minutes

Sam would take 500 miles in 4 hours and 34 minutes
