Solve the equation for x, where x is a real number:
-2x^2 + 7x - 5 = 0

Answers

First you must know this.
{ax}^(2)  + bx + c = 0
Then, you will know that a=-2 b=7 c=-5.
Now, use the quadratic formula.
x = \frac{ \: - b +  -  \sqrt{ {b}^(2)  - 4ac } }{2a}
x =  \frac{ \: - 7  +  - \sqrt{ {7}^(2)  - 4( - 2)( - 5) } }{2 *  - 2}
You will then get two values for x.
x = 1 \: and \: x = 2.5
there you go! That's the answer.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                      x = [ -b ± √(b^2 - 4ac) ] / (2a)
                      x = [ -7 ± √((7)^2 - 4(-2)(-5)) ] / ( 2(-2) )
                      x = [-7 ± √(49 - (40) ) ] / ( -4 )
                      x = [-7 ± √(9) ] / ( -4)
                      x = [-7 ± 3 ] / ( -4 )
                      x = 7/4 ± -3/4
The answers are 7/4 + 3/4 = 5/2 and 1.

Translate the word phrase into an algebraic expression: sixteen times the sum of 10p and seventeen

Answers

The word phrase "sixteen times the sum of 10p and seventeen" can be translated into the following algebraic expression 16(10p + 17)

The word "sum" means that we add 10p and 17. The word "times" means that we multiply the sum by 16.

Therefore, the algebraic expression 16(10p + 17) represents the phrase "sixteen times the sum of 10p and seventeen".

Here is a step-by-step translation:

Break the phrase "sixteen times the sum of 10p and seventeen" into smaller parts.

Translate each part into an algebraic expression.

Combine the algebraic expressions into a single expression.

The translated expression is 16(10p + 17).

12% of students of a class of 50 like blue
colour. How many children like blue colour?​

Answers

If 12% of students of a class of 50 like blue  colour, the number of children that like blue is 6

The number of students in the class = 50

12% of the total number of students like blue

Number of students that like blue colour = 12% of 50

Number of students that like blue colour = (12/100)  x  50

Number of students that like blue colour = 0.12  x  50

Number of students that like blue colour = 6

Therefore, if 12% of students of a class of 50 like blue  colour, the number of children that like blue is 6

You have a litre bottle of water and drink 375 millilitres.

How much is left?

Answers

The balance of water left in the bottle is 625 milliliters.

How Liters and Milliliters are calculated?

  • A liter exists as a unit of volume in the metric system.
  • A liter exists described as the volume of a cube that exists 10 centimeters on a side.
  • Liters and milliliters are metric units of volume which are used to measure the capacity of a liquid.
  • The capacity of a liquid can be measured in milliliters, centiliters, liters, and kiloliters.
  • There are about 3.785 liters in a U.S. gallon.

1 liter = 1000 milliliters

Let, 1000 milliliters - 375 milliliters = 625 milliliters
