Answer:

a) The equation for the situation = 14.50 = 4.5 + 1.25n

b) The number of oranges she bought = 8 oranges

Step-by-step explanation:

Where n represents the number of oranges.

The equation is written as

Total charge = $0.75 × 6 + $1.25 × n

$14.50 = $0.75 × 6 + $1.25 × n

14.50 = 4.5 + 1.25n

1.25n = 14.5 - 4.5

1.25n = 10

n = 10 / 1.25

n = 8 oranges

If one side of a rectangle is five less than the other side and the perimeter is 90 inches, find the area of the rectangle.
horsena [70]
So given a rectangle
sides are 
     _<u>x</u>_
x-5|__|x-5
      x

the perimeter is 90 inches
perimeter is 
x + x + (x-5) + (x-5) = 90
combine like terms
2x + 2(x-5) = 90
distribute
2x + 2x-10 = 90
combine like terms
4x - 10 = 90
add 10 to both sides
4x= 100
divide both sides by 4
x = 25

now to find the length of a side 
x is 25
and x-5 is 20

to check and see if that's right:
25 + 25 + 20 + 20 =?= 90 
50 + 40 =?=
90 = 90

Now to find the area
A = b * h
so
x * (x-5)
substitute
25* 20
500
The area of the rectangle is 500

Hope this helps :)

In class of 25 students 3 students failed. what is the probability that student from this class will pass (not fail)
elixir [45]
The probability that a student will fail is 3/25, there are 25 of them, thus the sample space is 25 and 3 out of that is 3/25 or 0.12.

what's the probability that one will pass?  well, the opposite of failing, thus is the complement of 0.12, namely, 1 - 0.12.

Can somebody help me with all three problems please
Lerok [7]

1. x^{2} -10x +25 = 0

These two numbers are: -5 and -5

-5 + (-5) = -10

-5 * -5 = 25

so...

(x - 5)(x - 5)

To find the roots set the factored numbers equal to zero and solve for x:

x - 5 = 0

x = 5

2. x^{2} + 9x = -14

This equation needs to be equal to zero, so bring -14 to the other side by adding 14 to both sides

x^{2}+9x+14 =0

Find two numbers that the sum is equal to 9 AND the multiplication of the numbers is 14

These numbers are 7 and 2

7 + 2 = 9

7*2 = 14

so...

(x + 2) (x + 7)

To find the roots set the each of the factored numbers equal to zero and solve for x:

x + 2 = 0

x = -2

x + 7 = 0

x = -7

3. 3x^{2} = 6x

This equation needs to be equal to zero, so bring 6x to the other side by subtracting 6x to both sides

3x^{2} -6x = 0

In this equation you can factor out a 3 and an x:

3x (x - 2)

To find the roots set the each of the factored numbers equal to zero and solve for x:

3x = 0

3x/3 = 0/3

x = 0

x - 2 = 0

x = 2

Hope this helped!
