927 is your answer 10.3*90 use a calculator brainliest answer me

Well, then I'm guessing you're only feeding 90 of them since 10 of the dogs are sleeping. If so, then set up a proportion:

\frac{number of dogs}{amount of food}

\frac{100}{10.3}

A proportion is a two fractions set equal to eachother. So, the second fraction will be the number of dogs over x. X will be the amount of food the dogs will get.

\frac{90}{x}

Set the two equations equal to eachother

\frac{100}{10.3} =  \frac{90}{x}

To solve a proportion, cross multiply

100 x X = 100x

90 x 10.3 = 927

100x = 927

Divide 100

x = 9.27

So, the dogs will receive 9.27 of food

What is the discriminant of the quadratic equation 0 = 2x2 3x – 5?
a_sh-v [17]
If you would like to find the discriminant of the quadratic equation 0 = 2x^2 + 3x - 5, you can do this using the following steps:

<span>0 = 2x^2 + 3x - 5
0 = ax^2 + bx + c
a = 2, b = 3, c = - 5

</span>D = b^2 - 4 * a * c = 3^2 - 4 * 2 * (-5) = 9 + 40 = 49

The correct result would be 49.

1/4x +4 = 1/2 solve with explanation
IRINA_888 [86]

Answer:

<h3>x = -14</h3>

Step-by-step explanation:

Given the equation

1/4x +4 = 1/2

Solving for x

Subtract 4 from both sides

1/4x +4 - 4 = 1/2 - 4

1/4 x  = (1-8)/2

1/4 x = -7/2

Cross multiply

2x = -7*4

2x = -28

x = -28/2

x = -14

Hence the value of x is -14

Solve for x.
olga nikolaevna [1]

Answer:

\boxed{x=5},x=-9

Step-by-step explanation:

To rid the denominators, multiply both sides by (x-3)(x+1).

We get:

6(x+1)-12(x-3)=(x-3)(x+1)

Simplifying, we have:

6x+6-12x+36=x^2-3x+x-3,\\-6x+42=x^2-2x-3,\\x^2+4x-45=0

Solving, we get:

x^2+4x-45=0,\\(x-5)(x+9)=0,\\x=5,x=-9

Therefore, the solution with the greatest value is x=\boxed{5}
