Mathematics
1 answer:

8 0

Answer:

-3x^2-4x

Step-by-step explanation:

Simplify:

\left(2x-7\right)-\left(4x^2+6x-3\right)+\left(x^2+4\right)

=2x-7-\left(4x^2+6x-3\right)+x^2+4

Group same factor:

=-\left(4x^2+6x-3\right)+x^2+2x-7+4

Add :

=-\left(4x^2+6x-3\right)+x^2+2x-3

Apply the distributive law: -(a+b) = -a - b

-\left(4x^2+6x-3\right)=-4x^2-6x+3

=-4x^2-6x+3+x^2+2x-3

Group same factor:

=-4x^2+x^2-6x+2x+3-3

Subtract:

=-4x^2+x^2-6x+2x

Add:

=-3x^2-6x+2x

Group same factor:

=-3x^2-4x

Hence answer = -3x^2-4x

Answer:

50

Step-by-step explanation:

Using the experimental probability, first we have to find total amount paint then to find the amount of good quality forever paint we have to subtract the amounts of other paints from total amount.

Let x represents the amount of good quality forever paint sold.

Total amount of paint =48+45+35+39+33+x=200+x     ...(i)

Experimental probability of paint sold will be better quality durable paint is

P=\dfrac{\text{Amount of better quality durable paint}}{\text{Amount of total paint}}

P=\dfrac{45}{\text{Amount of total paint}}

It is given that experimental probability of paint sold will be better quality durable paint is \frac{9}{50}.

\frac{9}{50}=\dfrac{45}{\text{Amount of total paint}}

\text{Amount of total paint}=\dfrac{45\times 50}{9}

\text{Amount of total paint}=250     ...(ii)

From (i) and (ii), we get

200+x=250

x=250-200

x=50

Therefore, 50 gallons good quality forever paint is sold.

When solving negative one over five (x − 25) = 7, what is the correct sequence of operations?
Stels [109]

Answer:

Multiply each side by −5, add 25 to each side

Step-by-step explanation:

-1/5(x-25) = 7

Multiply each side by -5/1 to clear the fraction

-5/1* -1/5(x-25) = 7*-5/1

x-25 = -35

Then add 25 to each side

x-25+25 = -35+25

x = -10
