Factorise fully <br> -x-5
liraira [26]

The fully factorized version of  -x-5 is -1 \times (x+5).

What is Factorization?

Usually, factorization or factoring means writing a number (or another mathematical object) as a product of minor or more uncomplicated objects of the same kind.

Given -x-5 is a linear expression.

For factorizing, first, make the coefficient of x positive. For this take -1 common.

⇒ -x-5 = -1\times(x+5)

Now take the greatest common divisor (gcd) of absolute values of coefficients in x+5.

⇒ gcd(1,5) = 1.

Now take gcd 1 common in the expression.

⇒ -1\times1\times(x+5)

⇒ -1\times(x+5).

∴ The fully factorized version of -x-5 is -1\times(x+5).

PLEASE HELP <br> URGENT!!!!!!!!!!!!!!!
trasher [3.6K]

Answer:

a.) 26< a <u>28 </u>  

b.) 4

Step-by-step explanation:

a.) After looking at the age in years collum you can notice that all of ages have a difference of 2. With this you can infer that the missing number is 28.

b.) To find the mean add up all the numbers in the frequency column.

3+2+7+8+0=20

Divide that by the amount of numbers. There are 5 numbers so 20/5=4.

Hope this helps!

The ratio of a model building's dimensions to the building's actual dimensions is 1/52. If the height of the model is 15 inches,
g100num [7]
Set this up as a proportion with the model stuff on top and actual building stuff on bottom.  \frac{1}{52} = \frac{15}{x}.  Cross multiply to get x = 780.  The actual building is 780 inches.  In feet that is 65.

How many gallons each of 20​% alcohol and 10​% alcohol should be mixed to obtain 10gal of 11​% ​alcohol?
Scilla [17]

Answer:

20​% alcohol = 1 gal

10​% alcohol = 9 gal

Step-by-step explanation:

Let

x = 20​% alcohol

y = 10​% alcohol

x + y = 10 (1)

0.20x + 0.10y = 10*0.11

0.20x + 0.10y = 1.1 (2)

From (1)

x = 10 - y

Substitute x = 10 - y into (2)

0.20x + 0.10y = 1.1

0.20(10 - y) + 0.10y = 1.1

2 - 0.20y + 0.10y = 1.1

- 0.20y + 0.10y = 1.1 - 2

-0.10y = -0.9

y = -0.9/-0.10

y = 9 gal

substitute y = 9 into (1)

x + y = 10

x + 9 = 10

x = 10 - 9

x = 1 gal

20​% alcohol = 1 gal

10​% alcohol = 9 gal
