Answer:

Step-by-step explanation:

log 3y = log(y)^3 (exponent)

or

= log(y)*log(y)*log(y)  (multiples)

The logarithmic expression y = log(3y) can be written as sum or difference of common logarithms as log(3y) = log(3) + log(y).

        [tex]$\log_{b}({b^x})=x[/tex]           {where [b] is logarithmic base}

Given is the following logarithmic expression as -

y = log(3y)

We have the following logarithmic expression -

y = log(3y)

Using the identity of logarithm -

log(AB) = log(A) + log(B)

log(3y) = log(3) + log(y)

Therefore, the logarithmic expression y = log(3y) can be written as sum or difference of common logarithms as log(3y) = log(3) + log(y).

Answer:

The value for x is -2 and the value for y is -10 .

Step-by-step explanation:

Firstly , let's write the equations

solving equation 1 to get the values of x

          or ,    -2x+3=7          

      or,  -2x+3-3 =7-3 (subtracting -3 on both sides )

       or ,  -2x=4

        or,  -2x/2  =   4/2  (dividing  by two on both sides )

         or ,  -x =2

           or  x = -2

now let's substitute the values of x  in the equation 2

           3x+1 =5+y (writing second equation as it is )

           or, 3x+1-1=5+y-1 (subtracting  -1 on both sides )

            or , 3x = 4+y  

              or , 3 × -2 = 4+y  (substituting the values of x from equation 1 )

                or ,  -6  =  4 +y

                   or ,  -6-4 = 4+y-4 ( subtracting -4 on both sides  )

                     or ,    -10 = y

      Therefore the values of x and y is -2 and  -10 respectively .

                Hope it helped you .  If you find the answer useful  please rate brainliest , If not Thanks anyway .

Answer:

B

-15 < 99 and | -9 | < | 15 |

Step-by-step explanation:

Those lines " | " refer to absolute value, meaning it is the distance from 0. You can easily get this just by cutting off a negative sign.

So we do know -9 is greater than -15 obviously, and the absolute value of -9 is 9, because -9 is 9 units from 0.

-15 is 15 units away, so when using absolute value, -15 is greater than -9.

Btw, you can only give one brainliest, you don't get the option to give two on brainly.

Answer:

187.5 pounds

Step-by-step explanation:

Fraction of sand = 2/5

Fraction of clay = 2/5

Fraction of peat = 1/5

Pounds of sand = 75

The total pounds of soil required to make Correct mixture : let that be x

Hence,

Using the sand Fraction and pounds which we know :

2/5 of x = 75

2x / 5 = 75

Cross multiply :

2x = 75 * 5

2x = 375

x = 375 / 2

x = 187.5

Required pond of sand =187.5 pounds

Hi there!

1) Determine the perimeter of the square

We're given that the perimeters of the square and the rectangle are equal. Therefore, after finding the perimeter of the square, we will also know the perimeter of the rectangle.

Find the side length of the square using the area formula:

[tex]A=l^2[/tex] where l is the side length

Plug in the given area 121 in.²

[tex]121=l^2[/tex]

Take the square root of both sides

[tex]\sqrt{121} = \sqrt{l^2} \\11=l[/tex]

Therefore, the side length of the square is 11 inches. Plug this into the perimeter formula:

[tex]P=4l[/tex] where l is the side length

[tex]P=4(11)\\P=44[/tex]

Therefore, the perimeter of the square is 44 inches. The perimeter of the rectangle is also 44 inches.

2) Determine the value of x

Use the formula for the perimeter of a rectangle:

[tex]P=2(l+w)[/tex] where l is the length and w is the width

Plug in 3x and x-2 as the length and width

[tex]P=2(3x+(x-2))\\P=2(3x+x-2)\\P=2(4x-2)[/tex]

Plug in the perimeter 44 in.

[tex]44=2(4x-2)[/tex]

Expand the parentheses

[tex]44=8x-4[/tex]

Add 4 to both sides to isolate 8x

[tex]44+4=8x-4+4\\48=8x[/tex]

Divide both sides by 8 to isolate x

[tex]\frac{48}{8}=\frac{8x}{8} \\6=x[/tex]

Therefore, the value of x is 6.

I hope this helps!

Answer:

$74 492.30

Step-by-step explanation:

P= 50 000

r= 8/100 = 0.08

n= 12

t= 5

P(1 + r/n) ^ (nt)

[tex] = 50000(1 + { \frac{0.08}{12} )}^{(12 \times 5)} [/tex]

=74492.285

Answer:

810 AUD

Step-by-step explanation:

t is time in months: you have to substitute with the number of months given from the question.

C=65t + 30 ==> substitute t with 12 since the question provided you the number of months.

--> C = 65(12) + 30 = 780 + 30 = 810

Answer:

x= 0

Step-by-step explanation:

6x-4=2(3x-2)

or,6x-4=6x-4

or,x=o

There are infinite solution of the expression.

We have to given that,

An expression to solve,

6x - 4 = 2 (3x - 2)

Now, We can simplify as,

6x - 4 = 2 (3x - 2)

Apply distributive property,

6x - 4 = 6x - 4

Combine like terms,

6x - 6x = 4 - 4

0 = 0

Hence, There are infinite solution of the expression.

Step-by-step explanation:

Learning could be explained as a process of acquiring knowledge about a certain subject, trade or other aspects of life. In terms of learning about certain school subjects, a student needs to discover him or herself in other to make acquiring knowledge easy and less tedious for him or her. Now, there are designated tools more than evwr which could aid learning. A very important recommendation which could aid acquiring matematicka knowledge is the use of models to gain an insight to the fundamentals of a mathematical problem and thus seeing how it works. After this one can then break down the mathematical procedure embedded or used it aid the model manually in other to grasp the full concept of the principle.

Answer:

for A

Answer:

16 cans per minute

Step-by-step explanation:

Its simple 80 divided by 5 is 16 so ever minute 16 cans are packed.

The ratio of the cans to minutes is 80 : 5 or 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.

It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign: between the numbers.

A machine can pack 80 cans in 5 minutes.

let's denote the number of cans with X and

Time with T

So we have to find the value of X : T

X = 80 and

T = 5 minutes

X : T = 80 : 5  or

X : T = 16 : 1   (divide by 5 on both sides)

It means the machine can pack 16 cans per minute.

Thus, the ratio of the cans to minutes is 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.

Answer:

53 gallons of fuel

Step-by-step explanation:

Step 1: Set up a fraction given the data (Let "x" represent the distance in miles.)

[tex]\frac{10}{250} = \frac{x}{1325}[/tex]

Step 2: Divide the given values (The given values are 10 over 250. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 0.04 once divided)

[tex]\frac{10}{250}\\\\10 \div 250\\\\= 0.04[/tex]

Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the opposite operation in order to find the answer.)

[tex]1325 \times 0.04\\\\= 53[/tex]

Therefore, 53 is the amount of gallons of fuel needed.
