Answer:

- 120x + 288y

Step-by-step explanation:

Begin by summing the 2 expressions

- 2(10x + 3y) - 5(6y - 7x) ← distribute parenthesis

= - 20x - 6y - 30y + 35x ← collect like terms

= 15x - 36y

Now multiply the result by - 8

- 8(15x - 36y) ← distribute

= - 120x + 288y

Answer:

Step-by-step explanation:

-2(10x + 3y)

-20x -6y         [-2 multiplied by 10x = 20x,      negative + positive = negative]

-5(6y -7x)

-30y + 35x

-20x -6y -30y +35x

35x - 20x     -30y -6y

          <em><u>15x - 36y</u></em>

<em><u /></em>

<em><u>Answer = 15x -36y</u></em>

Can you please help me with solving this math problem. 1/4 (x+2)=5/6
Verdich [7]

So firstly, multiply both sides by 4 (the reciprocal of 1/4): x+2=\frac{20}{6}=3\frac{2}{6}

Next, subtract both sides by 2 and your answer will be: x=1\frac{2}{6}

4log x-1/2log y+3log z
babymother [125]
Following rules of logs, we can do the following:

log x^4 - log y^(1/2) + log z^3

Combine the first and 3rd factors to get    log [x^4*z^3]

Seeing that the neg. sign signifies division, write this new term - log y^(1/2) as a quotient:

        [x^4*z^3]
log ----------------
           y^(1/2)

Next time, please include the instructions when you present your problem.
Thx.

If tan x =3/4, and 0
jasenka [17]

Answer: x=0.6435011

Step-by-step explanation:

Take the inverse tangent of both sides of the equation to extract  

x

from inside the tangent.

x

=

arctan

(

3

4

)

Evaluate  

arctan

(

3

4

)

.

x

=

0.6435011

The tangent function is positive in the first and third quadrants. To find the second solution, add the reference angle from  

π

to find the solution in the fourth quadrant.

x

=

(

3.14159265

)

+

0.6435011
