Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{x = 30}}}}}

Step-by-step explanation:

\sf{1200 - 5(3x + 30) = 600}

Distribute 5 through the parentheses

\dashrightarrow{ \sf{1200 - 15x - 150 = 600}}

Subtract the numbers: 150 from 1200

\dashrightarrow{ \sf{ - 15x  + 1050 = 600}}

Move 1050 to right hand side and change it's sign

\dashrightarrow{ \sf{ - 15x = 600 - 1050}}

Subtract 1050 from 600

\dashrightarrow{ \sf{ - 15x = 450}}

Divide both sides of the equation by -15

\dashrightarrow{ \sf{ \frac{ - 15x}{ - 15}  =  \frac{ - 450}{ - 15} }}

Calculate

\dashrightarrow{ \sf{x = 30}}

Hope I helped!

Best regards! :D

Answer:

x=+30

Step-by-step explanation:

1200-5(3x+30)=600

We move all terms to the left:

1200-5(3x+30)-(600)=0

We add all the numbers together, and all the variables

-5(3x+30)+600=0

We multiply parentheses

-15x-150+600=0

We add all the numbers together, and all the variables

-15x+450=0

We move all terms containing x to the left, all other terms to the right

-15x=-450

x=-450/-15

x=+30

I need to help my child do division but I don't know how to do it myself
Sedaia [141]
Well this is a hard question to answer, but this is how i would put it.

 You would take a number (lets use 15) and the second number (lets use 5) would determine how many times it would go into 15. In other words, 5 time x would equal 15 (5x=15). 5, being a factor of 15, would evenly fit into 15 three times.

Answer:

7.235 cm

Step-by-step explanation:

Pythagorean theory

A^2 + B^2 = C^2

A = 4.7

B = 5.5

4.7^2 + 5.5^2 = C^2

22.09 + 30.25 = C^2

√52.34 = √C^2

7.235 cm ≈ C

Evaluate the square root
Alexandra [31]

\sqrt{a}=b\iff b^2=a\ for\ a\geq0\ and\ b\geq0\\\\\sqrt{\dfrac{1}{144}}=\dfrac{\sqrt1}{\sqrt{144}}=\dfrac{1}{12}\\\\\\\sqrt1=1\ because\ 1^2=1\\\\\sqrt{144}=12\ because\ 12^2=144
