Okay ...
you do the opposite
 
so you do

38-15=23

that would leave you with
7x=23
you then get x on its own by dividing 7x by 7
 
and because you divided one side yo must divide the other ..
so
23/7 =
3.2857
x=3.3

Square root of 648.7209 by division method
SpyIntel [72]

Answer:

25.47

Step-by-step explanation:

This root can be rewritten as:

\sqrt{\frac{6487209}{10000} }

\sqrt{\frac{6487209}{100^{2}} }

\frac{1}{100}\cdot \sqrt{6487209}

Since 6487209 is a multple of 3, the expression can be rearranged as follows:

\frac{1}{100}\cdot \sqrt{3\times 2162403}

2162403 is also a multiple of 3, then:

\frac{1}{100}\cdot \sqrt{3^{2}\times 720801}

\frac{3}{100}\cdot \sqrt{720801}

720801 is a multiple of 3, then:

\frac{3}{100}\cdot \sqrt{3\times 240267}

240267 is a multiple of 3, then:

\frac{3}{100}\times \sqrt{3^{2}\times 80089}

\frac{9}{100}\cdot \sqrt{80089}

80089 is a multiple of 283, then:

\frac{9}{100}\cdot \sqrt{283^{2}}

\frac{9\times 283}{100}

\frac{2547}{100}

Please help just looking for the answer
avanturin [10]

Answer: Correct Answer is 4th option , 28


Step-by-step explanation:


We can find the measure of the angle using the tangent.


We know, tangent of an angle = Perpendicular/Base, corresponding to that angle.


So, Tan of angle T = RG / RT

or, Tan of angle T = 8/15

or, angle T = tan inverese of 8/15

or, angle T = 28.07


So, angle T rounded to nearest degree = 28


Hope this helps.


Thank you.

Which expression shows a sum of three terms.
vladimir1956 [14]

Answer:  B) 3+y+3

This can be simplified to y+6, but the current un-simplified expression has 3 terms.

======================================

Explanation:

Terms are separated by a plus sign. If you had something like 10x-5y, then you would write that as 10x+(-5y) showing that 10x and -5y are the two terms.

Choices A and C, xy and 6y respectively, have one term each. They are considered monomials. Mono = one, nomial = name.

Choice D is the product of the constant 3 and the binomial y+3. Binomials have two terms.

Only choice B has three terms, though we can simplify it down to two terms. I have a feeling your teacher doesn't want you to simplify it.
