Is 1709 divisible by 2,3,5,6,9
coldgirl [10]
Hey mate!
Let's figure this out!

The answer is false.

1709 / 2 = 854.5
1709 / 3 = 569.6
1709 / 5 = 341.8
1709 / 6 = 184.8
1709 / 9 = 189.8


Hope this helps! :)

What is the answer of this problem -7/3(3x-2)=-21 ?
weeeeeb [17]

Answer:

= 11/3

Step-by-step explanation:

1. COMBINE MULTIPLIED TERMS INTO A SINGLE FRACTION

- 7/3 (3x-2)= -21

-7 (3x-2) = -21

-----------------------

3

2. DISTRIBUTE

-7( 3x- 2) ➗ 3 =-21

3. MULTIPLY ALL TERMS BY THE SAME VALUE TO ELIMINATE FRACTION DENOMINATORS

-21x + 14 ➗ 3 = 3 (-21)

4. CANCEL MULTIPLIED TERMS THAT ARE IN THE DENOMINATOR

3 ( -21x + 14) ➗ 3 (-21)

5. MULIPLY THE NUMBERS

-21x + 14 = 3(-21)

6. SUBTRACT 14 FROM BOTH SIDES OF THE EQUATION

-21x + 14 = -63

7. SIMPLIFY

-21x = - 77

8. DIVIDE BOTH SIDES OF THE EQUATION BY THE SAME TERM

-21x/-21 = -77/-21

9. SIMPLIFY

x = 11/3

Last math question.

Answer:

<h2>y = 5x + 11</h2>

Step-by-step explanation:

\text{The slope-intercept form of an equation of a line:}\\\\y=mx+b\\\\m-\text{slope}\\b-\text{y-intercept}\\\\\text{Let}\\\\k:y=m_1x+b_1\\l:y=m_2x+b_2\\\\k\ \perp\ l\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\k\ ||\ l\iff m_1=m_2\\=========================

\text{We have}\ y=5x+2\to m_1=5\\\\\text{therefore}\ m_2=5.\\\\\text{Put the value of the slope and the coordinates of the given point (-2, 1)}\\\text{to the equation of a line:}\\\\1=5(-2)+b\\1=-10+b\qquad\text{add 10 to both sides}\\1+10=-10+10+b\\11=b\to b=11\\\\\text{Finally:}\\\\y=5x+11

Please help me with this I’ll make you as brainlist
Arlecino [84]

Answer:

x = 3\sqrt{13} = 10.8

Step-by-step explanation:

Both problems are done the same way.  I will do the first one and you do the second one.  OK?

Move the radius x to make a right triangle.  The 6 unit segment bisects the chord.  So, the legs of the right triangle are 6 and 9

The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle.   Now,

6^{2}  + 9^{2}  = x^{2}

x^{2} = 36 + 81 = 117\\x = \sqrt{117} = 3\sqrt{13}= 10.8

None of the answer choices are to the nearest tenth.  So, I am confused about that.

In  the second problem, the answer should be 11.2

Answer for brainlest for 25 points
Gnom [1K]

Answer:

1. 23/4  ,  2. 5.555...   , 3. 5 1/2   ,    4. √28

you want to make them all into decimals so you can compare then easier

23/4 would be 5.75

√28 (just put it in a calculator)  would be 5.29

5 1/2  would be 5.5  (make  it into a improper fraction 11/2 then do 11/2 and you get 5.5)

and you have 5.555.

so...

5.75

5.29

5.5

5.55555

first is 5.75 it's bigger because of the .(75)

then 5.555 because it's .(55)

then 5.5 because it's .(50)

and the last one 5.(29)
