Answer:

5.) b

6.)a

Step-by-step explanation:

5.) b

3x - 24 = 81 (add 24 on both sides)

3x = 105 (divide by 3 on both sides)

x = 35 or 105/3

6.) a

-5x - 25 = 78 (1st add 25 on both sides)

-5x = 103 (2nd divide both sides by -5)

x = -20.6

Hope this helps ya!!

A circular field has arey 144001 square feet.<br> What is the radius of the field?
anzhelika [568]

Answer:

about 214.1

Step-by-step explanation:

Since pi r squared is the formula for a circle's area, you would do the opposite. First, you would divide 144001 by pi which is about 45,836.94. Then, you would find the square root of that which is about 214.1.

What additional information is required in order to know what triangles are congruent
aev [14]

Answer:

C. RS=IS

Step-by-step explanation:

To use ASA the side between the two congruent angles must be equal as well. Given one set of congruent angles, we can assume the other congruent angles to be the vertical angles in the middle.  In order for ASA to work, the side between those angles must also be congruent.

After making a Deposit puja had $264 in her savings account she noticed that if she added $26 to mount originally in the account
ki77a [65]

Answer:

She had $106.

Step-by-step explanation:

2(x+26)=264

Step 1: Simplify both sides of the equation.

2(x+26)=264

(2)(x)+(2)(26)=264(Distribute)

2x+52=264

Step 2: Subtract 52 from both sides.

2x+52−52=264−52

2x=212

Step 3: Divide both sides by 2.

2x/2=212/2

x=106

Determine the intercepts of the line that correspond to the following table of values. x y 4 0 12 5 20 10
gogolik [260]

Let

A(4,0)

B(12,5)

C(20,10)

we know that

The x-intercept of the line is the value of x when the value of y is equal to zero

The y-intercept of the line is the value of y when the value of x is equal to zero

The point A(4,0) is the x-intercept of the line

<u>Find the slope AB</u>

m=(y2-y1)/(x2-x1)

mAB=(5-0)/(12-4)--------> mAB=5/8

<u>with the slope m and the point A(4,0) find the equation of the line</u>

y-y1=m*(x-x1)----------> y-0=(5/8)*(x-4)-------> y=(5/8)x-2.5-----> y=0.625x-2.5

<u>Find the y-intercept</u>

For x=0

y=0.625*0-2.5---------> y=-2.5

the y-intercept is the point (0,-2.5)

therefore

<u>the answer is</u>

the x-intercept is the point (4,0)

the y-intercept is the point (0,-2.5)

see the attached figure to better understand the problem
