3/2=4/3x+2/3 What does X equal?
Anna71 [15]

Answer:

x = 30/48 or x = 0.625

Step-by-step explanation:

3/2 = 4/3x + 2/3

Convert to common denominator

9/6 = 8/6x + 4/6

subtract 4/6 from both sides

9/6 - 4/6 = 8/6x + 4/6 - 4/6

5/6 = 8/6x

Divide by 8/6

5/6 x 6/8 = x

30/48 = x

x = 30/48

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Find the value of x. Round to the<br> nearest tenth.<br> 15.6 cm<br> 8.8 cm<br> x = [ ? ]cm
kenny6666 [7]

Answer:

x = 4.1 cm

Step-by-step explanation:

To find x, apply pythagorean theorem, which is given as:

c² = b² + a²

Where,

c = 8.8 cm

b = ½(15.6) = 7.8 cm

a = x

Plug in the values

8.8² = 7.8² + x²

77.44 = 60.84 + x²

Subtract both sides by 60.84

77.44 - 60.84 = x²

16.6 = x²

Take the square root of both sides

√16.6 = x

x = 4.07430976

x = 4.1 cm (nearest tenth)

Which equation represents the line passing through the points (3, 2) and (-9, 6)?
Sliva [168]

Answer:

Step-by-step explanation:

The equation of a linear function in point-slope form is y – y1 = m(x – x1)

The point is A (x1 , y1)

in this exercice : x1 = 3  and  y1 =2

let  A(3,2)    B(-9,6)

the slope is : m =   (YB - YA)/(XB -XA)

(6-2)/(-9-3)  =4/(-12)  = -1/3

the slope is   m = -1/3

The equation is :  y – y1 = m(x – x1)

y-2 =-1/3 ( x-3)

or : 3y-6 = -x+3
