PLEASE ANSWER ASAP!!!! 3x+x-3/2=0

Mathematics
1 answer:
sesenic [268]3 years ago
4 0

Answer:

x = 3/8 or 0.375

Step-by-step explanation:

For this equation, you need to set it up so it's easier to work with. For example, 3x + x - 3 ÷ 2 = 0. Next, use the order of operations which is the acronym PEMDAS.

P = parentheses (first if there is any)

E = exponents (if there is any)

M/D = Multiply or Divide

A/S = Add or Subtract

Since we have a division problem to do, we need to simplify the division first based on the order of operations.

3x + x <u>- 3 ÷ 2 </u>= 0. -3 ÷ 2 is equal to -1.5. Every division problem is also a fraction. Next, you will have left 3x + x - 1.5 = 0. When you have both subtraction and addition in the equation, all you have to do is solve from left to right. There is an addition problem to solve first then the subtraction problem. For example: <u>3x + x</u> - 1.5 = 0, which equals to 4x - 1.5 = 0. Next, you add 1.5 to -1.5 and 0. Anything added or subtracted by a number and it's opposite will always equal 0. For example: 4x <u>- 1.5 + 1.5</u> =<u> 0 + 1.5. </u> You have to get rid of the -1.5 and 1.5 since it equals 0. This will be left with 4x = 1.5. Divide both sides by 4 to balance the equation. For example: <u>4x ÷ 4 = 1.5 ÷ 4. </u>Do you see that the 4's on one side cancel each other out? You are left with x = 3/8.

Problem 4:
Kipish [7]

Answer:

12cm and 16cm

Step-by-step explanation:

The hypotenuse of the right angle triangle  = 20cm

 let the other two sides be x and y;

 The difference;

                x  = y - 4

Problem:

Find x and y;

Solution:

According to the pythagoras theorem;

    x² + y² = 20²  ------ i

       x² + y² = 400 ----- i

and  x - y = 4 ---- ii

So;   x = 4 + y

Now input the value into equation (i);

  (y + 4)² + y² = 400

   (y+4)(y+4) + y² = 400

    y² + y² + 4y + 4y + 16 = 400

    2y² + 8y + 16 = 400

    2y² + 8y + 16 -400 = 0

   2y² + 8y - 384 = 0;

      y² + 4y - 192 = 0

Factorize the equation;

  y² + 16y - 12y - 192 = 0

  y(y + 16) - 12(y + 16) = 0

  (y-12)(y + 16) = 0

     y -12 = 0 or y+ 16 = 0

     y = 12 or -16

It is not realistic for the length of a body to be a negative value, so y= 12;

   since;

    x - y = 4,

    x = 4 + 12

    x = 16

How to state gradient and y-intercept
n200080 [17]

In summary. The graph of each equation is a straight line, m is the gradient of the line and c is the y-intercept. Conversely, if a straight line has gradient m and y-intercept c it has equation y = mx + c.
