3 our of 5 in two equivalent forms
sammy [17]
Hello!

3 out of 5 looks like this as a fraction:

3/5

We cannot divide this further as both the numerator and the denominator are odd numbers, so we must multiply to get an equivalent fraction:

3/5 = 6/10 = 60/100

3/5 is also equivalent to 0.2 as a decimal or 20% as a percentage.

-12 -4x + 3 = -1 what is the value of x
Vinil7 [7]

Answer:

Its -2

Step-by-step explanation:

Let's solve your equation step-by-step.

−12−4x+3=−1

Step 1: Simplify both sides of the equation.

−12−4x+3=−1

−12+−4x+3=−1

(−4x)+(−12+3)=−1(Combine Like Terms)

−4x+−9=−1

−4x−9=−1

Step 2: Add 9 to both sides.

−4x−9+9=−1+9

−4x=8

Step 3: Divide both sides by -4.

−4x

−4

=

8

−4

x=−2

Find the other x-intercept for the parabola defined by this equation y=2x2+3-2​
ASHA 777 [7]

Answer:

( \frac{1}{2}, 0 )

Step-by-step explanation:

To find the x- intercepts let y = 0, that is

2x² + 3x - 2 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 2 = - 4 and sum = + 3

The factors are + 4 and - 1

Use these factors to split the x- term

2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )

2x(x + 2) - 1 (x + 2) ← factor out (x + 2) from each term

(x + 2)(2x - 1) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = \frac{1}{2}

The x- intercepts are (- 2, 0 ), ( \frac{1}{2}, 0 )
