What is the multiplication inverse of 1/2

Mathematics
1 answer:
vitfil [10]3 years ago
8 0

Answer:

multiplicative inverse of 1/2 is 2

Step-by-step explanation:

The multiplicative inverse of a/b is b/a

Because \frac{a}{b} * \frac{b}{a} =1

To get multiplicative inverse of any fraction we take the reciprocal of that fraction

Multiplicative inverse of  \frac{1}{2} \ is \ \frac{2}{1}

2/1 or 2  are same

so multiplicative inverse of 1/2 is 2

The diagonals of rhombus fghj intersect at point k. if side gh is equal to 3x - 10 and side jh is equal to 6x - 19, find x
exis [7]
A rhombus is a square but turned so it looks like a diamond. This means all the sides are equal. With this information we can build an equation to solve for x.

3x - 10 = 6x - 19

1) Subtract 3x from both sides.

-10 = 3x - 19

2) Add 19 to both sides.

9 = 3x

3) Divide both sides by 3.

3 = x

x =3.

What is the solution of the inequality [3x+6]-2&lt;10?
Ber [7]

Answer:

x > -3_2/3

Step-by-step explanation:

(3x+6)-2 < 10

Distribute  

-6x-12 < 10

    +12   +12

    -6x < 22

-6x/-6 < 22/-6

When you divide by a negative number you flip the inequality

x > 22/-6

Simplify

x > -3_2/3

<h3 />

<h3><u>To find value of z:</u></h3>

<u>Formula applied:</u>

Exterior angle=Sum of interior angles

Answer:

  • 119⁰=43⁰+z⁰

  • 119⁰-43⁰=z⁰

  • z⁰=<u>76</u><u>⁰</u><u>✔</u>

<h3><u>To find value of y:</u></h3>

  • ∠1+66⁰=180⁰(L.P)
