Select the equation in which you use the inverse property of multiplication to find the solution.

loris [4]

Given:

Equations using properties.

To find:

The equation which use the inverse property of multiplication.

Solution:

Inverse property of multiplication:

The product of any number and its reciprocal is always 1.

Let us select the option which uses inverse property of multiplication.

Option A: $\left(\frac{3}{4} \cdot \frac{4}{3}\right)+7=8$

Inverse of $\frac{3}{4}$ is $\frac{4}{3}$ . Their product is 1.

$$\frac{3}{4} \cdot \frac{4}{3}=1$

This equation uses the inverse property of multiplication.

Option B: $\left(-\frac{7}{8}+\frac{7}{8}\right)+4=4$

Inverse of $\frac{-7}{8}$ is $\frac{8}{-7}$

So, it is not true equation.

Option C: $(-5 \cdot 0)-9=-9$

Inverse of $-5$ is $-\frac{1}{5}$ .

So, it is not true equation.

Option D: $\left[7 \cdot\left(\frac{5}{7}-\frac{4}{7}\right)\right]+8=9$

Here also inverse property is not used.

So, it is not true equation.

Hence the equation use the inverse property of multiplication is

$$\left(\frac{3}{4} \cdot \frac{4}{3}\right)+7=8$ .

Find the value of x in the triangle shown below

tino4ka555 [31]

Answer:

x = 32

Step-by-step explanation:

This is an isosceles triangle since two sides have length 10. The angles opposite the congruent sides are congruent. There is an angle measuring 116 deg, and two angles measuring x. The sum of the measures of the angles of a triangle is 180.

x + x + 116 = 180

2x + 116 = 180

2x = 64

x = 32
