Answer: The measurement of angle DBC is 65 degrees

Step-by-step explanation:

Line BD splits ABC into two angles ABD and DBC.

If ABC is 90 then the measures of ABD + DBC will be 90. Since we know the measure of ABD we can make this equation and solve it

$90=25+x\\90-25=25+x-25\\65=x$

Solve for x.

liraira [26]

First one
remember
a/b=c/d also can be written as
ad=bc

so
first one can be rewritten as
3x=96
divide both sides by 3
x=32

2nd ones we can just times both sides by 5 to get
x=50/12

3rd one we times 12 both sides to get
x=8

4th one we translate to
4x=63
divide by 4
x=63/4

5th one we translate to
99=5x
divide by 5
99/5=x

6th one we times 21 both sides
6=x

7th one we times both sides by 16
14=x

last one we translate to
45=3x
divide 3
15=x

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$ .
