When combining like terms, always go from left to right.

7x-8x = -1x
9y-4y-5y=0
answer is -1x
Nastasia [14]4 years ago

Simplifying   7x+9y+-8x+-4y+-5y=0

reorder the terms   7x+-8x+9y+-4y+-5y=0

combine like terms  7x+-8x=-1x-1x+9y+-4y+-5y=0

 combine like terms  9y+-4y=5y-1x+5y+-5y=0

combine like terms 5y+-5y=0
-1x+0=0
-1x=0

solving
-1x=0

Express 30 minutes as a percentage of 3 hours 20 minutes​
liberstina [14]

Answer:

15%

Step-by-step explanation:

The quantities must be in the same units

Using the conversion

I hour = 60 minutes, then

3 hours 20 minutes = ( 3 × 60) + 20 = 180 + 20 = 200 minutes.

Thus

\frac{30}{200} × 100% = \frac{30}{2} = 15%

1. The diagram shown is two intersecting lines. The measure of &lt;5is 47°.
Savatey [412]

The measure of ∠7 is 47°. Angle 7 is a vertical angle to angle 5

Suppose the measure of ∠6 is represented represented by (2x - 5), the equation that can be use to solve for x is 42 + 2x = 180

The value of x is 69

<h3>Vertical opposite angles</h3>

Vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines.

Vertical opposite angles are congruent. Therefore,

a. ∠5 ≅ ∠7 (vertical angles)

Therefore, angles 5 and 7 are congruent angles.

∠7 = 47°

b. Suppose ∠6 = 2x - 5 . let's find x

Therefore,

∠5 + ∠6 = 180(angle on a straight line)

The equation to solve the above is as follows:

47 + 2x - 5 = 180

42 + 2x = 180

2x = 180 - 42

2x = 138

x = 138 / 2

x = 69
