Do distributive property to get rid of the parenthesis
3x + 3 = -2x + 2 + 6
combine like terms
3x + 3 = -2x + 8
move the -2x over by addition
5x + 3 = 8
move the 3 over by subtraction
5x = 5
now divide by 5
x = 1
Answer:
21 phones per min
Step-by-step explanation:
60 (mins in an hour) x 5= 300
6,300 divided by 300= 21
Sin² x + sin x cos x = 0
sin x ( sin x + cos x ) = 0
sin x = 0 ; x 1 = k π ; k ∈ Z
sin x + cos x = 0 / ²
sin² x + 2 sin x cos x + cos² x = 0
2 sin x cos x + 1 =0
sin ( 2 x ) = - 1
x = 3π / 2 + 2 kπ / : 2
x 2 = 3π / 4 + kπ ; k ∈ Z
Answer:
The measure of angle 4 is 48 degrees.
Step-by-step explanation:
When two angles <u>forming an X</u>
- shape share a common vertex and
- oppose each other
the angle has the same value.
We call this type of angles opposing angles or vertical angles.
