<h3>Solution:</h3>
-38d - 57 = -19d + 76
or, -38d + 19d = 76 + 57
or, -19d = 133
or, d = 133/-19 = -7
<h2>Answer: d = -7</h2>
<h3>To Check:</h3>
By putting the value of d, we get
-38(-7) - 57 ≥ -19(-7) + 76
or, 266 - 57 ≥ 133 + 76
or, 209 ≥ 209
Hence, Verified.
Use the distance formula to find the lengths of the sides
Answer:
Step-by-step explanation:
Let's take for example the first one Al(C2H2O2)
If there is no subscript under the number, the amount of atoms is 1
If we have a subscript, as in this case, the subscript is the number of atoms.
In the example above, there is 1 atom of Aluminium, two of Carbon, two of Hydrogen and 2 of Oxygen. If you have parenthesis and number before them, e.g., 4(Al2O3), you just multiply the parenthesis by the number in front of them, which means 4*2=8 aluminium atoms, 3*4=12 oxygen atoms, the same applies if the number is subscript behind the parenthesis like in fourth example.
30x2 - 5x + 60x - 10
30x2 + 55x -10
The value of x from the figure is 30 degrees
<h3>Parallel lines</h3>
Parallel lines are lines that have the same slope and have 0 degrees as the angle between them.
The sum of angle 5 and angle 6 are supplementary. Hence;
m<5 + m<6 = 180
3x - 33 + 123 = 180
3x + 90 = 180
3x = 180 - 90
3x = 90
Divide both sides by 3
3x/3 = 90/3
x = 30
Hence the value of x from the figure is 30 degrees
