Answer:
126 degrees
Step-by-step explanation:
Triangle: y = 180 - (5x + 4x)
Straight angle: y = 180 - (4x + 30)
180 - (5x + 4x) = 180 - (4x + 30)
5x + 4x = 4x + 30
5x = 30
x = 6
Angle:
y = 180 - (5x + 4x)
y = 180 - 9x
y = 180 - 9(6)
y = 126
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.
There are 14 girls in class five.
<h3>How many of the students are girls?</h3>
28 students were present in class five, such that 18 of them were boys.
The number of girls on Sunday is given by the difference:
28 - 18 = 10
And we know that 4 girls did not go to school on that day, so the total number of girls on class five is:
10 + 4 = 14
