Answer:
The total charge in an atom is zero or it is neutrally charge. both nulify each others charge.
- If the atom has some charge in it then it is called an ion.
Answer:
21b-32+7b-20b
7b-32
Step-by-step explanation:
35% are in display cases which means 65% are on the wall.
this means 195 cars is 65% of the collection.
to get total number of cars in the collection divide 195 by 65%
195/0.65 = 300
answer: 300 total cars
Answer:
y = x
Step-by-step explanation:
Slope-intercept form is the form that looks like
... y = mx + b . . . . . . for slope m and y-intercept b
The line connecting points D and E has slope 1 and y-intercept 0, so the equation is ...
... y = 1·x + 0
... y = x . . . . . . without the identity elements
_____
<em>Comment on the marked choice</em>
The choice that is marked is the equation in <em>point-slope form</em> using the point E (4, 4). That is not the form requested by the problem.
Answer:
The measure of angle A is 53 degrees
The measure of angle B is 37 degrees
Step-by-step explanation:
Here in this question, we are interested in calculating the measure of the two angle.
When how angles are complementary, it means the sum of both equals 90 degrees
mathematically ;
(7x + 4) + (4x + 9) = 90
7x + 4x + 4 + 9 = 90
11x + 13 = 90
11x = 90-13
11x = 77
x = 77/11 = 7
The measure of angle A = 7x + 4 = 7(7) + 4 = 49 + 4 = 53 degrees
The measure of B = 4x + 9 = 4(7) + 9 = 28 + 9 = 37 degrees
