Answer:
Distance Maria had to walk in the afternoon is 
Step-by-step explanation:
Lets take that Maria walked
miles in the afternoon.
Distance walked in the morning + distance walked in the afternoon = 
⇒







(3x + 5)° + (10x - 7)° = 180°
13x + (-2) = 180
13x = 180 + 2
13x = 182
x = 14
∠QRT = 3 * 14 + 5 = 42 + 5 = 47°
∠TRS = 10 * 14 - 7 = 140 - 7 = 133°
Answer:
A. It would become a different atom.
C. Its charge would increase by 1
Step-by-step explanation:
Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
Answer: 69
Step-by-step explanation:
Let the original employee be x , this means that
116% of x = 80
= 80
116x = 8000
divide through by 116
x = 8000/116
x = 68.96551724
Since we are dealing with employees , therefore x ≈ 69
This means that there were 69 employees originally
Answer:
4 packages
Step-by-step explanation:
If there are 20 and stickers are sold in 15 sheets, then you got to work backwards. take the answer and multiply it by the amount of sheets. For example: 4 times 15 is 60, 60 divided by 20 is 3. No leftover numbers.
