Answer: -7
Step-by-step explanation:
-30 = 5(x + 1)
-30 = 5x + 5. ( After distrbuting the 5)
-5. -5
-30 - 5. = 5x
-35 = 5x
x = -7
Part A: One solution because the lines intersect one time.
Part B: (3,4) or x=3 and y=4 (depending on how you have to write it)

<u>Answer:</u>
The element is Chromium.
<u>Explanation:</u>
The atom has 24 protons and 12 neutrons.
We know that Cr has 24 number of protons, to the Chemical is Cr (Chromium)
Again, we know that the atomic number is the number of protons and the atomic mass is the sum of proton and neutron.
So, the atomic number is 24 and the atomic mass is (24+12)= 36
Therefore, the symbol is
