if you have already covered slopes, you could also get it that way, in fact is simpler that way.
180 + 30x = 60 + 50x
⇒ 20x = 120
⇒ x = 6 minutes

Answer:
A : 25
Step-by-step explanation:
In a neutral atom, the number of electrons is equal to the number of protons. The atomic number indicates the number of protons.
The mass number is the sum of the number of neutrons and the number of protons.
mass number=protons+neutrons
As we know from the atomic number, the number of neutrons is 14 and the number of electrons is 11.
mass number = 14 + 11
Answer: -2x + 12
Step-by-step explanation:
2A + B = 2(-2x + 8) + (2x - 4) = -4x + 16 + 2x - 4 = -2x + 12
Answer:
3x-5 and r=0
Step-by-step explanation:
We can do it by long division method the required quotient is 3x-5 and r=0
not 3x-1 , r=1
multiply the divisor with 3x we will get to cancel out the first term of dividend
Now after solving we will get
Now, multiply the divisor by -5 we will get -5x-15 which will cancel the entire dividend.
