Answer: -4/7
Step-by-step explanation:
2/3 (1 + n ) = -1/2n
2/3 + 2/3n = -1/2n
Multiply both sides by 6
4 + 4n = -3n
4n + 3n = -4
7n = -4
Divide both sides by 7
n = -4/7
Answer:
C. x=-48
Step-by-step explanation:
x/4=-12
multiply both sides by 4
4x/4=4 (-12)
simplify
x=-48
Answer:
Q = -3.4
Step-by-step explanation:
Our original equation is: -13(q+4)=7q+16
if we simplify this, we get: -13q-52=7q+16
Subtract 16 from both sides: -13q-68=7q
Add 13q to both sides to get: -68=20q
divide the equation to get this: -3.4=q
Answer:
The probability is 1/6
Step-by-step explanation:
Firstly, we need to get the total number of coins
that would be the sum of all the coins present
We have this as;
8 + 10 + 4 + 2 = 24 coins
The number of nickels is 4
So the probability of selecting a nickel is the number of nickels divided by the total number of coins
We have this as;
4/24 = 1/6
