Answer:
n = -4
Step-by-step explanation:
You must write and solve a symbolic equation.
n - 6 = 5(n + 2), or
n - 6 = 5n + 10
Combining like terms, we get:
-16 = 4n,
and so n = -4
Answer: d.1.66a
Step-by-step explanation:
Answer:
Positive
Step-by-step explanation:
First make the denominator equal for both fractions.
The LCM of 8 and 5 is 40, so 40 will be the common denominator.
3/8=15/40 and 2/5=16/40
Add them together.
15/40+16/40=31/40
He has 9/40 of his money left, which means 9/40 of the total money=$6.72
Make an equation to solve for how much money he had when he started (x).
6.72/x=9/40
After solving, x= about $29.87
