Answer:
n = 20
Step-by-step explanation:
n/2 - 9 = 1
Add 9 to each side
n/2 -9+9 = 1+9
n/2 = 10
Multiply by 2 on each side
n/2*2 = 10*2
n = 20
Answer:
The fraction is 7/10 and the decimal is 0.7
Step-by-step explanation:

Answer: (h,k)
Step-by-step explanation: remember that H is your x coordinate and should be the opposite sign of what's in the parenthesis.
10 razors......1 lasts for 1 week...so 10 would last for 10 weeks.
1 week = 7 days...so 10 weeks = 70 days.
6.30 / 70 = 0.09 per day (it would cost 9 cents per day)
Answer:
y = - 3x + 21
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 4 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes , then
y = - 3x + c ← is the partial equation
To find c substitute (7, 0 ) into the partial equation
0 = - 21 + c ⇒ c = 0 + 21 = 21
y = - 3x + 21 ← equation of parallel line
