Answer: Its A.) 10y
Step-by-step explanation:
Answer:
1. -3
2. -12
3. 20
4. -15
5. 6
6. -15w+5
7. 10
8. C<-26
9.p> -40
10. P> 16
Step-by-step explanation:
~ -9p -17 = 10
-9p = 27
P = -3
~ x/4 -5 = -8
x/4 = -3
x = -12
~ p/5 +6 =10
p/5 = 4
p = 20
~ -2(m-30) =-6m
-2m+60=-6m
4m = -60
m = -15
~ 3n +2=8+2n
n = 6
Answer:
Step-by-step explanation:
In order to figure out how much money was left in the account after the interest was withdrawn, we have to first find out how much money was initially deposited to earn that amount of interest! The means to find that initial investment is found in the simple interest formula
prt = I, where
p is the initial investement,
r is the interest rate in decimal form,
t is the time in years, and
I is the interest earned. Notice that we have all those things but the p.
Filling in:
p(.0425)(4) = 2380 and
.17p = 2380 so
p = 14000
That means that 14000 was initially invested. If the depositor withdrew the 2380, then
14000 - 2380 is the amount left in the account, namely, $11620
You can write a system of equations, I'm pretty sure.
the first equation would be
10a+3f+.5c=100
and
a+f+c=100
For the first equation, its the price of each ticket that adds up to 100 tickets
For the second equation, its the amount of people that adds up to 100 people.
I'm pretty sure this is the route to go but I haven't solved it for myself (yet) I'll probably comment the answer if you need me to
