Answer:
<h3> -5n = 1 ⇒
n = -¹/₅</h3><h3> n+15 = (-10) ⇒ n = 25</h3><h3> n/5 = -1/5 ⇒ n = -1</h3><h3> n-13= -12 ⇒ n = 1</h3>
Step-by-step explanation:
-5n = 1
÷(-5) ÷(-5)
n = -¹/₅
n + 15 = (-10)
-15 -15
n = -25
n/5 = -1/5
×5 ×5
n = -1
n - 13 = -12
+13 +13
n = 1
Answer:
B is the correct answer
Step-by-step explanation:
Let’s write the equation for Tim according to the question, that is t = 14h
Now for sheri, looking at the table, we can see that in two hours, he sells 14 tickets . This means that he sells at an average rate of 7 tickets per hour
Modeling his selling rate, with t being the number of tickets and h being the number of hours, we have;
t = 7h
Tim’s rate is t/h = 14
While sheri’s rate is t/h = 7
We can see that Tim’s rate is double Sheri’s rate

2nd qestions explanation
put value of x=2 in equation as x-2=0 from equation
(2)^3-6(2)^2+a2+10=2
8-24+a2+10=0
2a=-18+24
2a=6
a=3
Answer:
D: 922.3682
Step-by-step explanation:
First you take 1000 and subtract 20 from it.( 2% of 1000 = 1000x0.02x2=20).
You could do this on a calculator by entering 1000 and then subtracting 2% by clicking minus then, 2 then percent, then equals. you get 980. do the same to 980. (click minus, then 2, then percent, then equals). you get 960.4. do the same to 960.4. you get 941.192. do the same one more time since it says t=4 and you get 922.36816 which rounded to the nearest ten-thousandths is 922.3682.
hope this helped!
