Multiply each number by 3.
2 (x 3) is 6. 6 x 3 is 18, 18 x 3 is 54, 54 x 3 is 162.
Hope this helps!
Answer:
the ordered pair is (2,-1)
Step-by-step explanation:
We need to solve the system of equations using elimination method
12x - y = 25 eq(1)
9x + y = 17 eq(2)
Adding eq(1) and eq(2)
12x - y = 25
9x + y = 17
___________
21x = 42
x = 42/21
x= 2
Now, putting value of x in equation 1
12x - y = 25
12(2) -y = 25
24 -y = 25
Adding -24 on both sides
24 -y-24 = 25-24
-y = 25-24
-y = 1
Multiply both sides by -1
y = -1
the value of x = 2 and y = -1
So, the ordered pair is (2,-1)
Answer:
a) ![12x = 15000](https://tex.z-dn.net/?f=12x%20%3D%2015000)
b)![x = 1250](https://tex.z-dn.net/?f=x%20%3D%201250)
Step-by-step explanation:
Given: A thrill ride at an amusement park holds a maximum of 12 people per ride.
To find :
a. An inequality that you can use to find the least number of rides needed for 15,000 people.
b. Then find the least number of rides needed for 15,000 people.
Solution :
Let x represent the number of rides.
a) A ride holds maximum of 12 people = 12x
To find an inequality of the least number of rides needed for 15,000 people.
The equation is ![12x = 15000](https://tex.z-dn.net/?f=12x%20%3D%2015000)
b) Find the least number of rides needed for 15,000 people.
Solve the equation,
![12x = 15000](https://tex.z-dn.net/?f=12x%20%3D%2015000)
![x = \frac{15000}{12}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B15000%7D%7B12%7D)
![x = 1250](https://tex.z-dn.net/?f=x%20%3D%201250)
Answer is x=1250
