Answer:
The answer in the procedure
Step-by-step explanation:
we have
2x-3y=-1 ----> equation A
3x+3y=26 --> equation B
Solve the system by elimination
Adds equation A and equation B
2x-3y=-1
3x+3y=26
----------------
2x+3x=-1+26
5x=25
x=25/5
x=5
Find the value of y
substitute the value of x in equation A or equation B and solve for y
2(5)-3y=-1
10-3y=-1
3y=10+1
y=11/3
Hello,
-a²+12a=0
a²-12a=0
a(a-12)=0
a=0 or a-12=0
a=0 or a=12
The solution are: a=0 or a=12
A = b - 2
a - 3b = 22
(b - 2) - 3b = 22
b - 2 - 3b = 22
-2 - 2b = 22
-2b = 24
-b = 12
b = -12
a = b - 2
a = -12 - 2
a = -14
Solution set {-14, -12}
Answer:
x = 31
ROS = 62
Step-by-step explanation:
QOR + ROS = 90 degrees as indicated by the box
28+ 2x = 90
Subtract 28 from each side
2x = 90 -28
2x = 62
Divide by 2
2x/2 = 62/2
x = 31
ROS = 2x = 2*31 = 62
Let's start with an example.
At the market, 8 batteries cost $10.
How much do 6 batteries cost?
We’re trying to find the cost of 6 batteries.
Batteries Cost
8 / 8 = 1 $10/ 8 = $1.25
If 8 batteries cost $10, then 11 battery costs $1.25.
Batteries Cost
8 $10
1 x 6 $1.25 x 6
6 $7.50
So, 6 batteries cost $7.50.
Back to your question...
We are trying to find the rate of fair which means the fair price for 1 person
Fair Person
18/3 3/3
6 1
So, the fair owner will make $6 for 1 person.
Hope this helped! Good luck!
