1. Add -4.5 to 18.5
2. Divide 23 by 7
3. Then subtract 6 from -2.7
Aimme is right. All the sides are obtuse. They do not equal exactly 90 degrees.
Answer:
7 days
Step-by-step explanation:
2000-600 is 1400.
1400/200 is 7
2000=200x+600
x=7
3x - 2y = 1
2x + 2y = 4
Add the second equation to the first
5x = 5
2x + 2y = 4
Divide the first equation by 5
x = 1
2x + 2y = 4
Subtract the first equation from the second
x = 1
x + 2y = 3
Subtract the first equation from the second again
x = 1
2y = 2
Divide the second equation by 2
x = 1
y = 1
<h3>
So, the solution is x = 1 and y = 1 {or: (1, 1)} </h3>
Answer: 20
Step-by-step explanation:
Given
The cost of an individual ticket is $25
The cost of a couple's ticket is $40
The total sale is $2500
