To solve, use this equation: 2x-5=17
Add five to both sides to get 2x = 22
Divide both sides by 2 to get x=11

you multiply the numbers together
Answer:
Number of ice cream cones = 65
Number of sundaes = 49
Step-by-step explanation:
Let
x = number of ice cream cones
y = number of sundaes
x + y = 114 (1)
2x + 3.5y = 301.50 (2)
From (1)
x = 114 - y
Substitute into (2)
2x + 3.5y = 301.50 (2)
2(114 - y) + 3.5y = 301.50
228 - 2y + 3.5y = 301.50
- 2y + 3.5y = 301.50 - 228
1.5y = 73.50
y = 73.50/1.5
y = 49
Substitute y = 49 into (1)
x + y = 114 (1)
x + 49 = 114
x = 114 - 49
x = 65
Number of ice cream cones = 65
Number of sundaes = 49
Answer:
The points A , B and C lie on the line m . They are collinear.
The points D , B and E lie on the line n . They are collinear.
There is no line that goes through all three points A , B and D . So, they are not collinear.
