Answer:
8
Step-by-step explanation:
X - the number
3x - 7 = -4 |add 7 to both sides
3x = 3 |divide both sides by 3
x = 1
If 6 cans of soup cost $1.50
9 cans cost .......................x?
x = 9 * 1.50 / 6
x = 2.25
Answer
9 cans cost $2.25
Answer:

Step-by-step explanation:
We are given the following in the question:
A(1, 1), B(2, 4), C(4, 2)
i) Slope of AB

Thus, slope of AB is 3.
ii) Point slope form
The point slope form of a line can be written as:

The point intercept form of line can be written as:

The line is parallel to AB and contains point C(4, 2). Since line p is parallel to AB, line p will have the same slope as line AB
Putting values, we get,

which is the required slope intercept equation of line p.
7. 65 + 75 = 140
180 - 140 = 40
( I think this is the answer)
