Answer:
3
Step-by-step explanation:
Your teacher is correct. The reason is because it is the total cost of both the chocolate and the can… if the choc is $3 and can is $1, you can have 3 chocolate bars because when you add the one can which is one dollar, it equals $10
3x3 = 9
9+1 = 10
Therefore 3 is the answer
Answer:
The given expression is a line equation with slope - 3 and y-intercept 9 .
Step-by-step explanation:
Given expression as
y - 2 = ( - 3) (x - 7)
Now, Rearranging the equation
i,e y - 2 = - 3 x + 7
Or, y = - 3 x + 7 + 2
Or, y = - 3 x + 9
Now, The equation is similar to the equation of any line
∵ <u>The standard equation of any line is written as</u>
y = m x + c
where m is the slope of line and c is the y-intercept
So, while comparing expression with line equation, we get
The equation of line as y = - 3 x + 9
Where - 3 is the slope of line and 9 is the y-intercept
So,The given expression is line equation
Hence, The given expression is a line equation with slope - 3 and y-intercept 9 . Answer
Answer: c = 2
Step-by-step explanation:
First you write out your equation: 10c + 20 = 40
Next, since the equation is adding, you can subtract 20 the constant on both sides of the equation:
10c + 20 = 40
- 20 - 20
The 20s cancel each other out and 40 - 20 is 20.
Our new equation looks like: 10c = 20
Now to find the value of C you are going to divide 10 on both sides because the equation is multiplying.
10c divided by 10 is just c and 20 divided by 10 is 2.
Therefore, you are left with c = 2
hope this helps have a nice day :)
