No the answer is not always postive. For example. If you had -50 and subtracted -30 you would have -20.
Answer:
36x-3y+4z^2+26-7x^2
Step-by-step explanation:
Okay well for starters, you can't subtract that because it's an expression, not an equation. And secondly, there was '?' which I'm going to assue=me was a typing error.
Now to actually simplify this mess of an expression, you just need to combine the like-terms! Once you do that you really can't do anything else, since you don't know the varibles.
Answer:
6x -y = -27
Step-by-step explanation:
y + 3 = 6(x + 5)
Distribute
y+3 = 6x+30
Bring the 6x to the left side by subtracting 6x from both sides
-6x+y +3 = 6x-6x+30
-6x+y +3 = 30
Subtract 3 from each side
-6x+y +3-3 = 30-3
-6x+y-3+3 = 30-3
-6x+y = 27
We usually have the x term positive, do multiply by -1
6x -y = -27
It is given that Total Calories in the meal = 333
Calories per Grilled Chicken Strip = 110
# of Grilled Chicken Strips = x
Calories per Carrot = 29
# of Carrots = y
So the above information can be represented as:
Total Calories = (Calories per Grilled Chicken Strip × Number of Chicken Strips) + (Calories per Carrot × Number of Carrots)
Substituting the values in the above equation.
⇒ 333 = 110 × x + 29 × y
⇒ 110 × x + 29 × y = 333. This equation is in standard form, as an equation in standard form has the format Ax + By = C.
Out of the below options
(A) 110y = –29x + 333
(B) 29x + 110y = 333
(C) 29y = –110x + 333
(D) 110x + 29y = 333
So the standard form of equation matches with option (D), and hence the correct answer is 110x + 29y = 333
