The given question is incomplete
Here are some letters and what they represent. All costs are in dollars.
m represents the cost of a main dish.
n represents the number of side dishes.
s represents the cost of a side dish.
t represents the total cost of a meal.
Discuss with a partner: What does each equation mean in this situation? a. a. m = 7.50
b. m = s + 4.50
c . ns = 6
d. m + ns = t
2. Write a new equation that could be true in this situation.
Answer:
t = 3m -n(s+1)
Step-by-step explanation:
Using the information we can describe the value of each letters
using a and b
7.50 = s + 4.50
s = 3
substitute s in c, we get
using equation d we have
- m + ns = t
- 7.50 + 6 = t
- t = 13.50
so we an equation using the above data
t +ns = 3m - n
t = 3m -n(s+1)

I'm struggling with that to sowy T T
The answer should be the same as the question. 5c + 12d -6 is the answer because to simplify,you collect like tersm yet none of these terms are alike to each other ( different variable and exponent) therefore the answer is 5c+12d-6
using the FOIL method the equation gets pretty long
Multiply each term by each term and combine like terms the given equation simplifies to:
f(x) = -2x^5 - 9x^4 - 8x^3 + 15x^2 +28x + 12
The degree is equal to the highest exponent, which is the 5 on -2x^5
The degree is 5
The y intercept is the value of y when x is 0
Replace all the x's with 0 and solve the equation:
f(x) = -2(0)^5- 9(0)^4 - 8(0)^3 + 15(0)^2 +28(0) + 12
= 0 -0 -0 + 0 +0 +12 = 12
The y intercept is (0,12)
Hello!
You can solve this algebraically
7 - 5y = 3y - 17
Add 5y to both sides
7 = 8y - 17
Add 17 to both sides
24 = 8y
Divide both sides by 8
3 = y
The answer is 3
Hope this helps!
