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)
Answer: s + d = T
Step-by-step explanation:
You have to add s and d together to get T.
Furthermore, for Friday you must subtract, T - s = d.
Answer:
2nd option
Step-by-step explanation:
let the number be n then 7 less than this number is n - 7 , so
n - 7 = 16
Answer:
Suppose U={1,2,3,4,5,6,7,8,9,10} is the universal set and M={7,8,9,10}. What is M'?
A. {1,2,3,4,5,6}
B. {1,2,3,4,5,6,7,8,9,10}
C. cannot be determined
D. {7,8,9,10}
My answer is D.
Step-by-step explanation:
M' means the complement of M.
M' will encompass all the elements in the universal set but NOT in the set M.
