4x - y = 18
b. The equation 2/3(x + 400 + 350) = x can be used to model the situation.
c. Leena consumed 500 calories at dinner.
d. The equation 2/3(x) = x(400 + 300) can be used to model the situation.
e. Leena consumed 1,000 calories at dinner.
f. The equation 2/3x(400 + 300) = x can be used to model the situation.
Only Option 'A' and 'B' are correct.
a) Leena consumed 1,500 calories at dinner.
b) The equation 2/3(x + 400 + 350) = x can be used to model the situation.
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Since, we have given that
Number of calories she consumed at breakfast = 400
Number of calories she consumed at lunch = 350
Now, Let number of calories she consumed at dinner be x
According to question,
She consumes 2/3 of her daily calories at dinner,
So, it becomes,
1/3 x total = 400 + 350
total = 2250
so, Number of calories she consumed at dinner is given by
2/3 of total = x
2/3 x 2250 = x
x = 1500
And by option 'B' we get,
2/3 (x + 400 + 350) = x
2 (x + 750) = 3x
2x + 1500 = 3x
x = 1500
So, only Option 'A' and 'B' are correct.

represents the cost of purchasing 5 lip glosses? (1 point)
C (5)=5
1=5
C (5)
C (1) = 5
Answer:
Therefore, the cost of purchasing 5 lip glosses, as represented by the function C(5), is 41.
Step-by-step explanation:
To find the cost of purchasing 5 lip glosses, we need to use the given function C(1) = 31 + 2, which represents the cost of ordering one lip gloss including the flat rate shipping charge. To find the cost of purchasing 5 lip glosses, we can substitute 5 for the variable in the function: C(5) = 31 + 2 * 5 C(5) = 31 + 10 C(5) = 41
The cost of purchasing 5 lip glosses represented in the function C(1)=31+2 is evaluated as C(5)=31+2*5, which equals 41 units.
This question involves the mathematical concept of functions, specifically, simple linear functions. In this example, we have the function C(1)=31+2, which informs us that the cost to order one lip gloss, denoted as 'L', is '31 plus twice the number of lip glosses ordered'
To answer the question 'What represents the cost of purchasing 5 lip glosses?', we substitute the number of lip glosses we want to buy (5) into our function. So instead of evaluating C(1), we evaluate C(5)=31+2*5, following the same structure of '31 plus twice the number of lip glosses ordered'. The solution to this would be C(5)=41, meaning it would cost 41 units (the currency isn't stated) for 5 lip glosses.
