Answer:
The number of onion rings is <u>3</u> in the combination meal and the number of sliders is <u>2</u> in the combination meal.
Step-by-step explanation:
Given:
At a particular restaurant, each onion ring has 65 calories and each slider has 250 calories. A combination meal with onion rings and sliders has a total of 5 onion rings and sliders altogether and contains 695 calories.
Now, to find the number of onion rings in the combination meal and the number of sliders in the combination meal.
Let the number of onion rings in the combination meal be
And let the number of sliders in the combination meal be
<u><em>So, the total number of onion rings and sliders are:</em></u>
Now, the total number of calories each onion rings and sliders has:
Substituting the value of from equation (1) we get:
<em /><em />
<em>Subtracting both sides by 1250 we get:</em>
<em /><em />
<em>Dividing both sides by -185 we get:</em>
<u><em>The number of onion rings in the combination meal = 3.</em></u>
Now, substituting the value of in equation (1) we get:
<u><em>The number of sliders in the combination meal = 2.</em></u>
Hence, the number of onion rings is 3 in the combination meal and the number of sliders is 2 in the combination meal.
Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
we have the point (-30,18)
so
x=-30, y=18
Find the value of k
substitute
Simplify
Divide by 6 both numerator and denominator
