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.
Its algebra. The original equation is 
To solve for a variable, we reverse the order of operations, beginning with addition/subtraction, and then multiplication/division. To remove a number from one side, we must do the opposite to the other side. In this case, to get rid of the -121 we must add 121 to the -164. This gives us -43. Then, to get the x by itself, we must multiply the other side by 3. -43*3=129
When we are doing the opposite of an operation to the other side, we are really reversing the operation and, to keep both sides equal, we must do whatever we have done to one side to the other side. So when we have -121, we add 121 as it equals 0, therefore it is gone. Since a equation must be balanced, we have to do what we did to the other side (adding 121).
