The process is to go step-by-step to isolate the y.
To do this, you basically run the order of operations in reverse.
In 5x+2y=10, the first thing to move away from the left side is 5x and you cancel it out by subtracting 5x from both sides:
5x+2y - 5x = 10 - 5x
The 5x's on the left cancel leaving you with:
2y = 10 - 5x
Side note: this is more commonly written as 2y = -5x+10, since we tend to write variable terms first.
Finally, to get the y fully by itself, you need to cancel the 2 that's multplied against it. To cancel multiplication, you need to divide:
The most important thing to remember here is that the 2 needs to divide into both terms on the right:
Finally, we simplify this into:
Answer:
$0.25
Step-by-step explanation:
To find the unit rate of each orange, divide the total cost of the bag by the number of oranges in the bag:
⇒ 3.75 ÷ 15 = 0.25
Therefore, the unit rate of each orange is $0.25
Answer:
hold for a second ill get you an answer
Step-by-step explanation:
7. You have the equator's length of four planets, the distances are given in kilometers
8. Estimation for the Earth: 40.000 km. Jupiter: 400.000. These approximations come from the nearest whole number for each.
9. The relation is that if the Jupiter equator's length is divided by ten, you will get the Earth's equator length, which means that Jupiter's equator is ten times bigger than the earth.
<u><em>Answer: </em></u>
