Answer:
Step-by-step explanation:
What we will do is evaluate each of the statements:
Eduardo bought 3 liters of water. This statement may be true, because he was able to buy the water for multiple people or for another use.
2,750 milliliters of sports drink. It is false because the quantity is too small to drink.
2.25 liters of juice. As in the case of water, it can be true if it is to be taken in a group.
Answer:
60
Step-by-step explanation:
Since this angle is unknown, let's just represent it with the variable "x". So the supplement angle of "x" is essentially, the value of the angle that we need to add to "x" to get 180. In other words let's just say that the supplement angle is "y". This means that:
. If we subtract x from both sides we can represent "y" or the supplement angle as:
.
Since it's 660 less than 6 times it's own supplement let's first multiply the supplement by 6

Now let's subtract 660 from it, since it's 660 less

This value should be equal to the angle, which is represented as "x". So let's set it equal to x

Add 6x to both sides

Divide both sides by 7
