Answer:
your answer might be 3
Step-by-step explanation:
An isolated system is a thermodynamic system that cannot exchange either energy or matter outside the boundaries of the system. An isolated system differs from a closed system by the transfer of energy. Closed systems are only closed to matter, energy can be exchanged across the system's boundaries.
Last week, the Glee Club made 437 flowers. They made 322 more this week than last week. So this could be shown in this case as 437 + 759 (since 437 + 322 = 759). This equals 1,196 flowers. To find the remaining number of required flowers, we could represent this equation as 1,196 + x = 1,250, with x representing the number of flowers still needed. Since 1,250 - 1,196 = 54, they still need to make 54 paper flowers for their parade float. Substituted back into the equation, it would look like this:
1,196 + 54 = 1,250.
You add the numbers 69 and 59 and you get your angle measure.
