Step-by-step explanation:
The silmutenous equations
2/3x + 1/2y = 56
X=y
There are 153 people who each ate 1/4 pounds. Therefore, the amount of watermelon eaten is 153/4 pounds.
The amount of watermelon served is





There is 186/4 total watermelon. Minus the 153/4 that was eaten,

Since Death Valley is below sea level, the hiker increases altitude before stopping at 0 feet.
Percent of increase is given by the formula (amount of change)/(original amount) * 100. Your work is accurate.
Answer:
The inequality x>2 matches the graph.
Step-by-step explanation:
From the graph, it is clear that the shaded graph is heading towards the +ve infinity from the x > 2.
If the inequality includes < or >, we graph the equation as a dotted line.
From the graph, the dotted line indicates that x=2 is not included in the solution of the inequality.
so the interval of the domain of the inequality is: (2, ∞)
Therefore, the inequality x>2 matches the graph.
