25% because 19+57= a total of 76 students and the percentage of 19 out of 76 is 25%.
19/76= 0.25
Answer:
The answer to your question is:
Step-by-step explanation:
1.-
y = 84°
5x - 61 = 84
5x = 84 + 61
5x = 145
x = 29
2.-
m∠1 + m∠6 = 180 they are supplementary angles
∠1 = 180 - 143
∠1 = 37
∠1 = ∠ 3 because are vertical angles.
3.-
m∠2 + m∠5 = 180 they are supplementary angles
∠2 + 79 = 180
∠2 = 180 - 79
∠2 = 101
m∠3 = m∠5 they are alternate angles
The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality
Answer: 150c + 400t ≥ 4900
Step-by-step explanation:
Let the number of chairs sold = c
Let the number of tables sold = t
Price for each chair = $150
Price for each table = $400
The inequality that could represent the number of tables and chairs sold will be:
(150 × c) + (400 × t) ≥ 4900
150c + 400t ≥ 4900
Sorry I would have helped but just now seen this. Hope you got it correct
