Answer:
The inequality matches the graph is 2n + 5 ≤ 7 ⇒ A
Step-by-step explanation:
Let us solve the question
<em>From the given graph</em>
∵ The arrow starts from 1 and pointed to the left (negative part)
∵ The starting point of the arrow is bold
∴ The sign of the inequality is ≤ (smaller than or equal)
→ That means the solution of the inequality is all the numbers ≤ 1
∴ The solution of the inequality is n ≤ 1
→ Look at the choices and find which one has the sign ≤ and check if
it will give the same solution or not
∵ The inequality is 2n + 5 ≤ 7
→ Subtract 5 from both sides
∴ 2n + 5 - 5 ≤ 7 - 5
∴ 2n ≤ 2
→ Divide both sides by 2
∴ n ≤ 1
∵ The inequality gives the same solution of the given graph
∴ The inequality matches the graph is 2n + 5 ≤ 7
1 km = 1,000m
Victor: 3.5 km = 3,500m
Terrel: 1,250m *3 = 3,750m
Terrel ran a greater total distance

Answer:
x = 8/7
Step-by-step explanation:
3(x - 2) + 6 = 4(2 - x),
3x - 6 + 6 = 8 - 4x,
7x = 8,
x = 8/7
