3 km because 2 1/4 divided by 3/4 = 3

Answer: If they maintain the same pace for 2 hours they will go 6 km far.

Step-by-step explanation:

Hi, to solve this problem first we have to calculate the speed rate.

We have to apply the formula ⇒ speed = distance / time

2 1/4 km ÷ 3/4 h = 3 km per hour

Now that we have the rate, we simply have to multiply it by the time they will walk (2 hours) to calculate how far they will go.

2h x 3kmph = 6 km

If they maintain the same pace for 2 hours they will go 6 km far.

Solve each compound inequality. Graph your solutions.<br> 5 + m > 4 or 7m< -35

Yuliya22 [10]

Answer:

Solving the inequality $5 + m > 4\: or\: 7m< -35$ we get $\mathbf{m>-1\:or\: \:m$

The graph of the inequality is shown in figure attached.

Step-by-step explanation:

We need to Solve each compound inequality $5 + m > 4\: or\: 7m< -35$

Solving the inequalities

For solving compound inequalities we solve both inequalities simultaneously and find the value of m.

For solving 5+m > 4, we subtract 5 from both sides.

While solving 7m < -35, we divide both sides by 7 to get value of m

Applying these functions we get:

$5 + m > 4\: or\: 7m< -35\\m>4-5\:or\:m-1\:or\:m$

So, solving the inequality $5 + m > 4\: or\: 7m< -35$ we get $\mathbf{m>-1\:or\: \:m$

The graph of the inequality is shown in figure attached.

Given n//p m<2=50 degrees what is m<7?

Bogdan [553]

Answer: m∠7=130°

Step-by-step explanation:

If two parallel lines are cut by another line (transversal), each one will have four angles surrounding the intersection.

By definition, the adjacent angles of each parallel line, are supplementary, this means that they add up 180°.

Then, if m∠2=50°, then m∠3 is:

m∠3 $=180-50=130$ °

By definition, the angles that are in the same relative position are know as corresponding angles and they are congruent.

Therefore:

m∠3=m∠7

m∠7=130°
