5h - 9 = -16 + 6h

Combine like terms

5h subtracted from both sides.

-9+16 = -16 + h
+16

-9+16 = 7

h = 7

Answer: h = 7

Which statement is true for the vertical number line? A. -2.5 is located below -3.5 . B. -4.8 is located below 4.8 . C. 3.25 is

meriva

Answer:

B. -4.8 is located below 4.8 . TRUE

Step-by-step explanation:

The vertical line is called the Y - AXIS.

Here also, the integers are expressed as same as the horizontal axis.

.... -5, -4, -3, -2, -1 , 0 , 1 2,3 4,5 ....

In vertical line, If we move above 0, the value INCREASES.

If we move Below 0, the value DECREASES.

Now, consider the given cases:

A. -2.5 is located below -3.5 .

Here, as -3 lies Below -2.

So, -2 > -3 ⇒ -2.5 > -3.5

So, -2.5 is located ABOVE 3.5.

B. -4.8 is located below 4.8 .

Here, as -4 lies Below 4.

So, 4 > -4 ⇒ 4.8 > -4.8

So, -4.8 is located BELOW 4.8.

C. 3.25 is located above 3.75 .

Here, 3.75 > 3.25

⇒ 3.75 is located ABOVE 3.25.

D. -0.5 is located below -1.5 .

Here, as -1.5 lies Below 0.5.

So, -0.5 > -1.5

⇒ -0.5 is located ABOVE -1.5.

E. 0 is located below -0.87 .

Here, as -0.87 lies Below 0.

So,0 > -0.87

⇒ 0 is located ABOVE-0.87.

Ben uses a compass and a straightedge to bisect angle PQR, as shown below: The figure shows two rays QP and QR with a common end

maria [59]

Answer:

The correct option is;

∠AQS ≅ ∠BQS when AS = BS

Step-by-step explanation:

Given that AQ is equal to BQ. When AS is drawn congruent to BS, we have;

QS is congruent to SQ by reflective property

Therefore;

The three sides of triangle QAS are congruent to the three sides of triangle QBS, from which we have;

∠AQS and ∠BQS are corresponding angles, therefore;

∠AQS ≅∠BQS because corresponding angles of congruent triangles are also congruent.

Problem PageQuestion It takes an older pump twice as long to drain a certain pool as it does a newer pump. Working together, it

umka2103 [35]

Answer:

It will take 6 hours for the new pump to drain the pool.

Step-by-step explanation:

As the complete question is not given, the complete question is found online and is attached herewith

Let the rate of new pump is given as x=W/t_1

Let the rate of the old pump is given as y=W/t_2

it is given that the time t_2=2t_1

So by substituting the values of t_2 in the rate equation of y

y=W/2t_1

y=(W/t_1*2)=x/2

Also the total rate of both the pumps is given as W/t3 where t3 is given as 4 hours so the equation becomes

x+y=W/4

x+x/2=W/4

3x/2=W/4

As x=W/t_1

3W/2t_1=W/4

Now as W is same on both sides so

3/2t_1=1/4

12=2t_1

t_1=6 hours

So it will take 6 hours for the new pump to drain the pool.
