Identify the algebraic expression for the following: the quotient of 12 and a number y increased by 7

Goshia [24]

The algebraic expression for the given word problem is 12/y + 7

<h3>Writing an expression</h3>

From the question, we are to write the algebraic expression for the given word problem

The given word problem is

"the quotient of 12 and a number y increased by 7"

First,

"the quotient of 12 and a number y" can be expressed as

12/y

Then,

"the quotient of 12 and a number y increased by 7" becomes

12/y + 7

Hence, the algebraic expression for the given word problem is 12/y + 7

attashe74 [19]

Answer:

Baxter drives at 57 kilometers per hour.

Step-by-step explanation:

In order to find the answer, you have to use the following formula to calculate the speed:

speed=distance/time

distance=399 km

time=7 hours

Now, you have to replace the values in the formula:

speed=399 km/7 hours

speed=57 km/hour

According to this, the answer is that Baxter drives at 57 kilometers per hour.

If m< LMP is 11 degrees more than m< NMP and m< NML =137, find each measure

Agata [3.3K]

First, note that for angles LMP and NMP you have

$m\angle LMP+m\angle NMP=m\angle NML.$

If $m\angle LMP$ is $11^{\circ}$ more than $m\angle MNP,$ then

$m\angle LMP=m\angle NMP+11^{\circ}.$

Now, since $m\angle MNL=137^{\circ},$ you have

$137^{\circ}=m\angle NMP+11^{\circ}+m\angle NMP,\\ \\2m\angle NMP=137^{\circ}-11^{\circ}=126^{\circ},\\ \\m\angle NMP=63^{\circ}.$

Therefore,

$m\angle LMP=63^{\circ}+11^{\circ}=74^{\circ}.$

Answer: $m\angle LMP=74^{\circ},\ m\angle NMP=63^{\circ}.$
