3x + 40 = 11x -24<br><br> What does x equal?
pogonyaev
First, you would have to do 11x + 3x Since you're combining like terms.

Now your problem is 14x + 40 = -24

Now you would do 40 - -24 which is now 40+24 and equal to 64.

Now you divide 14 by 64 and you get 4.5

A red kangaroo hops at an average speed of 20km per hour. How fast is this in meters per minute?
masya89 [10]

Answer:

333.3 meters per minute

Step-by-step explanation:

<u>The best way to solve this problem is using </u><u>dimensional anaysis</u><u>. First, we write out our starting units, that being 20km/1hr. We have to keep in mind that we want to change the kilometers to meters and the hours to minutes.</u>

\frac{20km}{1hr}

<u>We know that there are 1000 meters in 1 kilometer. We add this to the dimensional analysis as 1000m/1km. We write it as this because we want the kilometers to cancel each other out. We only want the meters.</u>

= \frac{20km}{1hr} *\frac{1000m}{1km} ...

<u>We also know that 1 hour is 60 minutes. We add this to the analysis as well so that the hours cancel each other.</u>

= \frac{20km}{1hr} *\frac{1000m}{1km} * \frac{1hr}{60min}

<u>We now solve this expression. Since both the kilometers and the hours cancel out, we have meters per minute as our unit. All that's left are the numbers.</u>

= (20*1000*1)/(1*1*60) m/min

= 333.3 meters per minute

What's 80÷7 I need this answer fast thank you it's for 65 points
klemol [59]
In order to solve this, we must find out how many times 7 goes into 80. We can do this by either subtracting individual 7s from 80, or by adding 7s together until we cannot add another without going past 80.

For this answer, I will use the addition method.

7 + 7 = 14

14 + 7 = 21

21 + 7 = 28

28 + 7 = 35

35 + 7 = 42

42 + 7 = 49

49 + 7 = 56

56 + 7 = 63

63 + 7 = 70

70 + 7 = 77

From 77, we cannot add another 7 to it without going over 80, since 77 + 7 = 84.

So, let's count the sevens that we have added up so far, and when we do, we can see that there are 11 of them, adding up to 77.
So 7 goes into 80 11 times. Now, let's find the remainder...

To find the remainder, you just need to subtract the final added number from the number you are dividing from.

80 - 77 = 3

80 / 7 = 11, remainder 3
Hope that helped! =)

Question is on picture
Vlad1618 [11]

Answer:

The expression is half the value of (10 + 12)

Step-by-step explanation:

We see the top part is 10 + 12

The whole thing is a fraction and 2 is in the denominator

You divide your term by your denominator, and diving by 2 is the same as 1/2 if a term.
