Answers

Answer 1
Answer:

Answer: 6 times.


Step-by-step explanation:

Given: Ivan earns $8 every time walks his neighbor's dog.

To earn $81, the number of times he need to walk=(88)/(8)

Therefore, the number of times he need to walk=11

If he already walked the dog 5 times.

Then he need to walk the dog =11-5=6 times

Hence, Ivan  need to walk the dog 6 more times to earn $88.
Answer 2
Answer: He will need to walk the dog 6 more times until he reaches the goal of $88. Have a Brainy Day!!!!

How does using an inverse operation help you solve an equation?
*Please help*

Answers

An inverse set of operations is a pair of operations that do the opposite of each other, such as multiplication and division. When solving an algebraic equation, you can use inverse functions to isolate the variable you are trying to find.
For example:
5x=25
The expression 5x was arrived at by multiplying 5 times x. To reverse that multiplication, you would divide 5x by 5 and get x. However, since this is an equation, you would need to divide both sides of the equation by 5, or else it wouldn't still be equal. The result of dividing both sides is x=5.
As you can see, by taking the inverse operation, you were able to isolate your variable (x) on one side of the equation and therefore solve for its value.
it helps you check the equation to see if you did it right hopefully i helped :}

Given that 2(-x + 4)=3 prove that x=5/2

Answers

Answer:

x = 5/2

Step-by-step explanation:

So firstly, you want to distribute. It'll make your life much easier.

-2x + 8 = 3

-2x = -5 (subtracting 8 from both sides)

x = 5/2 (dividing both sides by -2 to obtain x)

8 meters increased by 25% is how many meters.

Answers

First find 25% of 8
multiply 25/100 or 0.25 by 8. you get 2. This is the same as dividing 8 by 4 (or
8  x 1/4).
Then add that 25%, which is 2, to 8 meters and you get 10 meters
easy peasy :)

hope this helps
Since 25% is 1/4 of 100%, then you do 8/4 and you get 2 and then you do 2 + 8 = 10.

What is the means-to-MAD ratio of the two data sets, expressed as a decimal?Data set Mean Mean absolute deviation (MAD)
1 10.7 2.4
2 13.7 2.5

Answers

The correct answer for the question that is being presented above is this one: 

To find the mean of a set, add up all of the numbers and divide by how many numbers you have. For the first set:
u = (10.7+2.4)/2 = 6.55
For the second set:
u = (13.7 + 2.5)/2 = 8.1

To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean.
First set:
MAD = (|10.7-6.55| + |2.4-6.55|)/2 = 4.15
Second set:
MAD = (|13.7-8.1| + |2.5-8.1|)/2 = 5.6

The means-to-MAD ratio is simply that, divide one by the other and that's it.
For the first set:
6.55 / 4.15 = 1.57831325
For the second set:
8.1 / 5.6 = 1.44642857
