Chukwu, Abdul and kunle are to share $142, such that Abdul gets $11.00 less than Chukwu and $7.00 more than Kunle. How much is C
Elena-2011 [213]

Answer:

Chukwu's share is of $57.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

Chukwu's share is x.

Abdul's share is y.

Kunle's share is z.

Chukwu, Abdul and kunle are to share $142

This means that x + y + z = 142

Abdul gets $11.00 less than Chukwu

This means that:

y = x - 11

$7.00 more than Kunle.

This means that:

y = z + 7

So

z = y - 7

z = x - 11 - 7

z = x - 18

How much is Chukwu's share?

We want to find x, so:

x + y + z = 142

x + x - 11 + x - 18 = 142

3x - 29 = 142

3x = 171

x = \frac{171}{3}

x = 57

Chukwu's share is of $57.

On a map, two locations are 0.75 centimeter apart. Their actual distance is 15 kilometers apart.
egoroff_w [7]
If you are working out the number of KM per CM them you divide the KM by the CM:
15/0.75 = 20

This means that it is 20KM per every 1CM

Hope this helps! :)

Virty [35]

Answer:

Step-by-step explanation:

Mean: You just add them altogether then divide the sum by how many numbers there are

Median: You put all the numbers from least to greatest then cross one off on the left and do the same on the right and repeat until there is either one or two numbers left if there are two number then you find the mean of those two numbers, but if you only have one number left then that is your answer

Mode: You find which number is the most common for enstance if there are two 3 and one 4 then 3 would be your answer because there are more 3 than 4

Range: You take the highest number and the lowest number of the set and subtract them and then you have your answer
