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:

$y = z + 7$

$z = y - 7$

$z = x - 11 - 7$

$z = x - 18$

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.

Plz help me i really need it

Vika [28.1K]

Assuming the bank is using simple interest, and not compound interest, then

i = P*r*t

i = 7500*0.06*6

i = 2700

is the amount of money Cheryl earns in simple interest. This adds onto the original amount deposited (7500) to get 7500+2700 = 10200

<h3>Answer: 10200</h3>

Help me out please?<br>chapter : exponents and powers

belka [17]

Answer:

$\frac{125}{27}$

Step-by-step explanation:

$\frac{2^{-4} \times 15^{-3} \times 625}{5^2 \times 10^{-4}}$

Lets expand all the composite numbers into prime numbers.

$=> \frac{2^{-4} \times (3^{-3} \times 5^{-3}) \times 5^4}{5^2 \times (2^{-4} \times 5^{-4})}$

Lets cancel $2^{-4}$ from numerator and denominator.

$=> \frac{3^{-3} \times 5^{-3} \times 5^4}{5^2 \times 5^{-4}}$

Using laws of exponents , lets solve this.

$=> \frac{3^{-3} \times 5^{(-3 + 4)}}{5^{( 2 - 4)}}$

$=> \frac{3^{-3} \times 5^{1}}{5^{-2}}$

$=> 3^{-3} \times 5^{[1 - (-2)]}$

$=> 3^{-3} \times 5^{3}$

$=> \frac{5^3}{3^3} = \frac{125}{27}$
