On his death, a wealthy businessman left R132 000 to charity. He declared that the money should be given to the following charit

Nutka1998 [239]

Answer:

The Reach for a Dream Foundation received R33000, NSPCA received R44000, and Smile received R55000.

Step-by-step explanation:

Total money for charity = R132,000

Ratio:

3 : 4 : 5

Charities:

The Reach for a Dream Foundation : NSPCA : Smile

x : y : z

3x + 4y + 5z = R132000

Charity 1 = Charity 2 = Charity 3

x = y = z

3x + 4x + 5x = R132000

x = 11000

The Reach for a Dream Foundation:

3(11000) = R33000

NSPCA:

4(11000) = R44000

Smile:

5(11000) = R55000

Double Check:

R33000 + R44000 + R55000 = R132000

B.y = 4x + 2<br> y = -8x + 8

Inessa05 [86]

$y = 4x + 2 \\ = > y - 2 = 4x \\ = > x = \frac{y - 2}{4}$

$y = - 8x + 8 \\ = > y = - 8( \frac{y - 2}{4} ) + 8 \\ = > y = \frac{ - 8y + 16}{4} + 8 \\ = > y = \frac{ - 8y + 16 + 32}{4} \\ = > y = \frac{ - 8y + 48}{4} \\ = > 4y = - 8y + 48 \\ = > 4y + 8y = 48 \\ = > 12y = 48 \\ = > y = 4$

$y = 4x + 2 \\ = > 4 = 4x + 2 \\ = > 4x = 4 - 2 \\ = > 4x = 2 \\ = > x = \frac{2}{4} = \frac{1}{2}$

<u>Answer:</u>

$x = \frac{1}{2} \\ y = 4$

Subtract the expressions: (5z + 4) - 5(-3z -6)

Anna71 [15]

Hey there!

“(5z – 4) – 5(–3z – 6)”

DISTRIBUTE the RIGHT side of your equation

5z – 4 –5(–3z) + (–5)(–6)

–5(–3) = 15z

(–5)(–6) = 30

NEW EQUATION: 5z – 4 + 15z + 30

COMBINE your LIKE TERMS

(5z + 15z) + (4 + 30)

5z + 15z = 20z

4 + 30 = 34

ANSWER: 20z + 34 ☑️

Good luck on your assignment and enjoy your day!
