Answer:

z = -b - 17 / ( a + 4 )

az + 17 = -4z – b

collect like terms

az + 4z = -b -17

z( a + 4 ) = - b - 17

Divide both sides by ( a  + 4 )

z = -b - 17 / ( a + 4 )

mrs.smith owned one square mile of land. when she moved she gave an equal part of the land to her 3 children,amy,brianna ,and ch
Black_prince [1.1K]

Mrs.smith divided one square mile of land to her 3 children,amy,brianna ,and chad.

1 mile is divided among each children . so the fraction of land each one get is \frac{1}{3}

Amy's land = \frac{1}{3}

Brianna's land = \frac{1}{3}

Chad's land = \frac{1}{3}

Amy decided to divide her portion of the land equally between her 2 children.

We know Amys land = 1/3

1/3 is divided among two children so we divide the fraction by 2

\frac{\frac{1}{3}}{2}= \frac{1}{3} * \frac{1}{2}

= \frac{1}{6}

\frac{1}{6} fraction of mrs. smith's land one of amy's children own.

Chad divided his land equally among his 6 children

We know Amys land = 1/3

1/3 is divided among 6 children so we divide the fraction by 6

\frac{\frac{1}{3}}{6}= \frac{1}{3} * \frac{1}{6}

= \frac{1}{18}

\frac{1}{18} fraction of mrs. smith's land one of Chad's children own.
