There is $48 to be divided among 3 people. the ratio of dividing is 3:2:1. How much does the person who receives the most will g
hodyreva [135]

Answer:

The person who receives the most will get $24

Step-by-step explanation:

Let

x ----> amount received by the first person

y ----> amount received by the second person

z ----> amount received by the third person

we know that

x+y+z=48 ----> equation A

x:y:z=3:2:1

so

\frac{x}{y}=\frac{3}{2}

x=1.5y ----> equation B

\frac{y}{z}=\frac{2}{1}

z=0.5y ----> equation C

substitute equation B and equation C in equation A

1.5y+y+0.5y=48

solve for y

3y=48\\y=\$16

Find the value of x

x=1.5(16)=\$24

Find the value of z

z=0.5(16)=\$8

therefore

The person who receives the most will get $24

Multiply 2(x+3)/x(x-1)*4x(x+2)/10(x+3)
KIM [24]

Answer:

The expression simplifies to \frac{4(x+2)}{5(x-1)}.

Step-by-step explanation:

The expression

\frac{2(x+3)}{x(x-1)} *\frac{4x(x+2)}{10(x+3)}

can be rearranged and written as

\frac{8x(x+3)(x+2)}{10x(x-1)(x+3)}.

In this form the (x+3) terms in the numerator and in the denominator cancel to give

\frac{8x(x+2)}{10x(x-1)}.

The x's are present both in the numerator and in the denominator, so they also cancel, and the fraction \frac{8}{10} simplifies to \frac{4}{5}, so finally our expression becomes:

\boxed{\frac{4(x+2)}{5(x-1)}}

Which is our answer:)
