X-2/(x-3)=(x-1)/(3-x)
we can make the denomenators the same by multiplyting the left side by -1/-1
-x+2/(3-x)=(x-1)/(3-x)
minus 2/(3-x) from both sides
-x=(x-1-2)/(3-x)
-x=(x-3)/(3-x)
times both sides by 3-x
-x(3-x)=(x-3)
-3x+x^2=x-3
minus x both sides and add 3
x^2-4x+3=0
factor
(x-1)(x-3)=0
set to zero
x-1=0
x=1

x-3=0
x=3

x=1 or 3

Jose set a goal of saving at least $200 in a savings account. He currently has $60 in the
Dovator [93]
It will take him 28 weeks. If he already has $60 of $200 saved, you would do 200 - 60. That would give you 140. To find out how long it would take him to make $140, you would have to do 140 divided by 5 to get the number of weeks.

Michael’s weight can be represented by the expression 72x^5. Al’s weight can be represented by the expression 9x^7.
podryga [215]

Answer:

a) \frac{72x^5}{9x^7}

b) =\frac{8}{x^2}

c), Yes;8x^2

Step-by-step explanation:

Michael's Weight: 72x^5

Al's weight: 9x^7

a) Ratio of Michael's weight to Al's weight: \frac{72x^5}{9x^7}

b) This ratio simplifies to:  \frac{8\times 9x^5}{9x^5\timesx^2}

                                         =\frac{8}{x^2}

c) Yes, If the exponent in each expression were negative, then we have:

Ratio of Michael's weight to Al's weight: \frac{72x^{-5}}{9x^{-7}}

This ratio simplifies to:  8x^{-5--7}=8x^2

The two ratios are not the same.
