Solve for x<br><br> (1.) 5/10x-9=8<br><br> (2.) 3/4x-3=1+5/12x

Yakvenalex [24]

Answer:

1). $x=\frac{5}{170}$

2). $x=\frac{1}{12}$

Step-by-step explanation:

(1.) $\frac{5}{10x}-9=8$

adding 9 on both sides we get

$\frac{5}{10x}=9+8$

$\frac{5}{10x}=17$

$5=17 \times 10x$

$x=\frac{5}{170}$

(2.) $\frac{3}{4x}-3=1+\frac{5}{12x}$

$\frac{3}{4x}-\frac{5}{12x}=1+3$

$\frac{9-5}{12x}=4$

$\frac{4}{12x}=4$

$12x=1$

$x=\frac{1}{12}$

You want to sell your house.Your realtor earns 6% of the selling price.Your house sells for 100,000.How much will your realtor e

sp2606 [1]

Hey there! :D

Let's assume that 100,000 is 100%. Now, we have to find what 6% of 100,000 is.
We can do this step by step.
First, figure out what 1% of 100,000 is. To find 1% of a number, move the decimal place 2 places to the left.
So, when we move the decimal 2 places to the left, we have 1000.00. Basically, we have 1000.
So, 1000 is 1% of 100,000. Now, to find 6%, multiply 1000 by 6. So, 1000 multiplied by 6 is 6000. The final answer is 6000. The realtor earns 6000 dollars.
Thank you! Hope it helped!
