Start by putting into improper fractions.
- 1 2/3 = - 5/3
- 2 1/5 = - 11/5
Now stack the fractions like this.

Here's the key part (or one of them). Cancel the minus signs. Since there are 2 of them they become a plus.

Now invert the 11/5. That means turn it upside down. Put the 5 in the numerator and 11 in the denominator. Multiply by it by the top fraction.

When you do this, you just multiply top by top and bottom by bottom
Answer:
<h2><u>The amount paid to an employee was </u><u>
162</u></h2>
Step-by-step explanation:
<h2><u>The expression 12h + 30w Identifies the amount paid to an employee.</u></h2><h2><u>Let h represent hours and let w represent the total amount of g-wagons sold. </u></h2><h2><u>Since the question explains that an employee works 6 hours and sells 3 wagons, put h as h = 6 and w as w = 3. We would end up getting this equation. 12h + 30w = 12(6) + 30(3).</u></h2><h2><u>Now all you need to do is solve it.</u></h2><h2><u>left side = 72</u></h2><h2><u>right side = 90</u></h2><h2><u>
72 + 90 =</u><u> 162</u></h2>
2 and 3/5 is your answer.
Answer:
5y + x = 35
Step-by-step explanation:
5y= 10 - x
y = 2 -1/5x
thus gradient m = -1/5
the eqn would be y = -1/5x + 7 or 5y + x = 35
