Chang and Carlotta solve this problem in two different ways. You have $50 in your bank account. You make $8 per hour mowing lawn

Daniel [21]

Answer:

8 hours

Step-by-step explanation:

You can solve this problem by inputting the values into an equation. Here is the equation below:

$50 + 8x = 130$

Lets solve for x. First you subtract 50 from 130.

1) $8x = 130 - 50$

2) $8x = 80$

Next, you divide 80 by 8 to get x by itself.

1) $x = \frac{80}{8}$

2) $x = 10$

This means that you must mow lawns for 8 more hours to get a total of $130 in your bank account.

Artyom0805 [142]

Answer:

(i) U' = Φ

(ii) A∩A' = Φ

(iii) A – ( B U C) = {5,7,9}

(iv) A' U ( B U C ) = {2,4,6,8,10}

(v) A' U ( B' ∩ C') = {2,4,5,6,7,8,9,10}
