FIND THE SOLUTION OF EACH EQUATION IF THE REPLACEMENT SETS ARE
1 answer:
1) There are no solutions for this equation in the solution set.
2) The solution set is {5} because 15/5 = 3
3) The solution set is {8} because
4) The solution set is {20} because 20 - 13 = 7
5) The solution set is {66} because 22 x 3 = 66
6)
7)
8)
9)
10)
11) The solution set is {6, 7} because:
6 -2 < 6, which is 4 < 6
AND
7 - 2 < 6, which is 5 < 6
12) The solution set is {9, 11} because:
3 ≥ 25/9, which is 3 ≥ 2.77777777778
AND
3 ≥ 25/11, which is 3 ≥ 2.2727272727
Hope this helps :D

To be able to quickly solve this, we can temporarily make 5.47 into 547
Now, we can divide 547 by 12.
Now, we can round up from 45.5 to get 46.
However, we originally moved our decimal 2 places over, so now we must move it 2 places again.
46 ⇒ 0.46
The correct answer is $0.46
Answer:
(a) 0.00000221 (b) 4.2 x
Step-by-step explanation:
(a) means you need to move the decimal left (because of the negative) 6 spaces. So you have 2.21 move the decimal 6 spaces left and you end up with 0.00000221
(b) If you have 420,000 and you count 5 spaces from the last number, that leaves the decimal inbetween the 4 and 2 so your answer will be 4.2 x
