<em><u>The GCF ( Greatest Common Factor ) of 12, 28, and 4 is 4</u></em>
Answer:
x < 2
Step-by-step explanation:
→ Expand out brackets
-1 - 6 - 18x > -39 - 2x
→ Simplify
- 7 -18x > -39 - 2x
→ Add -7 to both sides
-18x > -32 - 2x
→ Add -2x to both sides
-16x > -32
→ Solve for x
x < 2
Answer:
-1 5/6
Step-by-step explanation:
-2/3 + (-1 1/6)
Look carefully at he number line. Each space between whole numbers is divided into 6. That means that from one mark on the line to the very next one, the distance is 1/6.
Start at -2/3. Since we are dealing with 1/6's, convert -2/3 to 6ths.
-2/3 * 2/2 = -4/6
-2/3 is the same as -4/6, so start at -4/6. Locate 0 on the number line, and move 4 marks to the left. That is -4/6 which is the same as -2/3 and is your starting point.
Now you need to add -1 1/6. Adding a negative number is the same as subtracting a positive number. Adding -1 1/6 is the same as subtracting 1 1/6. That means you need to go left 1 1/6. Since each unit is divided into 6 equal parts, 1 1/6 is 7 marks on the number line. Starting at -4/6, count 7 marks to the left. Where you end up is the answer which is -1 5/6.
Answer: -2/3 + (-1 1/6) = -1 5/6
Answer: Option a.
Step-by-step explanation:
To solve the given exercise, you must keep on mind the law of logarithms shown below:

Therefore, by applying the law , you can rewrite the expression given, as following:

You know that:

Then, when you substitute values, you obtain:

To determine which answer is correct, apply the given ratio. 1/20:? Just by looking at it we know C is wrong. 4:100 is simplified to 1:25. B is also wrong, as 180:9 is 20:1, which is backwards from 1:20. However, A is correct because 9:180 is 1:20. D is also wrong for the same reasons B and C are wrong. Your answer is A!
