3.482 x 10^9.
-the coefficient must be under 10, and in this case it is the "3". Then you count the places after that to get your exponent
-4(8-3x)≥6x-8
Expand the left side.
-32+12x≥6x-8
Add 32 to both sides
12x≥6x+24
Subtract 6x.
6x≥24
Divide both sides by 6.
x≥4
Answer: x ≥ 4
Answer:
12 inches
Step-by-step explanation:
when you want to find the original side, you multiply the new side by the scale factor. In this case, 18 and 2/3. And with that you'll get 12 inches
Step-by-step explanation:
This actually depends in different problem but the way I think your talking about is the easiest way.
Problem: 80% of 385
Step 1 You will be Multiplying
Step 2. Move the decimal to the left by 2 places.
Example: 385
x .80
----------
Step 3 do the problem
example: 385
x.80
-----------
308.0% is the percentage
make sure to drop the decimal but if there there nothing after it don't leave it in your final answers ( some teachers mark it wrong when it really it's not wrong just improper format)
