4g/cm^3
D = M/V
100g/25cm^3 = 4g/cm^3
45.87= 2.18 plus 300 is 345.87 hope this is correct if not im soooo sorry
Answer:
Step-by-step explanation:
So basically what you want to do is start with the distributive property.
-0.5(x+0.3) = 1.6x+0.9(x+4.8) would then equal -0.5x-0.15 = 1.6x+0.9x+4.32.
Then, add the matching terms on the right side (the x values) 1.6x+0.9x =2.5x
Your equation should the look like -0.5x-0.15 = 2.5x+4.32.
Next, add -0.5x to 2.5x giving you 3x
The equation will look like -0.15 = 3x+4.32
After that subtract 4.32 from -0.15 leaving you with -4.47=3x
Divide 3x from both sides
Your answer should be x= -1.49.
I hope this was helpful and not super confusing! Also if anything is incorrect let me know! :)
Answer:
28%
Step-by-step explanation:
start with $46 = 100% of starting price
coupon = 40% off starting price
40% off of 100% = 100% - 40% = 60% of starting price = price after coupon
60% = 0.6
60% of starting price = price after coupon = 0.6 * $46 = $27.6
then, a 20% processing fee is applied to the price after the discount
new price = $27.6 = 100% of new price
fee = 20% added to new price
20% added to new price = 100% + 20% = 120% of new price
120% = 1.2
final price = price after fee = 120% of new price = 1.2 * $27.6 = $33.12
change in percentange = (original price - new price) / original price * 100
= ($46 - $33.12) / $46 * 100 = 28%
-27+8
( The minus signs multiply each other to form a +. )
= -19
