Answer:
This question was worded weirdly however I am assuming this is algebra and you need the equation. So here- -2(q-3) or -2q+6
Step-by-step explanation:
Distribute the -2, to all the terms in the parenthesis of -2(q-3) you get 2q+6
If you didnt know how to get -2(q-3), -2(multiplied) by q-3, you use parenthesis to make sure you know it is multiplication in front of the parenthesis.
Hope I could help!
Let's say the item starts off at $100.
A 55% decrease means 100%-55% = 45% of the value is still there. The item is now worth 0.45*100 = 45 dollars.
Now increase this by 25%. The long way to do this is to add 25% of 45 onto 45
(25% of 45) + (45) = 0.25*45+45 = 11.25+45 = 56.25
Or, we can multiply 45 by 1.25 since the multiplier 1.25 represents a 25% increase
1.25*45 = 56.25
-----------------------------------------------------
The item was $100, it drops to $45 after the 55% decrease, then it is $56.25 after the 25% increase.
Let's compute the percent difference
A = 100 = old value
B = 56.25 = new value
C = percent difference
C = 100*(B-A)/A
C = 100*(56.25-100)/100
C = -43.75%
The negative C value indicates a percent decrease.
So combining a 55% decrease and a 25% increase leads to an overall decrease of 43.75%
-----------------------------------------------------
A shortcut is to multiply 0.45 and 1.25 to get 0.5625
Then subtract this from 1 to get 1-0.5625 = 0.4375
This is another way to see we have a 43.75% decrease.
14 units. Please give me brainliest.
X is the number.
Then:
36=80% of x
80%=80/100=0.8
We can suggest the following equation:
36=0.8x
0.8x=36
x=36/0.8
x=45
Answer: 36 is 80% of 45
