Okie, so percent decrease is the amount loss divided by the original number and multiplied by 100 to find the percent. This is because you are finding the amount loss in terms of the total amount - percent basically.
The amount loss : 4 feet
4 feet/ 12 feet = .3333 (ratio of how much cut) multiply by 100 --> 33.3% decrease. From 12 feet to 8 feet is a 33.3 % decrease. I hope this helps :-)
-4(4)=-16
3(1/7)=3/7
I think that’s what you are asking...
Answer:
The expression 3s + 2p represent total price of 3 shirts and 2 pairs of pants.
Step-by-step explanation:
It is given that
Price of a shirt = S dollar
Price of a pair of pants = P
Total number of shirts = 3
Total number of pairs of pants = 2
Total price = Quantity × Price of each unit
Total price of 3 shirts = 3S
Total price of 2 pairs of pants = 2P
Total price of 3 shirts and 2 pairs of pants = 3S + 2P
Therefore the expression 3s + 2p represent total price of 3 shirts and 2 pairs of pants.
First of all you need to get rid of the -27 on the left side, to do so you add 27 to both sides so it becomes:
5/8a=20
Now you can divide it by 5 to get:
1/8a=4
Now multiply it by 8 to get:
a=32
Hope this helps :)
