one solution
d=-2
Step-by-step explanation:
4(3d - 7) = -52
There is one solution to this equation
Distribute
12d -28 = -52
Add 28 to each side
12d-28+28 = -52+28
12d =-24
Divide each side by 12
12d/12 = -24/12
d = -2
Answer: Step 2 was pam's error
Step-by-step explanation:
The price of the item would be $18 which is 20% of the original price. To find this answer you have to first subtract 100% and 80% since 80% is what is being taken off of the total you need to figure out what percentage of the total you are left with. Which comes out to 20% Once I figured that out i set up a ratio where I made 100% and $90 equal, since that is the original price, and made 20% equal to X, since that is what we are trying to find. I the cross multiplied 20 and 90 and got 1800 I took that number and divided by 100 which gave me $18. This is 20% of $90 when the price has been marked down by 80%. I hope that this helps and that it is not to confusing.
