Hello!
First, let's find a common denominator.
9t/15-4t/15
5t/15
t/3
Therefore, our answer is t/3.
I hope this helps!
First number (A): x + 23
Second number (B): 2A - 18
Product = (x + 23)(2A - 18)
= 2Ax - 18x + 46A - 414
Answer:
It is the case of dependent probability sl i think you need to multiply the two probabilities (not sure)
Answer:
3800
Step-by-step explanation:
Variables:
O - Original cost
N - New cost
c - change factor
Step 1:
Recognize that if something decreases by 19%, it is worth 19% <em>less</em>
This means that the new price, fractionally, is 100% - 19% = 81%
So we can use c as 0.81 (81/100)
Step 2:
Write an equation to represent what is happening
N = O * c
Step 3:
Sub in what we know
3078 = O * 0.81
Step 4:
Rearange and solve
O = 3078 / 0.81 = 3800
