10x10= 100
10x10x10=1000
100+1000=10,000
Step-by-step explanation:
Let's start by defining our term:
How much she had at the beginning = B
Now let's edit that value like the problem says
B - B/4 - B/8 = 40
Let's multiply everything by 8 to get rid of any denominators
8B - 2B - B = 320
5B = 320
B = 64
Answer:
Rachel had $64 at the beginning.
Answer:
y = 30
Step-by-step explanation:
If y varies directly with x, then you can make a ratio:
24/8
Simplify the ratio:
3/1
Y is always the first number/ on top in a ratio, that's where I get 24 over 8
3/1 means that y is triple x
so 10 * 3 is 30
