To solve this problem you can apply the following rule of three:
$ 1,435 ---> 100%
$ 1,595 ---> x
Clearing x we have:
x = ((1595) / (1435)) * (100)
x = 111.1498258
Then, the difference is:
111.1498258 - 100 = 11.14982578%
hundredths of a percent:
11.15%
Answer:
the dealer's price from the Blue Book: It is 11.15%
Answer:
A
Step-by-step explanation:
It's 12.5; (4×x) -9 = 41; 4×x = 41 +9; x = 50 / 4; x = 25/2=12.5
Probe: 12.5 ×4-9 = 50-9=41.
Answer:
y = x / 7
Step-by-step explanation:
For us to get direct variation equation, we must introduce a constant term.
If y varies directly as x:
y ~ x
y = Kx
Where K, is the introduced constant.
Now let's solve to get a direct variation equation.
When y=3 , x=21
We substitute, y=3 and x=21 in the
y = Kx
3 = K 21
Divide both sides by 21
3 / 21 = K 21/ 21
K = 3/21
K = 1 / 7
Therefore, we introduce K = 1 / 7 into the mother equation.
y = 1/7 * x
y = x / 7
The direct variation equation for the situation:
y = x / 7
The square root of 36 is 6, because 6 X 6 equals 36.
Hope this much helps you out!
