Solution: (3x + 4y - 3z) x (3x + 4y + 3z)
Proportions are very simple once you get the hang of them! What you do is cross multiple. :)
1. x/8=5/16
You first start by multiplying x and 16
Then multiply 5 and 8
So now you have 16x=40
Finally divide 16 from each side
You get: x+0.4!
2. 5/12=15/x
Remember to cross-multiply!
Now we have 5x=180
Next divide 5 from each side
You get: x=36!
Answer:
12
Step-by-step explanation:
its direct proportion. 15 divided by 5 is 3 so you must multiply 3 by 4 to get the amount of people, which is 12
Answer:
There are 3 because 12 divided by 4 is 3.
Step-by-step explanation:
Answer:
The constant of proportionality is 54.
k = 54
c as a function of d:
Step-by-step explanation:
We are given the following in the question:
c is inversely proportional to the square of d.
When c = 6, d = 3.
Plugging the values, we get,
Thus, the constant of proportionality is 54.
c as a function of d can be written as:
We have to find value of c when d = 7.
Putting values, we get,
is the required value of c.
