Answer:
x=0
Step-by-step explanation:
30x=60-60
Or,30x=0
or,x=0/30
or,x=0
Answer: The required constant of proportionality is 10.
Step-by-step explanation: Given that y is directly proportional to x, and y = 150 when x = 15.
We are to find the constant of proportionality.
According to the given information, we can write
![y\propto x\\\\\Rightarrow y=kx~~~~~~~~~~~~~~~~[\textup{where k is the constsnt of propotionality}].](https://tex.z-dn.net/?f=y%5Cpropto%20x%5C%5C%5C%5C%5CRightarrow%20y%3Dkx~~~~~~~~~~~~~~~~%5B%5Ctextup%7Bwhere%20k%20is%20the%20constsnt%20of%20propotionality%7D%5D.)
When y = 150 and x = 15, we get from the above equation that

Thus, the required constant of proportionality is 10.

Step-by-step explanation:
One way to find the correct symbol is
Cross Multiply:
⊂⊃ 
Don't know how to cross multiply?
Answer to cross multiply - Multiplying the numerator of the left-hand fraction by the denominator of the right-hand fraction. That the first step. After that, multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction. Which is shown below in picture.
Now let's start:

1 × 4 = 4
1 × 3 = 3
Thus we have:

4 is bigger than 3
Thus the correct symbol is:
<u><em>Kavinsky</em></u>
Answer:
1. x+14 = 17
2. x+10 = 114
3. x-12 = 20
4. 10(x/2+6) =8
5. 2(l+2b) = 126feet
6. 175$-120$ = 50$
