(3y-20)+(4x-5)+(x+y-10)+(2x+5)=360 (Angles sum of it trapezium)
3y-20+4x-5+x+y-10+2x+5=360

Answer: The correct option is (B) less than 2.
Step-by-step explanation: Given that Y varies directly with X and has a constant rate of change of 6.
We are to find the possible value of X when the value of Y is 11.
Since Y varies directly with X, so we can write
![Y\propto X\\\\\Rightarrow Y=kx~~~~~~~~~~~~~~~(i),~~~~~~~~~\textup{[where 'k' is the constant of variation]}](https://tex.z-dn.net/?f=Y%5Cpropto%20X%5C%5C%5C%5C%5CRightarrow%20Y%3Dkx~~~~~~~~~~~~~~~%28i%29%2C~~~~~~~~~%5Ctextup%7B%5Bwhere%20%27k%27%20is%20the%20constant%20of%20variation%5D%7D)
Since the rate of change is constant and is equal to 6, so we must have
So, from equation (i), we have
Now, when Y = 11, then from equation (ii), we get
Thus, the value of X is less than 2 when Y = 11.
Option (B) is CORRECT.
Answer:
The answer is: Store A is .41 cents per bagel and store B is .45 cents per bagel.
Step-by-step explanation:
Get the dollars per bagel for each store.
Store A is 5 bagels for $2.05.
2.05/5 = .41 cents per bagel.
Store B is 3 bagels for $1.35.
1.35/3 = .45
So store A is the least expensive one.
Hope this Helps! Have an Awesome Day!! (-:
5 - 6 pm
if the temperature drops 3 degrees per hour. so how many hours would it take to go from 98.6 to 86.3
98.6-86.3=12.3
3 goes into 12 4 times.
10 pm - 4 hours is 6pm.
if you figure in the .3
you come to approximately 5pm
That is the vertex form of a quadratic equation
