Let "radical 2" be represented by "r."
Then you are to simplify 4r + 7r - 3r. This comes out to 11r - 3r = 8r.
The answer is 8 radical 2.
Answer: Our required equation would be
Step-by-step explanation:
Since we have given that
y=30, when x = 6.
As there is direct proportion between x and y.
so, it becomes,
So, the equation connecting y and x would be
When we put the value of k, we get that
Hence, our required equation would be y=5x

Answer:
234.5
Step-by-step explanation:
Answer:
c + 2d = $7.00
2c + 3d = $12.00
Step-by-step explanation:
Hello!
<u>Let:</u>
- c = # of coffees
- d = # of donuts
1 coffee and 2 donuts cost $7.00
This can be repesented by 1c + 2d = $7.00, or c + 2d = $7.00
2 coffees and 3 donuts cost $12.00
This can be represented by 2c + 3d = $12.00
<u>So, the system is :</u>
c + 2d = $7.00
2c + 3d = $12.00
