$52 because 15% of 40 is 6 but you have to add it twice so 40 + 6 + 6 = 52. Hope i helped!
Answer:
x = 8
y = 1
Step-by-step explanation:
First you want to substitute y in for 1 to get
2x + 4 = 20
Then subtract four to both sides to get
2x = 16
Then divide 2 by 16 to get
x = 8
and then plug the 8 into the original equation
2(8) + 4y = 20
And then solve for y!
Answer with explanation:
Relation between Speed , Distance and time
Distance =Speed × Time
→It means Speed is inversely Proportional to time.
As distance will remain constant , in that frame of reference
If speed of light in a Medium
Then, time taken to cross the medium = t seconds or hours or another unit of time.
Now, If speed of light is 50% of the speed of light relative to us
That is Speed of light in another medium
Then, time taken to cross the medium = 2t seconds or hours or another unit of time.
Using Unitary Method
Answer:
8.9
Step-by-step explanation:
Let X be the actual dimension for the Length
The ratio is 2/43
2/43 = x/129,
43x = 384,
x= 384/43,
<u><em>~8.9</em></u>
It should be 16, but because there is only 2 examples, I'm not totally sure. But, I hope this helps you! :)
