Answer:
y = x*(6 feet/1 fathom)
Step-by-step explanation:
We know the relation:
1 fathom = 6 feet.
We can write:
1 = (6 feet/1 fathom)
Now, remember that any number multiplied by 1 does not change.
Then suppose that we have a measure of 3 fathoms, then:
3 fathoms = (3 fathoms)*1
= (3 fathoms)*((6 feet/1 fathom)) = (3 fathoms/1 fathom)*(6feet)
= 3*(6 feet) = 18 feet.
So we changed the units by multiplying the original measure by (6 feet/1 fathom)
Then, if x is the depth of water in fathoms and y is the depth of the water in feet, we can write:
y = x*(6 feet/1 fathom)
The answer is B B B B B B B B B B
1. y=6
2. y=3/2 alternate form y=1 1/2, y=1.5
2. 3. and 4. the same answer
Step-by-step explanation:
don't forget to rate
So our equation to find this can be represented by 7x + 10 = 45.
(x representing miles run)
Just solve for x!
Subtract the 10 from both sides, you've got
7x = 35
And now to isolate the x, we divide both sides by 7.
Now we're left with just
x = 5!
We can check this by substituting 5 as x in our equation.
7x x 5 + 10 = 45
45 = 45
It's right!
So the runner ran 5 miles total.
Hope this helps!
If I skimmed over this too much, let me know and I'll try to explain the best that I can.
