1 5/15
Step-by-step explanation:
Answer:
(23, 4)
Step-by-step explanation:
If we use substitution, we need to rewrite the 2nd equation so we can substitute it into the first.
Step 1: Rewrite 2nd equation
x = 5y + 3
Step 2: Substitution
2(5y + 3) - 5y = 26
Step 3: Distribute
10y + 6 - 5y = 26
Step 4: Combine like terms
5y + 6 = 26
Step 5: Isolate <em>y</em>
5y = 20
y = 4
Step 6: Find <em>x</em>
x - 5(4) = 3
x - 20 = 3
x = 23
And we have our final answer!
Answer:
21:50
Step-by-step explanation:
We need to find the ratio of 420 m to 1 km.
We know that,
1 km = 1000 m
So,
The ratio becomes,
So, the required ratio is 21:50.
Answer:
Same-side exterior angles
Step-by-step explanation:
Through the process of elimination it is not:
→ Corresponding angles as that would be 2 and 6
→ Same side interior angles as that would be 3 and 6 or 4 and 5
→ Alternate interior angles as that would be 6 and 4 of 3 and 5
For this case the first thing you should know is that we have the following definition:
V = I * R
Where,
V: voltage
I: current
R: resistance
Therefore, by clearing the Resistance we have:
R = V / I
Substituting the values:
R = 12/48
R = 1/4 ohms
Answer:
The value of the resistance is:
R = 1/4 ohms
