This is solved and the answer to your question! Hop this helped!
We can convert 20km to 20,000m. Then, we can subtract 800m (walking distance) from 20,000m which would result in 19,200m. Then we can put 19,200m and 20,000m as a fraction (19200/20000). Before we can multiply it by 100 to make it in the percentage form, we can get rid of 2 zeroes for both number making it 192/200 and then further simplifying it to 24/25 by dividing both numbers by 8. Finally to get the percentage we can multiply 24 and 100 (2400) and then divide the result (2400) by 25. The final answer is 2400/25=96 meaning he cycled 96% of the journey and walked 4% of the journey (100-96=4).
To find the solution to this, we need to use the substitution method.
y = -5x + 3
Substitute the value for y.
y =1
1 = -5x + 3
Now, solve for x.
1-3 = -5x + 3 Apply the inverse operation to both sides of the equation.
-3
1-3 is -2
-2 = -5x
-5x/-5 = -2/-5
x = 0.4
Final answer:- x = 0.4 y = 1
Answer:
No Solution
Step-by-step explanation:
When the simultaneous equation is solved, we get an answer of 0 = -9. This statement is false. So there are no solutions.
Answer:
100
Step-by-step explanation:
x / 5 = 20
Cross multiply,
x = 20 * 5
x = 100
