Answer:
5/9
Step-by-step explanation:
let other fraction be x
x+1/3=8/9
x=8/9-1/3
x=(8-1*3)/9
x=(8-3)/9
x=5/9
<h3>
Answer: x = -3/k</h3>
==============================================
Work Shown:
kx+7 = 4
kx+7-7 = 4-7 .... subtract 7 from both sides
kx = -3
kx/k = -3/k .... divide both sides by k
x = -3/k
The value of k cannot be zero. As the steps show, we are following PEMDAS in reverse to undo each operation to help isolate x. Subtraction is the opposite of addition, and division is the opposite of multiplication.
Answer:
10 km in 97 seconds, 8 km in 83 seconds, 18 km in 198 seconds, 15 km in 168 seconds.
Step-by-step explanation:
The unit rate for each session can be found by dividing the kilometers by the seconds. Then, make an equivalent fraction by dividing both the numerator and denominator by the numerator. This will show how many seconds it took to finish 1 kilometer during that session.
