Answer:
x = -25/3
Step-by-step explanation:
Start with the given equation: (-3/5)x + 2 = 7.
We must isolate x. Here we have 2 added to (-3/5)x; the inverse operation would be subtraction of 2 from both sides. This results in:
(-3/5)x = 5.
Now, in (-3/5)x, we have division by 5. The inverse of division is multiplication. So, we multiply both sides of (-3/5)x = 5 by 5, obtaining
-3x = 25.
We want x alone. Here x has been mult. by -3. The inverse op. would be division of -3x = 25 by -3.
Performing this division, we get x = -25/3.
Dustin has completed more problems.
You can first use the 2 factors of 24, which are 3 and 8. To make it so you can compare the amount of problems completed with total amount, you need to multiple 8 x 3 and 3 x 3. This will turn 3/8 into 9/24, meaning that dustin has completed 9 problems. You can first use the 2 factors of 30, which are 2 and 15. Once again, to make it so you can compare the amount of problems completed with total amount, you need to multiple 2 x 15 and 2 x 4. This will turn 4/15 into 8/30, meaning that kelsey has completed 8 problems.
If you didn't go in a straight line, you will not reach 30 miles but however 30 miles, in general, going at a pace of 75mph it would take you 1 through 1 hour and a half.
