1 answer:

7 0

If you're talking x in particular, it can't be isolated. See, if we have this equation, x=5, we divide the Answer by the Answer, so 5/5=1. We divide the Answer by x, so x would appear x/5. So, x/5=1

a train goes 20% farther than an older train in the same amount of time. During the time it takes the other train to go 200 mile

MakcuM [25]

Answer:

240 miles

Step-by-step explanation:

To solve this we need to write an equation. For this problem let d be the distance traveled. We know that the new train (being much more modern than poor old Thomas who is long retired) can go 20% further. To show this we will take 20% of 200 and then add that to the original distance.

Our equation would look something like this:

d=200+(20%·200)

[one more little note: to find percentage take your percent and convert it into a decimal 20%=0.2)

d=200+(0.2·200)

d=200+40

d=240

What is the solution to the inequality? -2x-4 less than or equal to 11

Rashid [163]

Answer:

x ≤ $\frac{-15}{2}$

Step-by-step explanation:

So first you would start by getting rid of the -4. To get rid of -4, you would need to + 4 on each side leaving you with -2x ≤ 15. Now you need to get rid of -2 from x so that would convert equation to x ≤ $\frac{-15}{2}$ . Hoped it helped!
