Who's is the solution set of the compound inequality 3.5x-10>-3 and 8x-9<39
velikii [3]
3.5x-10>-3  add 10 to both sides

3.5x>7  divide both sides by 3.5

x>2

... now for the other inequality:

8x-9<39  add 9 to both sides

8x<48  divide both sides by 3

x<6

So we have x>2 and x<6, so the compound inequality is:

2<x<6  and this means that the solution set is:

x=(2, 6)

Solve for x please for 10 points
Ira Lisetskai [31]

Answer:

\frac{x-2}{2+1}=\frac{4x-5}{3}

\frac{x-2}{3} =\frac{4x-5}{3}

3*\frac{x-2}{3} =\frac{4x-5}{3}*3

x-2=4x-5

x-2+5=4x-5+5

x-x+3=4x-x

3=3x

\frac{3}{3} =\frac{3x}{3}

1=x

andre [41]

Answer:

the runners have gone 20.8 times around the globe all together

Step-by-step explanation:

At the Bostom Marathon, we have a total of

N = 20,000 runners

We know that each runner ran a distance of

d = 26 miles

Therefore, the total distance travelled by all runners combined is:

D=Nd=(20,000)(26)=5.2\cdot 10^5 mi

We know that the circumference of the Earth is

c=2.5\cdot 10^4 mi

Here we want to find how many times around the globe would the marathon runners have gone. This can be found by calculating the following ratio:

n=\frac{D}{c}

And substituting the values, we find:

n=\frac{5.2\cdot 10^5}{2.5\cdot 10^4}=20.8

So, the runners have  gone 20.8 times around the globe all together.
