Answer:

$x>-5$

Step-by-step explanation:

$\frac{-1}{5} x+1$

Subtract 1 from both sides

$\frac{-1}{5} x+1-1$

Simplify

$\frac{-1}{5} x$

Multiply both sides by -1, which reverses the inequality also

$\frac{-1}{5} x(-1)>1(-1)$

Simplify

$\frac{1}{5} x>-1$

Multiply both sides by 5

$5*\frac{1}{5} x>5(-1)$

Simplify

$x>-5$

Sanjit drives the 45 km distance between York and Leeds he then drives a further 42 km from Leeds to Blackpool

I am Lyosha [343]

Answer: His average speed for his total journey from York to Blackpool is approximately 61.41 km/h.

Step-by-step explanation:

$\text{ The average speed}=\frac{\text{Total distance covered}}{\text{Total time taken}}$

Since, The distance covered by him from York to Leeds = 45 km,

The speed when he covered this distance = 54 km/ h

Thus, the time taken by him in travelling from York to Leeds = 45/54 hours (Because, Time = Distance/speed)

Now, The distance covered by him from Leeds to Blackpool = 42 km,

The time taken by him in travelling from Leeds to Blackpool = 35 minutes = 35/60 hours

Hence, the total time taken by him in this journey

$=\frac{45}{54}+\frac{35}{60}=\frac{450+315}{540}=\frac{765}{540}=\frac{17}{12}$ hours

And, the total distance he covered= 45 + 42 = 87 km

Thus, His average speed

$=\frac{87}{17/12}= \frac{12\times 87}{17}=\frac{1044}{17}=61.4117647\approx 61.41\text{ km per hour}$

HELP PLEASE AND WORTH 20 POINTS

Inessa05 [86]

If the distance is 1.5 from -2, then it could be 1.5 less than -2 or 1.5 more than -2, so we know that we will have two points on the number line.
Let’s first find 1.5 less than -2
We will subtract 1.5 from -2
-2-1.5 = -3.5
Our first value of n will be -3.5
Next let’s find 1.5 more than -2
We will add 1.5 to -2
-2+1.5 = -0.5
Our second value of n will be -0.5

Our answers will be -3.5 and -0.5
