-1.5

By using a calculator, making the mixed numeral 3 3/4=3.75, and making -2/5 a decimal = -0.4, you can now simply multiply:

3.75 x -0.4= -1.5
Remember that a positive and a negative give you a negative answer.

The plane flies 725 miles per hour. how many minutes will it take to fly 150 miles
ioda

Answer:

12.41 minutes.

Step-by-step explanation:

It is given in the question that a plane can fly 725 miles per hour.

So, the plane goes 725 miles in 1 hour i.e. 60 minutes.

Now, we have to find the time the plane takes to fly 150 miles.

As the plane is flying at a constant rate, so we can use the unitary method to get the required time.

Therefore, the plane will take \frac{60 \times 150}{725} = 12.41 minutes to fly 150 miles. (Answer)

M= -2 b=15 write the equation of the line​
NeTakaya

Answer:

y=-2x+15

Step-by-step explanation:

Hi there!

We are given that m=-2, b=15, and we want to write the equation of the line, given these values

We can write the line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, since we are given the values of both m and b.

Since we know the values of m and b (-2 and 15 respectively), we can substitute those numbers in as the variables they equal to.

Substitute -2 as m:

y=-2x+b

Substitute 15 as b:

y=-2x+15

Hope this helps!
