Answer:

m=-30

Step-by-step explanation:

5m+100=2m+10

We want to get the variable on one side of the equation. First we subtract 100 from both sides.

5m=2m-90

Subtract 2m from both sides.

3m=-90

Divide both sides by 3.

m=-30

Find the points which divide the line segment joining the points (0, -3) and (7,1) in the ratio 2:3

rewona [7]

Answer:

Known two points, list function expression, use

$y-y_{0}=k(x-x_{0})$

$k= \frac{y_{2} -y_{1\\}}{x_{2} -x_{1} }$

The function expression is

$y=\frac{4}{7}x-3$

It is known that the cross section of two points is 7, so the point of 2:3 is 14 / 5, that is, 0 + 14 / 5 is the abscissa of the point, which is substituted into the original equation to get y = - 7 / 5.

So the result is $(\frac{14}{5} ,-\frac{7}{5} )$

Harley is riding her bicycle 9.88 miles from her house to work. If she rides at a speed of 13 miles per hour, how long will it t

PIT_PIT [208]

It would take Harley 46 minutes to arrive at work.

Step-by-step explanation:

Given,

Distance from house to work = 9.88 miles

Speed of bicycle = 13 mph

Distance = Speed*Time

Time = $\frac{Distance}{Speed}$

Time = $\frac{9.88}{13}$

Time = 0.76 hour

We know that 1 hour = 60 minutes

0.7 hours = 60*0.76

0.7 hours = 45.6 minutes

Rounding off to nearest whole minute

0.7 hour = 46 minutes

It would take Harley 46 minutes to arrive at work.

Answer:

Assuming that the line is completely horizontal, that the 1 at the top is indicating the question number, and that the 3 is the only other piece of information given about the line, I think it's y = 3. I hope this is right, sorry because that's a terrible question. Good luck!
