Answer: 12. 5 km

Step-by-step explanation:

We have the following equation:

d=50 h

Where d is the distance in kilometers and h=0.25 h is the time in hours.

Solving the equation with the given data and conditions:

d=50 km/h(0.25 h)

d=12.5 km This is the traveled distance by th monster zip

1. Seven multiplied by three
7*3 the little star mean times

2. Twice the opposite of eleven= 2x+11
22 less than 3 times the number
3x-22
3x-22=2x+11
3x-2x=11+22
x= 33
So , it would be 2x+11 x is 33

Hope this helps good luck

Find the midpoint of the line segment joining the points ​(10​,7​) and ​(negative 2​,negative 7​).
Basile [38]

The midpoint of the line segment joining the points ​(10​,7​) and ​(negative 2​,negative 7​) is (4, 0)

<h3><u>Solution:</u></h3>

Given that line segment joining the points ​(10​,7​) and ​(negative 2​, negative 7​)

Thus the two points are ​(10​, 7​) and (-2, -7)

The midpoint of two points (x_1, y_1) and (x_2, y_2) is given as:

M(x, y)=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)

\text {Here } x_{1}=10 \text { and } y_{1}=7 \text { and } x_{2}=-2 \text { and } y_{2}=-7

Substituting the values in formula, we get

\begin{array}{l}{M(x, y)=\left(\frac{10+(-2)}{2}, \frac{7+(-7)}{2}\right)} \\\\ {M(x, y)=\left(\frac{10-2}{2}, \frac{7-7}{2}\right)} \\\\ {M(x, y)=(4,0)}\end{array}

Thus the midpoint of line segment is (4, 0)
