Answer:missing angle = 42, x=10

Step-by-step explanation: to find the missing angle, we need to subtract 48 from 90, because it is a right angle. 90-48=42.


therefore, 3x+12=42

3x=42-12

3x=30

X=30/3

x=10

Henry ran five races, each of which was a different positive integer number of
dolphi86 [110]

Answer:

10 miles.

Step-by-step explanation:

Let x be the number of miles on Henry's longest race.

We have been given that Henry ran five races, each of which was a different positive integer number of  miles.

We can set an equation for the average of races as:

\frac{\text{The sum distances of 5 races}}{5}=4

As distance covered in each race is a different positive integer, so let his first four races be 1, 2, 3, 4.

Now let us substitute the distances of 5 races as:

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

\frac{10+x}{5}=4

Let us multiply both sides of our equation by 5.

\frac{10+x}{5}*5=4*5

10+x=20

Let us subtract 10 from both sides of our equation.

10-10+x=20-10

x=10

Therefore, the maximum possible distance of Henry's longest race is 10 miles.

Graph the line with slope <br> 2<br> 5<br><br> and <br> y<br><br> -intercept <br> −<br> 7<br><br> .
tia_tia [17]

Answer:

See attachment

Step-by-step explanation:

We want to graph the line with slope

m =  \frac{2}{5}

and y-intercept ,

b =  - 7

The equation of this line is

y =  \frac{2}{5}x - 7

Starting at -7 on the y-axis, we run 5 units and rise 2 units right.

Then draw a line through the y intercept and the new point

The graph is shown in the attachment.
