Hello, Tennant17!

The model for direct variation is y=kx where k is a constant. 
In this case, y is m and x is t.
So the equation is m=kt
Plug in the values of m and t to find k.

19= k * 2
Solve for k
k= 19/2
k= 9.5

Plug k back into the equation.

m=9.5t

So the answer is:
B. m=9.5t

Hope this helps :)

Triangle ABC has a side measuring 7 inches, a side measuring 10 inches, and an angle measuring 38°. To construct another triangl
ki77a [65]
The complete question gives the following options:
A) The 7-inch side and the 10-inch side must make a 52° angle.
B) The 7-inch side and the 10-inch side must make the 38° angle.
C) It does not matter whether or not the 7-inch side and the 10-inch side make a 52° angle.
<span> D) It does not matter whether or not the 7-inch side and the 10-inch side make the 38° angle. 

According to the SAS rule for triangle congruency, two triangles are congruent if they have congruent two sides and the angle included.

Therefore, the only way to build a triangle congruent to ABC is to say that the given angle is the one included between the two sides.
Therefore, the correct answer is: </span><span>B) The 7-inch side and the 10-inch side must make the 38° angle.  </span>

X + 15y = 40 / x + 10y = 30 solve for x and y
Elina [12.6K]
Use elimination to find both values.
Subtract the second equation from the first equation
x + 15y = 40
- x + 10y = 30
————————
5y = 10
y = 2

Plug in the value for y into one of the equations. I’m going to put it in the second equation.
x + 10(2) = 30
x + 20 = 30
x = 10

x = 10
y = 2
