Answer:

The value of x is -29/11

Step-by-step explanation:

7(5x + 12) = 2x - 3

35x + 84 = 2x - 3

Now, Subtract 84 from both side we get,

35x + 84 - 84 = 2x - 3 - 84

35x = 2x - 87

Now, Subtract 2x from both side we get,

35x - 2x = 2x - 2x - 87

33x = - 87

Then, divide both side by 33 we get,

33x/33 = - 87/33

x = - 29/11

Thus, The value of x is -29/11

Answer:

x=29/11

Step-by-step explanation:

7(5x+12)=2x-3

=35x+84=2x-3

=35x-2x=-3-84

=33x=-87

then divide both side by 33

notka56 [123]

Answer:

Average speed is 48 km per hour

Step-by-step explanation:

A student drove to the university from her home and noted that the odometer reading of her car increased by 16.0 km. The trip took 20.0 min. (a) What was her average speed? in km/hr

Distance traveled is 16 km and the time taken is 20 minutes

convert minutes into hour. to convert minutes into hour we divide by 60 because 1 hour = 60 minutes

\frac{20}{60} =\frac{1}{3}

so time = 1/3  and distance = 16

Average speed = distance by time

speed =\frac{16}{\frac{1}{3} } =\frac{48}{1}= 48

Average speed is 48 km per hour

The points R(−4, −1) and S(2, −5) are two vertices of right triangle RST. The hypotenuse of the triangle is RS.
Norma-Jean [14]
      If RS is the hypotenuse of the triangle RST and point T is in Quadrant 3, then point T must be the intersection of the lines: x = - 4 and y = - 5.
       Therefore, the coordinates of point T are ( x, y ) = ( - 4, - 5 ) 
       Answer:
       T ( - 4, - 5 )
