Answer:

-6

Step-by-step explanation:

First, subtract 20 from both sides: $m < -12=2x$

D=rtthe distances are not equal, but they add up to a total of 400 milesone bus goes 55mph times t so that is 55t (that represents the distance in one direction)the other bus goes 45 mph,so that is 45t (that represents the distance in the other direction)the total distance is 400, so the equation is distance one direction + distance the other direction = 400your equation is 55t + 45t = 400 100t = 400 t= 4 hoursso after 4 hours they will be 400 miles apart

Two angles are supplementary if their sum is 180 degrees. One angle measures three times the measure of a smaller angle. If X re

Mkey [24]

So 3 times the measure of a small angle

3x + x= 180

4x = 180
X= 45

3(45) + 4(45) = 180

Hope this helps!

Four cookies and three cupcakes code $13.25. Five cookies and two cupcakes cost $11.75. Give the system of equations that could

Kaylis [27]

Answer:

cookie: $1.25
cupcake: $2.75

Step-by-step explanation:

Let x and y represent the cost of a cookie and a cupcake, respectively.

4x +3y = 13.25

5x +2y = 11.75 . . . . . . the system of equations

___

By Cramer's rule:

x = (3(11.75) -2(13.25))/(3(5) -2(4)) = 8.75/7 = 1.25

y = (13.25(5) -11.75(4))/7 = 19.25/7 = 2.75

The cost of one cookie is $1.25; the cost of one cupcake is $2.75.
