What is the solution to this system of equations?
mixas84 [53]

Answer:

(-2,4)

Step-by-step explanation:

The solution is the point at which the two lines intersect, (-2,4).  That point is the only one that satisfies (works) in both equations:

y = x + 6

4 = -2 + 6

and

y = -0.5x + 3

4 = -0.5(-2) + 3

4 = 1 + 3

====

You can also solve it algebraically:

y = x + 6

y = -0.5x + 3

-0.5x + 3 = x + 6   [Use the value of y from the second equation in the first equation]

-1.5x = 3

x = -2

Use this is y = -2 + 6:

y = 4

(-2,4)

Pedro spent 2 1/5 hours on his math homework and half as long on his science homework one weekend. If his English and social stu
Flura [38]

2 1/5 hours on homework for math = 2.2

Science homework took 1.1 hours to complete.

2.2+1.1= 3.3

7/8 of an hour is 50 minutes because we know that an hour is 60 minutes and every 10 minutes is a number for the numerator, if that makes sense.

3.3 of an hour plus 50 minutes, would equal 3.8 since the 3 after the point would be minutes. To convert into hours, since an hour is 60 minutes, we have 4 hours and 20 minutes he spent on homework over the weekend. That would be your answer! Hope this helped.
