3g-2x=-2135 x=2g+60 Solve for g

Mathematics
1 answer:
jarptica [38.1K]3 years ago
5 0

Answer:

x = -3970, g = 2015

Step-by-step explanation:

Solve this system of linear equations by substitution:  substitute 2g + 60 for x in the first equation.

Then we have:

3g - 2(2g + 60) = -2135

Performing the indicated multiplication, we get:

3g - 4g - 120 = -2135, or

     -g             =    -2015

Then g = 2015.  Then x = 2(-2015) + 60, or x = -3970

The solution is x = -3970, g = 2015

If I plan to run 400 yards and I have completed 80%, how many yards do I have left?
Dimas [21]

Answer:

You have 80 yards left to run.

Step-by-step explanation:

To solve this problem, we first must realize that if you have completed 80% of the run, that you have 20% left (this is because 100%-80% = 20%).  

Next, we must find 20% of 400 yards.  We must remember that in math, the word "of" represents multiplication.  We also know that 20% = 20/100 = 0.2.

To find 20% of 400 yards, we can perform the following operation:

20% * 400

0.2 * 400

80

Therefore, you have 80 yards left.

Hope this helps!
