Answer:
15 hours
Step-by-step explanation:
2x + y = 8
x + 3y = -6
Note: This is the process of elimination
First: Multiply one side by -3 to get rid of your y's.
It should look like:
-3 ( 2x + y) = 8 (-3)
Then it should look like:
-6x - 3y = -24
x + 3y = -6
Go ahead: Get rid of the y's
Your equation should then look like:
-6x = -24
x = -6
Next: You would add x to -6x and subtract -6 from -24.
It should look like:
-5x = -30
Finally: You would get your x alone and divide both sides of your equal sign by -5.
Remember: Negative and a negative makes a positive.
Your answer should be:
x = 6

Answer:
Step-by-step explanation:
4x(3x-7)-19x2
4x*3x=12x
-7*-19 = 133 * 2 = 266
12x + 266
Don't Trust This I suck at math, but I am confident that is the answer. It's either that or this: 12x-52. Trust me if you want. But I am warning you.
Answer:
8 Newtons
Step-by-step explanation:
Friction and Gravity are both known to be negative forces such as -20 and -14
So doing the math
22 + 20 = 42
42 - 20 = 22
22 - 14 = 8
8 is your answer, hope this helped!
