You multiply 2 by the number of hours, 6.
2x6=12
answer is 12
Answer:
(0,-8)
x=0
y=-8
Step-by-step explanation:
There are a couple of ways you can solve this I used what I think is called the elimination method
We first start by writing the equations in linear form (y=mx+b)
For the first one we have -12x-5y=40
we add 5y to both sides and subtract 40 to get
-12x-40=5y
divide by 5 to get
-12/5x-8=y
Then the second one we have
12x-11y=88
same deal here, add 11y and subtract 88 to get
12x-88=11y
divide by 11 and get
12/11x-8=y
We then set the two equations equal to each other and get
-12/5x-8=12/11x-8
We can add 8 to both sides and get
-12/5x=12/11x
Just by looking at it you can see that the only solution for x is 0
Plug in 0 to the first equation and get -12*0-5y=40
This means that -5y=40
Solve for y and get -8
Answer:
5 < x
Step-by-step explanation:
first, we want to isolate x, so to get rid of the denominator of 2, we can multiply both sides by 2 to cancel it out
3(2) < 2(x/2) +1
6 < x + 1
now we subtract one from each side
6-1 < x +1 -1
5 < x
hope this helps!
Answer:
5.291e+12
Step-by-step explanation:
A. yes, because 4x5=20 so it is enough for her friends. B 4x2 = 8 (from 5.2) so Pamela has 0.8 string left
