Answer:
x > 6.5
Step-by-step explanation:
Let's temporarily replace the inequality sign ">" with "=".
This gives us: 5x - 2 = 3x + 11.
If we subtract 3x from both sides we are left with:
2x - 2 = 11.
If we add 2 to both sides, we are left with:
2x = 13.
If we divide both sides by 2, we are left with
x = 6.5.
Now let's substitute back in the inequality sign
x > 6.5
Hope this helps!!!! :)
Step-by-step explanation:
you need to substitute the x in (7x +2y=13) with (x=2y+11) to solve it
Answer: 65
Step-by-step explanation:
We know that her three tests are 69,65,77 so far
in order to get her average at 69 we need to do the following:
69+65+77+x=(69x4)
211+x=276
x=276-211=65
if she will get a 65 her average will be 69
Set up the equation like 4b+61=0, subtract 61 from both sides, and that'll be 4b=-61. Divide both sides by 4. b=15.25
