We can solve this using substitution.
because x-y=2.5
x=y+2.5
Now substitute x into other equation.
2(y+2.5)^2-2y=125
2y^2+10y+12.5-2y=125
2y^2+8y-112.5=0
Now comes the ugly part
y=-4+-sqrt(16+900)
y=-4+-sqrt916
y=-4+-2sqrt229
x=-1.5+-2sqrt229
Here, you have to foil the equation.
Distribute 4x to all sides, then distribute the -3 to all sides. Next, combine like terms. If you do this, your answer will be
11. brother = ???
???- 12 = 14
14+12=26
brother is 26.
12. 21.35 - 8.95 = 12.4
cost of colored pencils = $12.40
13. 37- 8 = 29
14. $95 - $73 = $22
The answer is D. decimal number of percentage
Answer:
yes
Step-by-step explanation:
well converse is
If q, then p
and inverse is
If no p, then not q
butttttt lets put this in human terms
If I am allergic to donuts, then I don't like to eat donuts.
and the inverse is
If I don't like to eat donuts, then I am allergic to donuts.
It is true no matter what! However, there could also be other reasons you don't liek donuts but nonthless this is one true reason that exists bc converse.
