Answer: Yes, it is a right triangle
Step-by-step explanation:
Use the pythagorean theorem in order to determine whether this triangle is a right triangle. Plug in the values given in the problem (4, 7.5, and 8.5) into this equation (a^2+b^2=c^2). This gives you 4^2+7.5^2=8.5^2, and this equation is valid because 4^2+7.5^2 does equal 8.5^2.
2x-3=-4x+-9
2x-3=-4x-9
negative number and positive number= negative number
2x-3=-4x-9
2x+4x-3=-4x+4x-9
6x-3=-9
6x-3+3=-9+3
6x=-6
Divide by 6
6x/6=-6/6
x=-1
Check answer by using substitution method
2(-1)-3=-4(-1)+-9
-5=-4-9
-5=-5
Answer is x=-1
firts lets see how many dollars she has
192 divided by 4 is 48 so she currently has 48 dollars.
and she puts in 2 quarters daily
so lets see how much she need to earn
75 - 48 is 27
lets see how many quarters she need to have 27 dollars 27 x 4 is 180
now lets divide 180 by two because shes giving two everyday. 180 divided by 2 is 54 so if she kept adding two quarters everyday it would take her 54 days to get the rest of the money she need to by and iPod.
i dont know if this helped or not but i solved it
Let me think if you look and multiply all to like 20 the answer is 3 it is
