Answer:
see the attached figure with letter to better understand the problem
we know that
If triangle ABC is similar to triangle PQR
then
the ratio of the corresponding sides are proportional
so
substitute the values
therefore
the answer is the option C
Step-by-step explanation:
find the square root of 323
sqrt(323) = 17.972
so 17 is one number now divide 323 by 17
323/17 = 19
17 x 19 = 323 so those are the 2 odd numbers
It is pretty long, hope you understand
x+y+z=6
+
2x-y+z=3
-------------
3x+2z=9
->3x=9-2z (1)
3x-z=0
3x=z (2)
From (1)+(2)-> z=9-2z
solve for z
-3z=9
z=-3 (3)
plug (3) in (2)
->3x=-3
->x=-1 (4)
Plug (3) and (4) in <span>x+y+z=6
</span>-3+y+(-3)=6
solve for y
y-6=6
->y=12
Answer:
x=-1
y=12
z=-3
At the start you will start with $7 and $7.60 there is a simple way and a more complex process. The simple way is using the formula of y=mx+b so y=.8x+7 and the other way is just too add .8 to 7 and .7 to 7.6 and keep doing that till you get the answer. The answer is 7, seven topping have to be added to make them the same price.
