Answer:x=1 y=2
Step-by-step explanation:
you add and get 8x=8 x=1 so plugging in one you get 5+2y=9 so 4=2y so y=2
Let:
Lala be l
Polina be P
Goffy be G
the respective ratio is 6:5:3
Given that Polina's loudness is 420 decibels then the total loudness will be calculated as follows:
Total ratio=6+5+3=14
hence total loudness will be:
14/5×420
=1,176 decibels
It would be: 255 - (255 * 22%)
= 255 - (255 * 0.22)
= 255 - 56.1
= 198.9
In short, Decrease in Price is $56.1 & Sale Price is $198.9
Hope this helps!
Parallel lines have the same gradient.
The equations are either in the form y = mx+b (m is the gradient)
or in general form ax + by + c = 0 (-a/b)
The gradient of y = 2x - 4 is 2.
The answer is B (gradient = -4/-2 = 2)
