$\frac{1}{16} = 64^{4x-3} ,
 \frac{1}{4^2} =( (4)^3)^{4x-3},
 4^{-2} =(4)^{3(4x-3)},
-2=3(4x-3)

Answer:

1. 2/5

Step-by-step explanation:

When it says the ratio is 5 to 2, that means 5 is always first:

5 : 2 is correct

5/2 is correct

10 : 4 is correct (multiplied 2 on both sides)

2/5 is incorrect because 2 is first. That means that this ratio would be 2 to 5, not 5 to 2.

36/2=18
18/14+c +18/14-c=2.8
18(14-c)+18(14+c)=2.8(196-c²)
504=548.8-2.8c²
2.8c²=44.8
c²=16
c=±4
