Question

Can You Express this?​

Answer 1

Answer:

Step-by-step explanation:

1.a) x=8 y=10 therefore 5x/2y = 40/20 = 2

b) x = 1/2 y = 2/3 therefore 5x/2y= 2.5/0.66

2. a) a=4 b=3 c=2 therefore ab3/c = 1728/2

b) a=-2 b=-2 c = 2 therefore ab3/c = 4/2 = 2

3. a) e=11 f=7 therefore e+5/4f-4 = 16/24= 2/3

b) e = -1 f = -4 therefore e+5/4f-4 = 4/-20
