If a = 0.5, b = -6, c= -0.2, and d = 3 evaluate the following.
b.
d - b
a.
bc
-
2ac
d.
d
C.
ab2
e.
dc + a
f.
ab
d

Answer 1

Explanation:

`a=0.5`
`c=-0.2`

`b=-6`
`d=3`

All we need to do is substitute:-

a)
`bc=\left(-6\right)\left(-0.2\right)=\boxed{1.2}`

b)
`d-b=3-\left(-6\right)=\boxed{9}`

c)
`2ab=2* \:0.5\left(-6\right)=\boxed{-6}`

d)
`ab^2=0.5\left(-6\right)^2=\boxed{18}`

e)
`dc+a=3\left(-0.2\right)+0.5=\boxed{-0.1}`

f)
`(ab)/(d) =(0.5\left(-6\right))/(3)=\boxed{-1}`
