Answer:
-0.4-4y
Step-by-step explanation:
-0.5(0.8+8y)
Distribute -0.5 into the parentheses
= -0.5×0.8+(-0.5)×8y
= -0.4+(-4y)
A negative and a positive make a negative
= -0.4-4y

18 and 72
the smaller part can be assigned as x while the larger will be 4x. Both numbers need to add up to 90, giving the equation: 4x+x = 90
Solve:
4x+x = 90
5x = 90
x = 18
4x = 72
