5/12 - 4/5 = -23/60. You can't simplify -23/60. Hope this is right
Answer:
-6x-9y is the answer
Set up a proportion:
kid/dad = kid/dad
8/9 = 5.5/dad
Cross multiply to solve proportions:
8*dad = 9*5.5
8*dad = 49.5
dad = 6.1875 feet
They want inches so multiply by 12:
74.25 inches
They want "nearest inch" so:
Dad is 74 inches tall.
g(x)=3x-5
g(-4)=3(-4)-5
g(-4)=(-12)-5
g(-4)=(-17)
