Question

For questions 4–5, simplify the expression.

24h + 3d – 10h + 8d

A. 14h + 11d
B. 14h – 5d
C. 25hd

12s + 4 + 4s – 2
A. 18s
B. 2(8s + 3)
C. 2(8s + 1)*

Answer 1

1.
`\mathrm{Group\:like\:terms} \ \textgreater \ 24h-10h+3d+8d`


`\mathrm{Add\:similar\:elements:}\:24h-10h=14h \ \textgreater \ 14h+3d+8d`


`\mathrm{Add\:similar\:elements:}\:3d+8d=11d \ \textgreater \ 14h+11d`

2.
`\mathrm{Group\:like\:terms} \ \textgreater \ 12s+4s-2+4`


`\mathrm{Add\:similar\:elements:}\:12s+4s=16s \ \textgreater \ 16s-2+4`


`\mathrm{Add/Subtract\:the\:numbers:}\:-2+4=2 \ \textgreater \ 16s+2`

Hope this helps!
