Question

Evaluate 4-0.25g+0.5h when g=10 and h=5

Answer 1

4

Explanation:

`4-0.25g+0.5h\\g =10\\h=5\\\\4 -0.25(10)+0.5(5)\\\\\mathrm{Remove\:parentheses}:\quad \left(a\right)=a\\=4-0.25*\:10+0.5*\:5\\\\\mathrm{Multiply\:the\:numbers:}\:0.25*\:10=2.5\\=4-2.5+5*\:0.5\\\\\mathrm{Multiply\:the\:numbers:}\:0.5*\:5=2.5\\=4-2.5+2.5\\\\\mathrm{Add/Subtract\:the\:numbers:}\:4-2.5+2.5\\=4`

Answer 2

`4`

Explanation:

`4 - 0.25g + 0.5h = 4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 1.5 + 2.5 = 4`
