Choice
<span>4(b-6)+19
Easily you would better start with distributing 4 to the brackets
4(b -6) = 4*b - 4*6 = 4b - 24
then add 19 to these terms, we get:
4b - 24 + 19
combine like terms (which are -24 + 19), we get:
4b - 5
That's it....

Answer:
4 7/8
Step-by-step explanation:
3 1/4 / 2/3
convert mixed numbers to improper fractions: 3 1/4 / 2/3
13/4 / 2/3
apply the fraction rule: a/b / c/d = a/b * d/c
= 13/4 * 3/2
multiply fractions: a/b * c/d = (a * c)/(b * d)
= (13 * 3)/(4 * 2)
multiply the numbers: 13 * 3 = 39
= 39/(4 * 2)
multiply the numbers: 4 * 2 = 8
= 39/8
convert improper fractions to mixed numbers: 39/8 = 4 7/8
= 4 7/8
