Dave uses the associative property of multiplication ro write an expression that is equivalent to 8×(5×b) which expression did he write a. 8b×5b

b. (5+b)×8

c. 8+(b×5)

e. (8×5)×b

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
