<em>Writing 6(3x + 8) + 32 + 12x in 3 different ways:</em>
∵ 6(3x + 8) = 18x +48 as distribute law suggests that a(b + c) = ab + ac
- w₂ = 18x + 80 + 12x ∵ 48 + 32 = 80
- w₂ = 30x + 80 ∵ 18x + 12x = 30x
Step-by-step explanation:
As the expression is 6(3x + 8) + 32 + 12x, and we have to write it in three different ways. Using the properties of operations we can write it in three different ways,
Let way one be denoted as w₁
Let way two be denoted as w₂
Let way three be denoted as w₃
So, lets write 6(3x + 8) + 32 + 12x in 3 different ways:
∵ 6(3x + 8) = 18x +48 as distribute law suggests that a(b + c) = ab + ac
- w₂ = 18x + 80 + 12x ∵ 48 + 32 = 80
- w₂ = 30x + 80 ∵ 18x + 12x = 30x

Answer:
20
Step-by-step explanation:
If 36 boys can conplete a task in 4 hours, then 19.35 boys could do it in 2 and a fourth hours.
You can set up an equation
A fourth of an hour is 15 minutes, so,
36 is to 4 as x is to 2.15, or,
36=4 as X=2.15
Multiply 2.15 by 36 (77.4)
77.4 divided by 4= 19.35.
Of course, you cannot have 19.35 boys, so there must be 20.
Hope this helps!
