Which two expressions are equivalent to 8(6x + 9)

Mathematics

<h3>Answers:   Choice A and Choice E </h3>

Explanation:

The distributive property allows us to go from the original expression to choice A. We multiply the outer term 8 by each term inside the parenthesis.

In general, the distributive property is a(b+c) = ab+ac. Example: 2(3+4) = 2(3)+2(4) = 6+8 = 14.

After simplifying the expression in choice A, it leads directly to choice E. This is because 8(6x) = 48x and 8(9) = 72.

Side note: A common mistake students do is to multiply the outer term by only one of the terms inside the parenthesis, while forgetting about the other term inside. Choice B shows this mistake. It's possible your teacher put choice B in there as a trap/trick answer.

The number of sweets s that each friend gets is the number of sweets in a box n divided by the number of friends f the sweets ar
Ainat [17]

Answer:

The number of sweets each friend gets = 5

Step-by-step explanation:

The number of sweets s that each friend gets = the number of sweets in a box n ÷ number of friends f the sweets are shared between

s = n ÷ f

s = n/ f

if there are 60 sweets and 12 friends.

That is,

n = 60 sweets

f = 12 friends

Find s,

s = n/ f

= 60 / 12

= 5

s = 5 sweets

The number of sweets each friend gets = 5

Tito solved this equation. 2(3x+5)=22+5x-3x.
Lelechka [254]

Hello from MrBillDoesMath!

Answer:

x = 3

Discussion:

Remark: if Tito solved the equation why didn't he tell you what the solution was ?  );   Guess I'll have to do it myself....

2(3x+5) = 22 + 5x - 3x                 => 2(3x+5) = 6x + 10 and 5x-3x = 2x

6x + 10 = 22 + 2x                         => subtract 2x for both sides

6x - 2x + 10 = 22                          => subtract 10 from both sides

4x = 22-10 = 12                             => divide both sides by 4

x = 12/4 =3

Thank you,

MrB
