Answer:
Torrance spends 16$ on his brother
Step-by-step explanation:
You have 100$
So, we have
x (brother) + x (sister) + x (mother) = 100
But, since 10$ less will be spent on the sister than the brother, it becomes (x - 10) and twice + 6$ is spent on the mom, it also becomes (2x + 6)
Our equation then becomes
(x - 10) + x + (2x + 6) = 100
X will end up equaling 26. This is how much is spent on the sister.
(x - 10) will be substituted for (26 - 10), which equals 16.
I'm not sure if this is right so you might want to check with somebody (since I may be wrong) I hope this helps you understand how to basically do it though. <3
Answer:
(x+6)*3
Step-by-step explanation:
You will need to do this equation simply; and in order for that matter.
So you need to use the brackets so you know what comes first.
Remember BIDMAS or BODMAS
BIDMAS: BODMAS:
Brackets Brackets
Indices Order --- (These mean the same thing)
Divide Divide
Multiply Multiply
Addition Addition
Subtraction Subtraction
As you can see the brackets come first, so you do what is INSIDE the brackets before anything. (x+6)
To finish, you will need to multiply, but as it is an unknown, you don't know what to multiply the 3 by.
<u>So x, add 6, then times by 3 = (x+6) *3</u>
