Theophilus had a bag of toffees that he wanted share with all of his best friends.
Because Theophilus had a huge number of best friends, and because he was
concerned for their dental dental health, he began by cutting each toffee into
smaller pieces before passing them out.
He began with 6 toffees in the bag. Each toffee was 3-inches long, and he cut
each piece into 1-inch pieces.
To how many friends was he then ready to hand a chunk of toffee ?
Answer:
9
Step-by-step explanation:
PEMDAS IS
parentheses
Exponents
Multiply and divide
Addition and subtraction
First you start with the parentheses so
1 + 2 = 3
Now you have 6/2 x 3
Multiply and divide means you either divide or multiply what ever comes first going left to right
So
6/2 = 3
3 x 3 = 9
If it was reversed we’d have
2 x 3/6 which would be
6/6 = 1
Lets say the number is x so we can make an equation
If is at least 21, that means it has to be greater then or equal to it.
6+5*x>=21
You can subtract 6 from both sides
5*x>=15
Then divide both sides by 5
x>=3
You can conclude that the number is greater then or equal to 3.
14 because he didn't gather 28 or more he gathered only 14
Answer:
7x+1 ≤12
Step-by-step explanation:
The common letter used to represent a variable is x. Thus, a 7 is added to it to signify that it is being multiplied. Then, increased by one means +1. At most is a fancy word for less than or equal to ( ≤).
