Hello,
<u>Set up a proportion</u> :
7 → 21
100 → ?
<u>Cross multiply</u> :
100 * 21 / 7 = 300 students
Bye :)
I don’t understand the equation. What am I solving for?
Answer:
24F is a increase I belive and 39F is a decrease
A. £549 376 / 4 = £137344 per word
B. £549 376 / 16 = £34336 per letter
C. £549 376 / 37 = £14848 per letter
D. £549 376 / 512 = £ 1073
If you want to use integer tiles to find the product of 2(-5), think of it as you having 2 groups of 5 negative tiles, that is
-1 -1
-1 -1
-1 -1
-1 -1
-1 -1
Think of it as you having each of the -1 inside it's distinct tile. Now adding up these tiles you have -10.
Therefore 2(-5) is -10 using integer tiles.
If we are to use the number line, first draw your number line, then think of it as jumping twice while each jump is -5 big.
So the first jump from 0 will land on -5 and the second jump will land on -10 and that is the required answer using the number line.
