The order of operations is PEMDAS (parenthesis, exponents, multiplication/division, addition/subtraction). This means that you do multiplication before adding, so 3 + 4*6 is the same thing as 3 + (4*6). Because of this, Omar did not need to use a grouping symbol.
Z^5/8
You can tell this because exponents get added together when multiplying and the fact that the fraction goes down by a multiple of 1/8.
Dividing 3.6 by 0.25 follows the following generic approach : You have
to firstly need to multiply both divisor and dividend by that number
such that the divisor becomes a whole number first .
So we multiply both dividend and divisor by 100 such that the problem converts to 3.6*100/0.25*100 = 360 being divided by 25 .
So the approach to divide a number froma decimal number is to first
convert problem into dividing the number from a whole number , by
multiplying both the number and divisor from the approriate number .
Which was in above problem comes out to be 100 .
Answer:
£72.00
Step-by-step explanation:
60*20% (0.20) = 12
60 (original price) + 12 = 72
therefore, the original price of the bag was £72.00
Answer:
- 5 < x
Step-by-step explanation:
To solve, we need to isolate the variable: x
5x - 7 < 8x + 8
Subtract 5x from both sides
5x - 5x -7 < 8x -5x + 8
- 7 < 3x + 8
Subtract 8 from both sides
- 7 -8 < 3x + 8 -8
-15< 3x
Divide both sides by 3
- 15/3< 3x/3
- 5 < x
