Answer:
B, C, E
Step-by-step explanation:
Answer choice A):
$300 × = $75
* This answer choice represents the calculation of discount only and not the final selling price of the bicycle.
Answer choice B):
$300 × = $225
* This answer choice represents the calculation of the final selling price of the bicycle.
Answer choice C)
$300 × (1 - ) = $225
* This answer choice represents the calculation of the final selling price of the bicycle.
Answer choice D):
$300 - 1/4
*This answer choice shows an incorrect equation which neither represents the calculation of the discount nor the final selling price of the bicycle.
Answer choice E):
$300 - × $300
Applying the rule of PEMDAS,
We start with division; 1 ÷ 4 = 0.25
Then we go to multiplication; 0.25 × $300 = $75
Finally we do the subtraction; $300 - $75 = $225
* This answer choice represents the calculation of the final selling price of the bicycle.
Answer:
6ab
Step-by-step explanation:
3 x a x 2 x b
= 3 x 2 x a x b ( because multiplication is commutative, which basically means you can move the numbers and variables anywhere in the expression).
= 6ab ( we leave out the multiplication signs. They are understood.)
Solution:
We have been asked to find the simplified expression of
Answer:
CD with the line bar over it ↔
DC with the line bar over it ↔
Step-by-step explanation:
There are two possible names for the line
CD with the line bar over it ↔
DC with the line bar over it ↔
We need the line bar over it to indicate it is a line and not a line segment. A line goes on infinitely in both directions while a line segment stops
