..
Step-by-step explanation:
If the dress is $52 all you have to do I subtract the total ($125)from the amount the dress was, which is 76
Range is 6 and the mode is 8
Answer:
2kg
Step-by-step explanation:
Let the sum of the other 2 bricks be R. Given that the heaviest brick weighs 2/3 times as much as the other 2 bricks in total, then the weight of the heaviest brick H in terms of the weight of the other 2 will be
H = 2/3 * R
= 2R/3
Given that the 3 bricks weigh 5kg in total then,
2R/3 + R = 5
Multiply through the equation by 3
2R + 3R = 15
5R = 15
Divide both sides by 5
R = 15/5
= 3
The weight of the heaviest brick is 2R/3. Since R = 3, the heaviest block weighs
= 2 * 3/3
= 2kg
Addition and multiplication are commutative property so that mean no.
In this case, you have to do division.
Your answer is 6x = 72
x = 12
Hope this helps :)
