Hello!
so we have a total weight of 5.1kg and we are told that each penny weighs 2.5g.
so we need to convert either one to the same units first. we know there are 1000g in 1kg so 2.5g=0.0025kg now we have both in the units of kg, so we can just take 5.1kg/0.0025kg=2040 pennies in the bag.
we can check ourselves here by taking 2040 * 2.5g and we get 5100grams which equals 5.1kg
hope this helps. any questions please just ask. thank you kindly
Answer:
$33.00
Step-by-step explanation:
You find out how much the sale price is by subtracting 25% of 40 from 40:
40 - [(.25)(40)] and that equals 30. So the sale price is $30. Now if the tax is 10% (.1 in decimal form), we find the total cost by adding .1(30) to 30:
30 + [(.1)(30)] which is $33

Answer:
Proportion states that the two fractions or ratios are equal
Given the equation: 
By cross multiply we get;
Using distributive property; 
Subtract 0.4 from both sides we get;
Subtract 1.5x from both sides we get;
Divide both sides by 0.1 we get;
Simplify:
x = 56
Therefore, the value of x that satisfy the equation is, 56
