Answer:
You will need to buy 5 1.50lb bags of sugar to make your recipe.
Step-by-step explanation:
This problem can be solved by consecutive rules of three.
A large recipe calls for 3.18kg of sugar. Your bags of sugar are measured in pounds (lb). Remembering that 1kg=2.20462lb
How many lbs of sugar you will need to buy?
1 kg - 2.20462lb
3.18 kg - x lb
How many 1.50lb bags of sugar will you need to buy to make your recipe?
1 bag - 1.50 lb
x bags - 7 lb
You will need to buy 5 1.50lb bags of sugar to make your recipe.
Answer:
The value of x would be -3.
Step-by-step explanation:
Consider the complete question is,
'Which represents all the values of x that make the rational expression undefined?'
Since, the rational expression is defined for all real values except those for which denominator is equal to zero,
If 3x + 9 = 0,
3x = -9
Hence the values of x that make the rational expression undefined would be -3.
Answer:
Step-by-step explanation:
The total amount of flour, in cups, Matthew needs is equal to . Because he only has 4 cups, we can write the following expression to determine how many additional cups of flour he needs:
Using the together rate, it is found that it would take the assistant 31 hours and 30 minutes to do it alone.
<h3>What is the together rate?</h3>It is the sum of each separate rate.
In this problem, the rates are given as follows:
Hence:
2x = 63
x = 31.5.
It would take the assistant 31 hours and 30 minutes to do it alone.
