Answer:
1. 8 bags of rice
2. $1.50 per bag
3. $30
Step-by-step explanation:
For #1, you set up the proportion 3 over 2 is equal to 12 over x and solve by cross multiplication. Then, you should get the answer of 8 bags. For #2, you do $3 divided by 2 to get the answer of $1.50. For #3, you use your answer from #2 and do 1.5 times 20 to get $30.
1. The cost of 12 bags of rice is 18 dollars.
2. Per bag of rice cots 1.5 dollars.
3. The cost of 20 bags of rice is 30 dollars.
What is a unitary method?A unitary method is a mathematical technique for determining the value of a single unit then we can derive any no. of units by multiplying it by the single unit.
Given it costs 3 dollars for 2 bags of rice.
We know if we determine the cost of one bag of rice we can find out the cost of any no. bags of rice.
∴ 2 bags of rice cost 3 dollars,
So, 1 bag of rice cots (3/2) dollars = 1.5 dollars.
1. At the rate of 1.5 dollars per bag of rice 12 bags of rice will cost (1.5×12) dollars = 18 dollars.
2. The cost per bag of rice is 1.5 dollars.
3. The cost of 20 bags of rice is (1.5×20) dollars = 30 dollars.

Steven and Anna start running from the school. Steven starts 15 seconds before Anna and runs at a rate of 3 feet per second. Anna runs at a rate of 4 feet per second. After how many seconds would Anna catch up with Steven?
Answer:
11.25 feet
Step-by-step explanation:
3*15=45;
45/4=11.25
Answer: After 15 seconds, Anna will catch up with Steven.
Step-by-step explanation: Set up the equation so that their distances will be equal at some time, x.
Distance = speed × time
3x + 15 = 4x . Subtract 3x from both sides
15 = 4x-3x
15 = x The time is 15 seconds.
At that point their distances will be equal at 60 feet.
3(15) + 15 = 60
4(15) = 60

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Cost of each calculator = $31.25
Cost of x calculators.
= 31.25x
Now,
The total cost of the calculators = $500.
The number of calculators bought.
= 500/31.25
= 16
Thus,
The cost of x calculators is 31.25x.
The number of calculators bought is 16.

Answer:
(69)(3)−8 = 15
199≠15
False

Complete the net worth statement by determining the total assets and total liabilities. What is the net worth?
A) $200
B) $2,000
C) $10,700
D) $12,700
Answer:
B
Step-by-step explanation:
1. Add all of the assets($12,700) and all of the liabilities($10,700).
2. Subtract the liabilities from the assets.
The total net worth of the given assets and liabilities is $2000.
What is the net worth?The net worth is the difference between the total assets and the total liabilities.
net worth = assets - total liabilities
The total of all the assets is $12,700 and the total of all of the liabilities is $10,700.
net worth = assets - total liabilities
net worth = $12,700 - $10,700
= $2000
Therefore, the total net worth of the given assets and liabilities is $2000.
