I need help on number 3 on my math homework sheet and it's 8,376+blank=45,791 please help me I'm so stuck bye now
the sum of two numbers is 30 and their difference is 12
Final answer:
The student's question involves finding two numbers with a known sum of 30 and a difference of 12. By setting up a system of linear equations and solving them, the two numbers are determined to be 21 and 9.
Explanation:
The student is asked to solve a system of linear equations where two numbers have a known sum and difference. Let's define the numbers as x and y. According to the problem, x + y equals 30, and x - y equals 12. We can solve these equations simultaneously to find the values of x and y.
Adding the two equations: (x + y) + (x - y) = 30 + 12, which simplifies to 2x = 42, so x = 21. Substituting x back into one of the original equations, 21 + y = 30, gives y = 9. Therefore, the two numbers are 21 and 9.
This exercise demonstrates one of the fundamental rules of mathematics used to find unknown quantities. Regardless of the context, such arithmetic rules are universally valid, and misunderstanding these rules, like miscounting goats or students as in the provided examples, leads to errors.

The price of a pair of pants is $29.95 and the sales tax is 5%.
What is the total cost of the pair of pants?
Please help me I NEED HELP BAD
To find the total cost of a pair of pants priced at $29.95 with a 5% sales tax, calculate $29.95 multiplied by 0.05 for the tax amount, add that to the original price, and the total cost including tax is $31.45.
To calculate the total cost of a pair of pants with a sales tax, you first need to determine the amount of tax to be added to the price. Here's how you can do it:
Convert the sales tax rate from a percent to a decimal by dividing by 100. For a 5% sales tax, you get 0.05.
Multiply the price of the item by the decimal sales tax rate to find the amount of sales tax. So, $29.95 imes 0.05 = $1.4975.
Round the sales tax to the nearest cent, giving us $1.50.
Add the sales tax to the original price of the item. Therefore, $29.95 + $1.50 = $31.45, which is the total cost with tax.

Rachel and Abby are trying to solve a science homework question. They need to find how much a rock that weighs 6 pounds on Earth would weigh on the moon. They know they can multiply weight on Earth by about 0.16 to find weight on the moon. Select the partial products Rachel and Abby would need to add to find the product of 6 and 0.16. Mark all that apply.
A. 0.22 B.0.6 C.3.65 D.3.6 E0.36
Answer:
Step-by-step explanation:
A,C,E
The partial products method helps break down a multiplication problem that can simplify calculations. In this case, for the multiplication of 6 * 0.16, we would select 0.6 (6 * 0.1) and 0.36 (6 * 0.06) as the partial products.
Explanation:This is a multiplication problem regarding how much a rock would weigh on the moon if it weighs 6 pounds on Earth. To find the weight of a rock on the moon, we multiply the weight on Earth by the lunar weight factor, which is 0.16 in this case. Hence: 6 * 0.16 = 0.96.
Now, when we break down the multiplication using the partial product method, 6 * 0.16 can be viewed as (6*0)+(6*0.1)+(6*0.06), which equals 0 + 0.6 + 0.36. So the correct answers are B.0.6 and E.0.36.

Alina spent no more than $45 on gas for a road trip. The first gas station she used charged $3.50 per gallon and the second gas station charged $4.00 per gallon. Which inequality relates the number of gallons of gas she bought at the first station, x, the number of gallons of gas she bought at the second station, y, and the total amount she paid? What are the possible values of y? 3.5x + 4y ≥ 45, y ≥ 11.25 3.5x + 4y ≥ 45, 0 ≤ y ≤ 10.375 3.5x + 4y ≤ 45, 0 ≤ y ≤ 11.25 3.5x + 4y ≤ 45, y ≥ 10.375
Answer:
The correct option is 3.
Step-by-step explanation:
Let the number of gallons of gas she bought at the first station be x and the number of gallons of gas she bought at the second station be y.
It is given that the first gas station she used charged $3.50 per gallon and the second gas station charged $4.00 per gallon.
Total cost is defied as
[tex]T=3.50x+4.00y[/tex]
Alina spent no more than $45 on gas for a road trip.
[tex]T\leq 45[/tex]
[tex]3.50x+4.00y\leq 45[/tex] .... (1)
If she bought all number of gallons from the second station, then
[tex]4y\leq 45[/tex]
Divide both sides be 4.
[tex]y\leq 11.25[/tex]
Number of gallon can not negative.
[tex]0\leq y\leq 11.25[/tex] .... (2)
Inequality (1) relates the number of gallons of gas and inequality (2) represent all the possible values of x.
Therefore, the correct option is 3.
Answer:
3.5x + 4y ≤ 45, 0 ≤ y ≤ 11.25 (c)

Michael drinks 355 milliliters of orange juice and puts 6 centiliters of syrup on his pancakes for breakfast. How many milliliters of liquid did he consume?
Answer:
415 milliliters
Step-by-step explanation:
Given,
The quantity of orange juice she consumes = 355 milliliters,
And, the quantity of syrup she consumes = 6 centiliters,
Since, 1 centiliters = 10 milliliters
⇒ The quantity of syrup she consumes = (10×6) milliliters = 60 milliliters
Thus, the total liquid she consumed = The quantity of orange juice she consumes + the quantity of syrup she consumes
= 355 + 60
= 415 milliliters
