You buy 3 bags of sand and 2 bags of pea gravel for $21. In a second purchase (at the same prices), you buy 2 bags of sand for $10. Let x represent the price (in dollars) per bag of sand and let y represent the price (in dollars) per bag of pea gravel. Use a graph to find the price per bag of sand and the price per bag of pea gravel.
Answer:
the slope for your graph will be 3/5x
Step-by-step explanation:
in order to get our answer first we must use equations to find how much money a bag or pea gravel/sand then we can use this to make our graph.

In a cricket match, Rajat scored thrice as many runs as Devansh.
Together they fell short of 8 runs of a triple century. Find their scores.
Answer:
let jivesh score x runs so rajat scores 3x runs
total runs = 300-8 = 292 runs
so x+3x = 292
4x = 292
x = 292/4
x = 73
so jivesh score 72 runs and rajat scores 216 runs
Step-by-step explanation:
Answer:
73 for Devanesh. 219 for Rajat
Step-by-step explanation:
If a triple century is 300 then 300-8 = 292 runs that they made. They made a total of 3t+t=292. Means 4t=292. Means t=73. So 73 is the runs for Devanesh.219 for Rajat.

Step-by-step explanation:
When we are given an evaluative expression, we must follow Order of Operations: BPEMDAS to evaluate the given expression. Here’s an example:
[2 + (4 / 2)] * 10
Evaluating this:
1. [Brackets] (Parenthesis) Divide: [2 + 2] * 10
2. [Brackets] Add: 4 * 10
3. Multiply: 40
Here we see that we use Order of Operations: BPEMDAS to evaluate a given expression.
Preston started the summer owing $15 to his brother and $20 to his sister. He earned $75 mowing lawns, and paid his brother and sister back what he owed them. Which expression represents the amount of money that Preston has after paying back his brother and sister?
Answer:
$75 - $15 - $20 = $40
Step-by-step explanation:
Given that:
Money owed by Preston to his brother = $15
Money owed by Preston to his sister = $20
Total money earned by Preston = $75
Now, the money is paid back that he owed to his sister and brother.
To find:
The expression to represent the amount of money left with Preston after clearing all his dues?
Solution:
Once Preston pays back the money that he owed to his brother and sister, he will not have all $75 left with him.
He will have lesser amount of money.
Money left with Preston = Total money earned by Preston - Money owed to brother - Money owed to sister
Putting the values given as per the question statement, we get:
Money left with Preston = $75 - $15 - $20 = $40
Therefore, the expression to represent the amount of money left with Preston = $75 - $15 - $20 = $40
what is 100000x5+900-705=?
Answer:
500195
Step-by-step explanation:
The required value of the given expression 100,000 × 5 + 900 - 705 is 500,195.
The expression is given as follows:
100,000 × 5 + 900 - 705
To evaluate the expression 100,000 × 5 + 900 - 705, we follow the order of operations (also known as PEMDAS). Here's how we can solve it step by step:
Perform the multiplication: 100,000 × 5 = 500,000.
Add the result from the multiplication to 900: 500,000 + 900 = 500,900.
Subtract 705 from the previous result: 500,900 - 705 = 500,195.
Therefore, the value of the expression 100,000 × 5 + 900 - 705 is 500,195.

Your are on a roller coaster that begin 1/5 mile above ground. The roller coaster descends 1/2 mile. What is the roller coatser new location after descending
Answer:
Roller coaster is 3/10 miles in ground.
Step-by-step explanation:
Given:
Height at point = 1/5 mile
Descends height = 1/2 miles
Find:
Current location
Computation:
Current location = Height at point - Descends height
Current location = 1/5 - 1/2
Current location = -3/10
So,

Change the word sentence into a mathematical equation. Tell what each variable represents.
1. A music club membership costs $17.00 and $7.00 per CD.
2. The total cost of a carpet is $3.00 times the number of square feet.
3. The amount of money you earn for allowance is $20 times the number of months.
4. The cost of belonging to a fitness club is $200 to join and $30 a month in membership dues.
Answer:
1. $17 + $7C.
This equation provides the total cost if you want to purchase a music CD along with a music club membership. C represents the amount of CDs you wish to purchase, and since each CD costs $7, the amount of money you would need to purchase C amount of CDs is $7C.
2. $3A.
This equation provides the total cost of the area of carpet you want to purchase. A represents the area of the carpet that you want to purchase, measured in square feet as provided by the question, and since each square foot costs $3, the total cost is $3A.
3. $20M.
This equation provides the total money you earn for allowance after M months. M is the number of months that have passed, and since you earn $20 for allowance every month, the total allowance you have earned is $20M.
4. $200 + $30M.
This equation provides the total cost for joining and staying in a fitness club for M months. The initial cost, $200, is applied no matter how many months you join, so we add it from the start; since each month, M, you have to pay $30, the total amount of membership dues is $30M.

Find the width w of a box with volume V = 120 cm3, l = 3 cm and h = 5 cm.
Answer:
8
Step-by-step explanation:
the volume of a box is L x W x H
so if you take the length x height, you can divide the volume by that to get your width.
hope this helps!! :)
The width of the rectangular box will be; 8cm
What is the volume of a rectangular box?Given that the formula for calculating the volume of a rectangular box is expressed as:
V= w l h
Where L is the length
w is the width
h is the height
Given the following parameters;
Length l = 3 cm
Volume V = 120cm³
Height = 5cm
Find the width of the box as :
V= w l h
120 = w x 3 x 5
w = 120/ 15
w = 8
Hence, the width of the rectangular box will be 8 cm.
