1. Multiplies the number by 5: ( 5x )
2. Subtracts 60 from the result: ( 5x – 60 )
3. This result equals the number he started with: ( 5x – 60 = x )
Now, we can solve the equation ( 5x – 60 = x ) step-by-step.
Step 1: Move ( x ) to the left side.

To find out how long it will take to fill the aquarium, we first need to calculate the total volume of the aquarium, which consists of the volumes of both the square prism and the square pyramid.
### Step 1: Calculate the Volume of the Square Prism
The formula for the volume of a prism is:
[
V = text{Base Area} times text{Height}
]
For a square prism:
– Base Area = side × side = ( 9 , text{ft} times 9 , text{ft} = 81 , text{ft}^2 )
– Height = 8 ft
So, the volume of the prism is:
[
V_{text{prism}} = 81 , text{ft}^2 times 8 , text{ft} = 648 , text{ft}^3
]
### Step 2: Calculate the Volume of the Square Pyramid
The formula for the volume of a pyramid is:
[
V = frac{1}{3} times text{Base Area} times text{Height}
]
For the pyramid:
– Base Area = ( 9 , text{ft} times 9 , text{ft} = 81 , text{ft}^2 )
– Height = 7 ft
So, the volume

To solve the problem, we need to express the total amount of flour used for cakes and brownies in terms of an inequality. Let ( c ) represent the number of cakes and ( b ) represent the number of batches of brownies. The total amount of flour used can be expressed as:
[ 3c + 4b leq 57 ]
Now, let’s plug in each option to see if it satisfies this inequality:
1. 3 cakes and 2 batches of brownies:
[ 3(3) + 4(2) = 9 + 8 = 17 quad (text{Valid}) ]
2. 4 cakes and 6 batches of brownies:

To graph the linear inequality (-6x – 3y ≥ -3), follow these steps:
1. Rewrite the inequality: First, we can rearrange it into slope-intercept form (y = mx + b).
Start by isolating y:
[
-3y ≥ 6x – 3
]
Divide each term by -3 (remember to flip the inequality sign):
[
y ≤ -2x + 1
]
2. Graph the related equation: The boundary line is (y = -2x + 1).
– The y-intercept is (0, 1).
– The slope is -2, meaning for every 1 unit you move to the right, you move down 2 units.
Plot the points (0, 1) and (1, -1) and draw a dashed line (because it’s a “greater than or equal to” inequality).
3. Shade the appropriate area: Since the inequality is (y ≤ -2x + 1), you shade below the line, indicating all the points that satisfy the inequality.
4. Identify the equation from the graph: The correct inequality represented by the graph is (y ≤ -2x + 1).
This indicates all the points where y values are less than or equal to the line defined by (-2x

Let’s solve the first system of equations:
1. Equations:
[
7x + 2y = -33 quad text{(1)}
]
[
-49x – 5y = 177 quad text{(2)}
]
We can multiply equation (1) by 5 to eliminate (y):

To find the height of the oblique cone, we can use the formula for the volume of a cone:
[
V = frac{1}{3} pi r^2 h
]
where ( V ) is the volume, ( r ) is the radius, and ( h ) is the height.
Given that the diameter of the cone is 12 units, the radius ( r ) is:
[
r = frac{d}{2} = frac{12}{2} = 6 text{ units}
]
Now, we know the volume ( V = 120pi ). Plugging the values into the volume formula, we have:
[
120pi = frac{1}{3} pi (6^2) h
]
This simplifies to:
[
120pi = frac{1}{3} pi (36) h
]
Multiplying both sides by 3 to eliminate the fraction:
[
360pi = 36pi h
]
Next, we can divide both sides by ( 36pi ) to solve for ( h ):
[
h = frac{360pi}{36pi} = 10 text{ units}

Let’s tackle your questions one by one.
1. Write the standard form equation of the line that passes through the point p and is parallel to the line l.
First, let’s identify the slope of the given line l, which is in slope-intercept form ( y = mx + b ). Here, the slope ( m ) is ( frac{8}{3} ).
Since the line we want is parallel, it will have the same slope. So, the slope of our desired line is also ( frac{8}{3} ).
Using the point-slope form of a line’s equation, which is ( y – y_1 = m(x – x_1) ), we can substitute ( p(-1, 0) ) into the equation:
[
y – 0 = frac{8}{3}(x + 1)

The correct statement is: The heating bill will be about $95 for an average monthly temperature of 40°F.
Explanation: In least squares regression, the line generated is used to estimate or predict values based on the existing data. When Sal inputs the temperature of 40°F into the regression equation, it will yield an approximate predicted value for the heating bill. While it won’t be exact, it will provide a reasonable estimate based on the trend established by the previous data. The other options either imply a certainty that isn’t inherent in predictions or suggest limitations that don’t apply as long as the regression model is well-fitted.

Solve for x:- Add x to both sides:[5x - 3 = -13]- Add 3 to both sides:[5x = -10]- Divide by 5:[x = -2] 3. SubstitRead more
To find the solution (x, y) to the system of equations, we can set the two expressions for y equal to each other since they both equal y:
1. Set the equations equal:
[
4x – 3 = -x – 13
]
2. Solve for x:
– Add x to both sides:
[
5x – 3 = -13
]
– Add 3 to both sides:
[
5x = -10
]
– Divide by 5:
[
x = -2
]
3. Substitute x back into one of the original equations to find y. Using (y = 4x – 3):
[
y = 4(-2) – 3 = -8 – 3 = -11
]
So, the solution to the system of equations is:
[
boxed{(-2, -11)}
]
This means that the point of intersection of the two lines represented by the equations is (-2, -11). Feel free to reach out for more help!

Substitute the value of y:Since both equations are equal to ( y ), we can set them equal to each other:[-6 = 4x + 12] 3. Solve for x:- Subtract 12 from both sides:[-6 - 12 = 4x][-18 =Read more
To solve the system of equations:
1. Identify the equations:
– Equation 1: ( y = -6 )
– Equation 2: ( y = 4x + 12 )
2. Substitute the value of y:
Since both equations are equal to ( y ), we can set them equal to each other:
[
-6 = 4x + 12
]
3. Solve for x:
– Subtract 12 from both sides:
[
-6 – 12 = 4x
]
[
-18 = 4x
]
– Divide by 4:
[
x = -frac{18}{4} = -frac{9}{2} = -4.5
]
4. Substituting x back to find y:
Since ( y = -6 ) is given, we don’t need to substitute ( x ) again into the second equation.
5. Solution:
The solution to the system of equations is ( (x, y) = left(-frac{9}{2}, -6right) ) or ( (-4.5, -6) ).

To find out how many cars you both need to wash to earn the same amount of money, we can set up equations for both of you.
1. Your Earnings: You spend $25 on supplies and earn $10 for each car washed.
– Earnings = $10 * number of cars – $25
2. Friend’s Earnings: Your friend spends $55 on supplies and earns $13 for each car washed.
– Earnings = $13 * number of cars – $55
We want to find the number of cars (let’s call it ( x )) where both earnings are equal:
[
10x – 25 = 13x – 55
]
Now, let’s solve for ( x ):
1. Rearranging the equation gives:
[
-25 + 55 = 13x – 10x
]
[
30 = 3x
]
2. Divide both sides by 3:
[
x = 10
]
So, you need to wash 10 cars to earn the same amount of money as your friend!
