By solving a system of equations we will see that Anna works 2 hours washing cars and 5 hours landscaping.

First, we need to define the variables that we will be using, these are:

We know that she works 7 hours in total and earns $78 in total, so we can write the system of equations:

x + y = 7

x*$9 + y*$12 = $78

Isolating x on the first equation we get:

x = 7 - y

Replacing this on the other equation we get:

(7 - y)*$9 + y*$12 = $78

$63 - $9*y + $12*y = $78

$63 + $3*y = $78

$3*y = $78 - $63

$3*y = $15

y = $15/$3 = 5

Then the value of x is:

x = 7 - y = 7 - 5 = 2

Answer:

x = 9

Step-by-step explanation:

Start by dividing both sides by the singular number, 3. We divide by 3 and not 21 because 21 is the result of the equation, not the coefficient.

[tex]\frac{3\left(x-2\right)}{3}=\frac{21}{3}[/tex]

We got 21 over 3 because you cannot divide 3 times an unknown number subtracted by 2 by 3. This is because we do not know the number. So that's where 21 comes in.

Next, simplify this equation by dividing whole numbers.

[tex]\frac{3}{3} = 1[/tex]

[tex]1\left(x-2\right) = \left(x-2\right)[/tex]

[tex]\frac{21}{3} = 7\\= x-2 = 7[/tex]

Lastly, add 2.

[tex]x - 2 + 2 = 7 + 2\\2 + 2 = 4\\7 + 2 = 9\\= x - 4 = 9\\x = 9[/tex]

Why x - 4 is 0: We assume x is always equal to 1, since 4 does not go into 1, the result would be 0. x - 0 = 0. Therefore, the problem became x = 9.

Answer: First you have to think about what to multiply 9 by to get a number that ends with 6. The answer to that is 3. So 9*3=36. Then you need to subtract 36 from 86. You get 50. So now you need to divide. 36/9=3 and 50/10=5. So the chef bought 3 bags of red onions and 5 bags of yellow onions.

The total amount of money spent on pass and lunch for each student is $19.28.

The first step is to determine the amount that was spent on a pass for each student. The cost of one pass can be determined by dividing the total amount spent on passes by the total number of teachers and students.

Cost of one pass = total amount spent on one pass / total number of people

Cost of one pass = 526.26 / (47 + 2)

Cost of one pass = 526.26 / 49

Cost of one pass = $10.74

The second step is to determine the amount spent on lunch for one student. This can be determined by dividing the total amount spent on lunch by the total number of students.

Cost of one lunch = total cost of lunch / total number of students

401.38 / 47 = $8.54

Total amount spent on pass and lunch for each student = cost of lunch for one student + cost of a pass for one student

$8.54 + $10.74 = $19.28

Answer: The standard form of a linear equation is Ax+By=C. To change an equation written in slope-intercept form (y=mx+b) to standard form, you must get the x and y on the same side of the equal sign and the constant on the other side. Use inverse operations to move terms.

Step-by-step explanation:

Answer:

101

Step-by-step explanation:

Since the total number of cheeseburgers was twice the number of hamburgers, let the number of sold hamburgers be h

Twice of h = 2(h)

Hence,

2(h) + h = 303

2h + h = 303

3h = 303

Divide both sides by the coefficient of h

h = 101

Therefore, the total number of hamburgers sold was 101

The graph of the equation p(x) = -3x- 1 has been plotted

The equation is given that

p(x) = -3x - 1

We know the slope intercept form of the line

y = mx + b

Where m is the slope of the line

b is the y intercept

Compare both equation

The slope of the line m = -3

The y intercept b = -1

At x = 1

The value of p(1) = -3(1) -1

= -3 - 1

= -4

At x = 2

The value of P(2) = -3(2) -1

= -6 - 1

= -7

Substitute the value for x and find the value of y.

The perimeter of the rectangle is 59.9 m.

The area of the rectangle is = 223.2 m²

the length(L) of the rectangle is = 16 m

we know that the area of the rectangle is given by

Area  = Length x Breadth

A =  LB

therefore ,

LB=  223.2

16 x B = 223.2

B = 223.2/ 16

B = 13.95 m

∴ breadth or the rectangle is 13.95 meter.

Now , we know that the perimeter of the rectangle is given by ,

(P) perimeter = 2( Length + Breadth )

P = 2(L + B)

P = 2( 16 + 13.95)

P = 2( 29.95)

P = 59.9 m

There are two closed containers and four balls can just fit in each of the containers, then container A has a smaller surface area.

A three-dimensional solid shape's capacity is referred to as its volume. It is difficult to visualize in any shape, yet this can be evaluated among forms.

As per the data in the question,

Radius, r = 30 mm

Height, h = 60 × 4 = 240 mm

Use the equation of the surface area of the cylinder, SA = 2πr² + 2πrh

SA = 2π(30)² + 2π (30)(240)

SA = 50,868.

Now, calculate the area of a rectangular prism,

Area of top and bottom,

= (60 + 60) × (60 + 60) × 2

= 120 × 120 × 2 = 28,800

Area of 2 sides,

= 2 × (60 × 120) = 14,400

Area of front and back,

Subtraction:

Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.

The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

Answer:

Line 1:  [tex]y=-x+2[/tex]

Line 2:          [tex]y=2x-1[/tex]

Step-by-step explanation:

Line 1

Staring with line one, let's find the slope!

Between the two known points, the rise, or change in y, is 2, and the run, or change in x, is -2. The slope is the rise over the run, so:

[tex]-\frac{2}{2} =-1[/tex]

The slope is negative 1! The line crosses the y-axis at [tex]y=2[/tex], so 2 is the y-intercept. Using the slope-intercept formula, the equation is:

[tex]y=-x+2[/tex]

Line 2

To find the slope of line 2, find the rise and the run between the two known points! The rise is 4, and the run is 2. Simplified, this is:

[tex]\frac{4}{2} =2[/tex]

The slope is 2! The line crosses the y-axis at [tex]y=-1[/tex], so -1 is the y-intercept. Using the slope-intercept formula, the equation is:

[tex]y=2x-1[/tex]

Answer:

y=2x-1 , y=x+2 , the solution of the system is (1,1)

Step-by-step explanation:

Lines can be expressed in the form y=mx+b where m is the slope and b is the y-intercept.

m= rise/run

Looking at the blue line:

m =2/1 =2

The slope is 2 since you rise 2 squares and run to the right one square.

We see that the line crosses the y-axis at (0,-1) so the y-intercept is -1.

Putting it all together: y=2x-1

Looking at the red line:

m = -1 / 1 = -1

We see that the line crosses the y-axis at (0,2) so the y-intercept is 2.

Putting it all together: y=1x+2 or simply y=x+2

The solution to the system is the point that satisfies both equations. Rather than solving it algebraically, we can simply look at the graph and find a point that is on both lines, aka the intersection. In this case, the intersection is (1,1).

The standard form of a quadratic function is y = 3/2x² + 17/2x - 7

From the question, the points on the quadratic equation are given as

(2,4), (3,5) and (4,3)

The standard form of a quadratic equation is represented as

y = ax² + bx + c

So, we have

Point (2,4):

4a + 2b + c = 4

Point (3,5):

9a + 3b + c = 5

Point (4,3):

16a + 4b + c = 3

Solving using an online calculator. we have

a = 3/2, b = 17/2 and c = -7

Substitute a = 3/2, b = 17/2 and c = -7 in y = ax² + bx + c

y = 3/2x² + 17/2x - 7

The possible rational zeros are x = -1 and x = 1/3 for the given function f(x) = 3x² + 2x - 1.

The quadratic function is defined as a function containing the highest power of a variable is two.

The function is given in the question as:

f(x) = 3x² + 2x - 1

To determine possible rational zeros for the given function.

f(x) = 3x² + 2x - 1

For finding rational zeros, f(x) = 0

3x² + 2x - 1 = 0

3x² + 3x - x - 1 = 0

3x(x +1) - 1(x +1) = 0

(x +1)(3x - 1) = 0

(x +1) = 0 and (3x - 1) = 0

x = -1 and 3x = 1

x = -1 and x = 1/3

Thus, the possible rational zeros are x = -1 and x = 1/3 for the given function f(x) = 3x² + 2x - 1.
