Answer:

The students bought 16 azaleas plants.

Step-by-step explanation:

Given that:

Total plants bought by student council = 36

Cost of each azaleas plant = $6

Cost of each lily plant = $5

Total amount spent = $196

Let,

x be the number of azaleas

y be the number of lilies

x+y = 36       Eqn 1

6x+5y=196     Eqn 2

Multiplying Eqn 1 by 6

6(x+y=36)

6x+6y=216      Eqn 3

Subtracting Eqn 2 from Eqn 3

(6x+6y)-(6x+5y)=216-196

6x+6y-6x-5y=20

y=20

Putting y=20 in Eqn 1

x+20=36

x=36-20

x=16

Hence,

The students bought 16 azaleas plants.

Answer:

x = -5

y = 6

Step-by-step explanation:

3x + 7y = 27      --------------(I)

-3x + y = 21        -----------(II)

Add equation (I) & (II) and so x will be eliminated and we can find the value of y.

(I)      3x + 7y = 27    

(II)     -3x + y = 21        {add}

                8y = 48

                   y = 48/8

                   y = 6

Plugin y = 6 in equation (I)

3x +7*6 = 27

3x + 42 = 27

       3x = 27 - 42

       3x = -15

         x = -15/3

x = -5

Answer:

x = 2.825

Step-by-step explanation:

-4.3(6.3x + -4.18) = -58.56

-4.3(-4.18 + 6.3x) = -58.56

(-4.18 * -4.3 + 6.3x * -4.3) = -58.56

(17.974 + -27.09x) = -58.56

17.974 + -27.09x = -58.56

17.974 + -17.974 + -27.09x = -58.56 + -17.974

0.000 + -27.09x = -58.56 + -17.974

-27.09x = -58.56 + -17.974

-27.09x = -76.534

x = 2.825175341

Answer:

F: 6x+4y=20

Step-by-step explanation:

Only line representing the equation 6x+4y=20 has y-intercept of 5.

The line that has the y-intercept = 5 is 6x + 4y = 20

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.

The standard slope intercept form:

y = mx + b

Comparing the options A,C,D and E with standard form and none of the options have b = 5.

So these options are out.

Now the options B,

Simplify, y = x/2 - 5

Compare with slope intercept form, and this equation also does not have

the y intercept as 5.

Now option F;

simplify, 6x + 4y = 20

y = -3x/2 + 5

Comparing with standard form,

And b= 5

Therefore, The line that has the y-intercept = 5 is 6x + 4y = 20

Answer:

[tex]Terms: 3\ and\ x + 2[/tex]

[tex]Product = 3x + 6[/tex]

Step-by-step explanation:

See attachment for complete question.

From the attachment, there are 3 columns and 3 rows

The 3 columns represent the first factor

To get the second factor, we have to analyze the 3 rows in the attachment.

Notice that the first row is bigger than the other two rows.

This big row will be represented with variable x

Notice that the boxes in second row are smaller than the first row and the + sign is written on each of the boxes.

This is represented with + 1

Also, notice that the boxes in third row are smaller than the first row and the + sign is written on each of the boxes.

This is also represented with + 1

Hence, the expression for the rows is x + 1 + 1 = x + 2

The product is then calculated as:

[tex]Product = 3 * (x + 2)[/tex]

[tex]Product = 3 * x + 3*2[/tex]

[tex]Product = 3x + 6[/tex]

Answer:

She should receive $3.56 from paying with a $10 bill

Step-by-step explanation:

The total cost of all her items including sales tax is

$6.44

You have to deduct this total cost from what she paid with.

$10.00 - $6.44 = $3.56

Therefore,

Sara should receive $3.56 from paying with a $10 bill.

Answer: $3.56

Step by step explanation:

1. Figure out how much the eggs cost. (1.69×2=3.38)

2. Add the price of the eggs, bacon, O.J., and sales tax together. (3.38+1.49+1.09+0.48=6.44)

3. Subtract the total ($6.44) by the amount you paid ($10). (10-6.44=3.56)

The weight of 20 buckets is 141 Kg.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

weight of 1 bucket of gravel = 7.05

weight of 20 buckets = 7.05 x 20

                                    = 141 Kg

Hence, the weight of 20 buckets is 141 Kg.

Step-by-step explanation:

I chose the points that were most visable

Answer:

b = 15.2 m

h = 13.2 m

Step-by-step explanation:

The area of a right triangle is given by:

[tex] A = \frac{bh}{2} [/tex]    (1)

Where:

b: is the base

h: is the height

If the base is 2 meters greater than the height we have:

[tex]b = h + 2[/tex]   (2)

And if the area of the triangle is 100 m², the dimensions of the base can be found by entering equation (2) into (1):

[tex]100 m^{2} = \frac{(h + 2)*h}{2}[/tex]

[tex] 200 m^{2} = h^{2} + 2h [/tex]      

[tex] h^{2} + 2h - 200 m^{2} = 0 [/tex]  

By solving the above quadratic equation we have:

[tex] h = 13.2 m [/tex]

And by entering the above value into equation (2) we have:

[tex]b = 13.2 + 2 m = 15.2 m[/tex]

Therefore, the dimensions of the base and the height are 15.2 m and 13.2 m respectively.
