Answer:

The youth group bought 35 geraniums and 45 daisy plants.

Step-by-step explanation:

We can solve this using a system of equations:

x + y = 80

4x + 6y = 410

X = Geraniums

Y = Daisies

First, let's solve for a variable in the first equation. I am going to solve for y in the first equation:

x + y = 80

y = -x + 80

Now that we have solved for y we can plug that back in to the 2nd equation:

4x + 6(-x + 80) = 410

4x - 6x + 480 = 410

-2x + 480 = 410

-2x = -70

x = 35

Now that we have found the amount of geraniums we can plug it back into the first equation and solve for y:

35 + y = 80

y = 45

Therefore the youth group bought 35 geraniums and 45 daisy plants.

Check:

(35) + (45) = 80

80 = 80

4(35) + 6(45) = 410

140 + 270 = 410

410 = 410

I hope this helps!!

6x²+15x-4x-10

3x(2x+5)-2(2x+5)

(2x+5)(3x-2)

Answer:

20

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 80.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 80=100%.

Step 4: Similarly, x=25%.

Step 5: This results in a pair of simple equations:

80=100% (1).

x=25%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

{80} = {100%} {25%}

Step 7: Again, the reciprocal of both sides give

{80}= {25} {100}

x=20

Therefore, 25% of 80 is 20

Answer:

The steps are :

[tex] {tan}^{2} θ - {cot}^{2} θ = {sec}^{2} θ(1 - {cot}^{2} θ)[/tex]

[tex]RHS = {sec}^{2} θ(1 - {cot}^{2} θ)[/tex]

[tex]RHS = (1 + {tan}^{2} θ)(1 - \frac{1}{ {tan}^{2} θ} )[/tex]

[tex]RHS = (1 + {tan}^{2} θ)( \frac{ {tan}^{2}θ - 1}{ {tan}^{2} θ} )[/tex]

[tex]RHS = - \frac{(1 + {tan}^{2}θ)(1 - {tan}^{2} θ)}{ {tan}^{2} θ}[/tex]

[tex]RHS = - \frac{(1 - {tan}^{4} θ)}{ {tan}^{2} θ} [/tex]

[tex]RHS = \frac{ {tan}^{4} θ - 1}{ {tan}^{2}θ } [/tex]

[tex]RHS = {tan}^{2} θ - \frac{1}{ {tan}^{2}θ } [/tex]

[tex]RHS = {tan}^{2} θ - {cot}^{2} θ[/tex]

[tex]RHS = LHS (proven)[/tex]

Answer:

6800

Step-by-step explanation:

The coordinates of the B is obtained as (-5, 3).

Coordinates are 2 numbers (Cartesian coordinates) or a letter and a number that point to a specific point on a grid known as a coordinate plane.

Now, as per the given question;

The coordinates of A is given as (1, 7).

The coordinates of mid point M is given as (-2, 5).

The coordinates are listed in pairs, with the x value at the top.

The shift in the x location is as follows:

1 - (-2) = 3

The change in y position is as follows:

7 - 5 = 2

Because the midpoint is half - way between B and A, the change will remain constant, so x is;

- 2 - 3 = -5

And for is;

5 - 2 = 3

Therefore, the values of the coordinates of B is found as (-5, 3).

The correct question is-

If M (-2, 5) is the midpoint of AB and the coordinates of A are (1, 7), what are the coordinates of B?

Step-by-step explanation:

First find 28% of $19.50:

($19.50) / (100) × (28) = $5.46

Now minus the 285 from the original price:

($19.50) - ($5.46) = $14.04

The answer is $14.04

(0, 1)

(1, 4)

(2, 7)

Step-by-step explanation:

Substitute x with each number and solve equation.

In order to solve how many problems each person has solved, you have to multiply the fraction by the number of problems on their assignment. To do this, you multiply the numberator by the number of problems and then divide that by the denominator for both Dustin and Kelsey.

For Dustin, 3/8 * 24 = 72 / 8 = 9 problems completed

For Kelsey, 4/15 * 30 = 120/15 = 8 problems completed

Dustin has completed more problems

Answer:9
