Amelia is selling potted plants at her nursery. She charges $12 for each succulent and $4 for each ivy. She sold 34 potted plants and made $240. How many of each plants did she sell?
Let, she sold x and y numbers of succulent and ivy plants.
So,
x + y = 34 ...1)
12x + 4y = 240 ...2)
Putting value of x from 1) to 2), we get :
12( 34 -y ) + 4y = 240
408 - 12y + 4y = 240
8y = 168
y = 21
x = 13
Therefore, she sell 13 succulent and 21 ivy plants.
Hence, this is the required solution.

Sales Daria sells televisions. She earns a fixed amount for each television and an additional $30 if the buyer gets an extended warranty. If Daria sells 15 televisions with extended warranties, she earns \$1,500 . How much is the fixed amount Daria for each television? The fixed amount Daria ears for each television she sells is
Answer:
$70
Step-by-step explanation:
Daria's total income = fixed income + variable income
Let
Daria's Fixed income = x
additional $30 if the buyer gets an extended warranty
Daria's variable income = 30s
Where,
s = number of televisions with extended warranties she sells
If Daria sells 15 televisions with extended warranties, she earns \$1,500. Find her fixed income
Daria's total income = fixed income + variable income
1500 = x + 30(15)
1500 = x + 450
1500 - 450 = x
1,050 = x
x = $1,050
Daria's total fixed income = $1,050
How much is the fixed amount Daria for each television?
Fixed income per television = Total fixed income / number of television sold
= 1050 / 15
= 70
Fixed income per television = $70
Coach Dan has decided to surprise the athletic department's team members with new hats. Hats are sold in boxes of 18. If there are a total of 168 team members he would like to buy hats for, how many boxes would he have to order? Explain your reasoning.
Answer:
10 boxes
Step-by-step explanation:
Let's say Coach Dan orders b boxes.
Then since there are 18 hats in each box, we will have a total of 18b hats.
We would like to buy enough for 168 team members, so let's set 18b equal to 168 and solve for b:
18b = 168
b = 168/18 = 9.33
Well, we clearly need at least 9 boxes, but it's not possible to have 0.33 of a box. Thus, we must order one more box for a total of 10 boxes.

solve the proportion 9/2 = 27/2y
Answer:
y = 3
Step-by-step explanation:
We need to solve the below proportion in this problem,
[tex]\dfrac{9}{2}=\dfrac{27}{2y}[/tex]
First of all, we cross multiply both sides such that,
[tex]9\times 2y=27\times 2\\\\18y=27\times 2[/tex]
Dividing both sides by 18.
[tex]y=\dfrac{27\times 2}{18}\\\\y=3[/tex]
For the above proportion, we find that the value of y is equal to 3.
Enter the equation of the line in slope-intercept form.

x + 4 that passes through (−8, 0).
The equation of the line that passes through (−8, 0) is y = .
Answer:
[tex]y = \frac{7}{4}x +14[/tex]
Step-by-step explanation:
Given
[tex]y = \frac{7}{4}x + 4[/tex]
Required
Determine the equation of line that passes through (-8,0) and parallel to [tex]y = \frac{7}{4}x + 4[/tex]
Parallel lines have the same slope.
In [tex]y = \frac{7}{4}x + 4[/tex]
The slope, m is
[tex]m = \frac{7}{4}[/tex]
because the general form of a linear equation is:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
So, by comparison:
[tex]m = \frac{7}{4}[/tex]
Next, is to determine the equation of line through (-8,0)
This is calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex]m = \frac{7}{4}[/tex]
[tex](x_1,y_1) = (-8,0)[/tex]
So, we have:
[tex]y - 0 = \frac{7}{4}(x -(-8))[/tex]
[tex]y - 0 = \frac{7}{4}(x +8)[/tex]
[tex]y - 0 = \frac{7}{4}x +\frac{7}{4}*8[/tex]
[tex]y - 0 = \frac{7}{4}x +7*2[/tex]
[tex]y - 0 = \frac{7}{4}x +14[/tex]
[tex]y = \frac{7}{4}x +14[/tex]

A police officer wears a belt that carries an extra 10 pounds on their waistline. The police officer weighs p pounds.
Which equation can be used to find p, the total weight of police officer with the weighted belt?
t=p+10
t = 10-P
t=p-10
t = 10p
Answer: T = 10p
Step-by-step explanation: Since we don't know what is the total weight, we put the an variable, T to represent the total weight. The 10p means that the poilce officer gained 10 Pounds.

In a 30°-60°-90° triangle, what is the length of the longer leg when the length of the hypotenuse is 18 inches?
9✓2 in.
9✓3in.
18✓2 in.
18✓3in.
Answer:
9sqrt(3) in.
Step-by-step explanation:
The ratio of the lengths of the sides of a 30-60-90 triangle is:
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
If the short leg measures 1, then the hypotenuse measures 2.
The length of the hypotenuse is twice the length of the short leg.
The length of the long leg is sqrt(3) times the length of the short leg.
If the hypotenuse measures 18 in., then the short leg measures 9 in.
Then the long leg measures 9sqrt(3) in.
The length of the longer leg is 9√3 inches.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, the length of the hypotenuse is 18 inches.
The ratio of the lengths of the sides of a 30°-60°-90° triangle is:
Short leg: long leg: hypotenuse = 1 : √3 : 2
Since the hypotenuse is 18 inches, it follows that the value of 2 is 18:
2 = 18
1= 9
√3 = 9√3
Hence, the length of the longer leg is 9√3 inches.

You have 20 coins valued at 2.60. All are either quarters or nickels. Write and solve a system of equations to find the number of each coin you have.
To solve this problem you must apply the following proccedure:
1. You have a total of 21 coins, all nickels and dimes. Then:
x:nickels=5 cents
y: dimes=10 cents
x+y=21
2. You have that the total value is $1.70. Then:
5x+10y=170
3. The system of equation is:
x+y=21 (i)
5x+10y=170 (ii)
4. You have:
x+y=21
x=21-y
5(21-y)+10y=170
105-5y+10y=170
y=13 dimes
