Mrs. Gomez has two kinds of flowers in her garden. The ratio of lilies to daises in the garden is 5:2
If there are 20 lilies, what is the total number of flowers in her garden?
Answer: 28 flowers
Step-by-step explanation: if the ratio is 5 : 2 that means that the ratio was multiplied by four to get 20 for the number of lilies . multiply 2 times 4 to get 8 and then add that to the totally number of lilies to get 28 flowers in total .
There are 28 flowers in her garden.
Ratio of flowers lilies to daises are 5:2, Number of lilies = 20 by this information total number of flowers in Mrs. Gomez to be determine.
The ratio can be defined as between two quantity the quantity of 1 present relative to quantity 2.
Let there are "d" number of daises in garden, than ratio can be.
20/d = 5/2

Step-by-step explanation:
Which of the following equations have no solution? Check all that apply.
6x + 1 = 3(2x – 4)
2 - 5x = 7x – 12
4(3 – x) = 2(6 - 2x)
5(x + 2) = 2(x – 4)
-4(x + 3) = 4(x - 1)
ANSWERS (A,E)
The equation that have no solution is: 6x + 1 = 3(2x - 4).
The correct option is the first option.
Here, we have to check which of the equations have no solution, we need to solve each equation and see if they lead to a contradiction or an inconsistency.
If the variable (x) cancels out during the solving process, it means that the equation has no solution.
1) 6x + 1 = 3(2x - 4)
Expand the right side: 6x + 1 = 6x - 12
Subtract 6x from both sides: 1 = -12
In this case, we end up with a contradiction (1 = -12), which means there is no solution.
2) 2 - 5x = 7x - 12
Add 5x to both sides: 2 = 12x - 12
Add 12 to both sides: 14 = 12x
Divide by 12: x = 14/12 = 7/6
This equation has a solution.
3) 4(3 - x) = 2(6 - 2x)
Expand both sides: 12 - 4x = 12 - 4x
Subtract 12 from both sides: -4x = -4x
In this case, the variable (x) cancels out, which means any value of x would satisfy the equation.
So, this equation has infinitely many solutions.
4) 5(x + 2) = 2(x - 4)
Expand both sides: 5x + 10 = 2x - 8
Subtract 2x from both sides: 3x + 10 = -8
Subtract 10 from both sides: 3x = -18
Divide by 3: x = -18/3 = -6
This equation has a solution.
5) -4(x + 3) = 4(x - 1)
Expand both sides: -4x - 12 = 4x - 4
Add 4x to both sides: -4x - 4x - 12 = 4
Combine like terms: -12 - 4 = 8x
Combine like terms on the left side: -16 = 8x
Divide both sides by 8 to isolate x: x = -2
This equation has a solution.
So, the equation that have no solution is: 6x + 1 = 3(2x - 4).
Hence, The correct option is the first option.

A. [tex]y = 5x + \frac{3}{10}[/tex]
B. [tex]y = 5x + 3[/tex]
C. [tex]y = \frac{1}{5} x + \frac{3}{25}[/tex]
D. [tex]y = \frac{1}{2} x + 6[/tex]
Answer:
B. [tex]y = 5x + 3[/tex]
Step-by-step explanation:
Given
Equation 1: [tex]y = 3x - 2.[/tex]
Equation 2: [tex]10(x + \frac{3}{5} ) = 2y[/tex]
Required:
Equivalent of equation 2
To get an equivalent of equation 2 (in slope intercept form), first we have to simplify equation 2
[tex]10(x + \frac{3}{5} ) = 2y[/tex]
Open the bracket
[tex]10*x + 10 *\frac{3}{5} = 2y[/tex]
[tex]10x + \frac{30}{5} = 2y[/tex]
Simplify fraction
[tex]10x + 6 = 2y[/tex]
Divide through by 2
[tex]\frac{10x}{2} + \frac{6}{2} = \frac{2y}{2}[/tex]
[tex]5x + 3 = y[/tex]
Re-arrange
[tex]y = 5x + 3[/tex]
The next step is to compare each of option A through D with [tex]y = 5x + 3[/tex]
A.
[tex]y = 5x + \frac{3}{10}[/tex] is not equal to [tex]y = 5x + 3[/tex]
We check the next available option
B.
[tex]y = 5x + 3[/tex] is equal to [tex]y = 5x + 3[/tex]
This option is equivalent to the second equation in slope-intercept form.
We check further if there are more equivalent options
C.
[tex]y = \frac{1}{5} x + \frac{3}{25}[/tex]
Convert fraction to decimal
[tex]y = 0.2x + 0.12[/tex]
This is not equal to [tex]y = 5x + 3[/tex]
D.
[tex]y = \frac{1}{2} x + 6[/tex]
Convert fraction to decimal
[tex]y = 0.5x + 6[/tex]
This is not equal to [tex]y = 5x + 3[/tex]
Hence, the only equation that is equivalent to the second equation written in slope intercept form is Option B

Lara is putting lace trim around the border of a circular tablecloth. The tablecloth has a diameter of 1.2 meters. What is the length of the lace she needs? Round to the nearest tenth of a meter.
Answer:
3.8m
Step-by-step explanation:
Since Lara is putting lace trim around the border of a circular tablecloth, by the time she finishes she has covered the circumference.
The circumference of a circle is calculated using:
[tex]C=\pi \: d[/tex]
where d is the diameter of the circle.
It was given that the diameter of the circular table cloth is 1.2 meters.
[tex]C=3.14 \times 1.2[/tex]
[tex]C=3.768[/tex]
Therefore the length of the lace she needed is 3.8m
Final answer:
Lara will need 3.8 meters of lace trim for the border of her circular tablecloth, after rounding to the nearest tenth.
Explanation:
The student is asking about the circumference of a circle, which is the total length around the circle. Given the diameter of the tablecloth as 1.2 meters, the circumference can be found using the formula C = πd, where C is the circumference and d is the diameter. The value of π (pi) is approximately 3.14. So the length of lace Lara needs is C = 3.14 × 1.2 meters = 3.768 meters. After rounding to the nearest tenth of a meter, Lara would need 3.8 meters of lace trim.
Choose the statement that is not true based on these diagrams.
38° + m∠2 + 108° = 180°
m∠A + 108° + 34° = 180°
m∠A = m∠2
m∠2 = 34°
Answer:
m∠A = m∠2
Step-by-step explanation:
38° + m∠2 + 108° = 180°
The above statement is true because the sum of angles on a straight line is 180°
m∠A + 108° + 34° = 180°
This is also true because the sum of angles in a triangle is 180°.
m∠A = m∠2
This statement is false because 34°≠32°
m∠2 = 34°
This statement is true because:
m∠2 = 180-38-108=34°
Answer:
C. m∠A = m∠2

Step-by-step explanation:
Complete Question:
Ms. Chang’s class decides to order posters that advertise a walkathon to raise money for a local charity. Ichiro obtains quotes from two different companies.Clear Prints charges $2 per poster. Posters by Sue charges $15 plus $.50 per poster.
a. For each company, write an equation Ichiro could use to calculate the cost for any number of posters.
b. For what number of posters is the cost the same for both companies? Explain.
c. Which company do you think the class should buy posters from? Explain your reasoning.
d. If Ms. Chang’s class has an $18 budget for posters, which company do you think the class should buy posters from?
e. If Ms. Chang donates an additional $10 for ordering posters, does it impact the decision made? What factors influenced your decision?
Solution:
a.
Let the number of posters be "p" so
Clear Print would take 2 * p or "2p"
Sue would take a fixed cost of $15 and 0.5p, so "15 + 0.5p"
b.
We want cost of both to be same. So we can equate:
[tex]2p=15 + 0.5p[/tex]
Now, using algebra, we can solve for "p", the number at which both of the printers will cost same. Lets do this:
[tex]2p=15 + 0.5p\\2p-0.5p=15\\1.5p=15\\p=10[/tex]
So, for 10 posters, the cost of both will be same
c.
It depends.
If the number of posters they order is LESS THAN 10, they should order from Clear Prints. If the number of posters they print is "10", then they can choose any one of the printers since cost would be same. If they print more than 10 posters, then they should choose to go with Sue, as it will cost less.
d.
If the budget is $18, they can get:
Clear Prints = 18/2 = 9 posters made
Sue = 15 already gone as fixed cost, so remaining is 18 - 15 = 3
At 0.5 per poster, 3/0.5 = 6 posters
So, taking Clear Prints would be better.
e.
The budget of 18 is increase by 10, so the budget is:
18 + 10 = $28
From clear prints, you can get:
28/2 = 14 posters
From Sue, you can get:
28 - 15(fixed cost) = 13 left for posters
13/0.5 = 26 posters
Definitely, Sue gives more, so decision made at $18 budget to get Clear Prints would be impacted because they should now go with Sue since it will give them better deal and more posters.

Tia had a garden that was 2 meters long. Her brother used 458 millimeters of the length at one end as a worm farm.
How long is the part of the garden Tia can use for plants now?
1,542 centimeters
154 centimeters
1.642 centimeters
2.542 centimeters
Answer:
1542 millimeters or 15.42.42 centimeters
Step-by-step explanation:
The initial length being 2m converted to millimeters will mean we multiply by 1000 since
1m=1000mm
Therefore, 2m will be 2*1000=2000 mm
Part used was 458mm hence to get the remaining part we get the difference as follows
2000 mm -458 mm=1542 mm
Therefore, the length that can be used now is 1542 mm or 15.42 cm

When I went to the store, I purchased four items. The following shows the cost of three of the items:
$1.50
$3.00
$4.00
The line to the checkout was pretty long, so to quench my boredom I started playing with my pocket calculator while waiting.
I found out, to my surprise, that the four prices of the four items I purchased added to the same number as I got when I multiplied the four prices together.
What was the price of the fourth item?
The price of the 4rth item is $0.50.
How to find the price of the 4rth item?The three prices add to 1.50 + 3.00 + 4.00 = $8.50.
The three prices multiply to 1.50 x 3.00 x 4.00 = $18.00.
You might see that adding another $0.50 will take the total to $9.00, and multiplying by another $0.50 will take the product to $9.00 also, but the answer can also be found using algebra. Let's call the unknown price P:
1.50 + 3.00 + 4.00 + P = 1.50 x 3.00 x 4.00 x P
8.50 + P = 18.00 x P
8.50 = 18.00 x P - P
8.50 = 17.00 x P
8.50/17.00 = P
P = 0.50.

To solve the puzzle, we create an equation with the fourth price as 'x' and set the sum of the prices equal to the product of the prices. After simplifying, we find that the fourth item must cost $2.00 to satisfy the condition.
Explanation:
The student is faced with a mathematical puzzle involving the addition and multiplication of prices of items purchased. The condition is that the prices added together equals the product of the prices. Given three of the prices as $1.50, $3.00, and $4.00, let us assume the price of the fourth item is x. Therefore:
Sum of prices: $1.50 + $3.00 + $4.00 + xProduct of prices: $1.50 × $3.00 × $4.00 × xThe equation to solve is:
$1.50 + $3.00 + $4.00 + x = $1.50 × $3.00 × $4.00 × x
Simplifying the equation:
$8.50 + x = $18.00 × x
Subtracting $8.50 from both sides gives us:
x = $18.00 × x - $8.50
Dividing both sides by x:
1 = $18.00 - $8.50 / x
Finally, solving for x:
x = $18.00 / ($18.00 - 1)
x = $2.00
Thus, the price of the fourth item is $2.00.
