The cost of a sweatshirt is 175% the cost of a T-shirt. A T-shirt costs $13.
What is the cost of 3 sweatshirts?
Enter your answer in the box.
Answers
Answer:A standard blank t shirt will usually start at around $1 each and go up to $4. These are going to be cotton, good quality shirts. The price difference will vary on manufacturer, brand, color and cut. So a plain white t shirt might only be $1, where the same shirt in navy blue might be $2.
Step-by-step explanation:
If you want a profit of 50% off the retail price, the calculation is straightforward. Let's say the production cost of your t-shirt amount to ₹300. When you multiply it by two, you get ₹600. And that would be the retail price of each t-shirt piece

Answers
Answer:
Step-by-step explanation:
g(x) = -3x - 3
To complete the table, you have to substitute the x values into the equation.
g(-5) = -3(-5) - 3
g(-5) = 15 - 3
g(-5) = 12
g(-3) = -3(-3) - 3
g(-3) = 9 - 3
g(-3) = 6
g(0) = -3(0) - 3
g(0) = 0 - 3
g(0) = -3
g(1) = -3(1) - 3
g(1) = -3 - 3
g(1) = -6
g(3) = -3(3) - 3
g(3) = -9 - 3
g(3) = -12

What is the percent of change from 5 to 8?
Answers
Answer:
60%
Step-by-step explanation:
5-8/5 * 100%= 60%
The percentage change from 5 to 8 is given by A = 60 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage change be represented as A
Now , the equation will be
Let the first number be p = 5
Let the second number be q = 8
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
On simplifying the equation , we get
Percentage change A = [ ( 8 - 5 ) / 5 ] x 100
Percentage change A = ( 3/5 ) x 100
Percentage change A = 60 %
Hence , the percentage change is 60 %

Benita buys 2 shirts for the same price s the taxe sale rate is 6.5%
Answers
Answer:
2s + 0.13s
2.13s
Step-by-step explanation:
One shirt costs s.
2 shirts cost 2s.
The tax rate is 6.5%, so the tax on 2s is 0.065 × 2s = 0.13s
The total cost with tax is 2s + 0.13s
You can also find the total cost by realizing that since the tax is 6.5%, the total price with tax is 1.065 times the cost, so you can write it as 1.065 × 2s = 2.13s
Answer:
2s + 0.13s
2.13s
Answer:
2.13s
and
2s+0.13s
Step-by-step explanation:
Because 2 shirts is s and 6.5 per cent would turn into 6.5 because of 2 times 1.065 is 0.13 which is the answer for part 2
Which expression represents the greatest common factor (GCF) of 54 and 153?
Answers
Answer:
9
Step-by-step explanation:
Factors are numbers we can multiply together to get another number.
A common factor is one that is a factor of two (or more) numbers.
The greatest common factor (GCF) is the largest of the common factors.
There are a few ways to find the GCF. One way is to find all the factors of both numbers, then find the ones that are common to both and choose the greatest:
The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54
The factors of 153 are: 1, 3, 9, 17, 51, 153
Therefore, the greatest common factor is 9.
The expression which represents the greatest common factor (GCF) of 54 and 153 is 3×3. Correct option is B.
The greatest common factor (GCF) of two numbers is the largest positive integer that divides both numbers evenly.
To find the GCF of 54 and 153, we need to determine the common prime factors of these two numbers and then multiply those factors together.
The prime factorization of 54:
= 2 × 3 × 3 × 3
= 2 × 3³.
The prime factorization of 153:
= 3 × 3 × 17
= 3² × 17.
The common prime factors of 54 and 153 are two factors of 3, so the GCF is 3 × 3, which can be written as 3².
Hence, 3 × 3 is the expression which represents the greatest common factor (GCF) of 54 and 153. Option B is correct.

Write the equation of a line parallel to the line y = 3x+5 and passes through the point (-7, 2)
Answers
Answer:
y=3x+23
Step-by-step explanation:
Parallel lines have the same slope, so we basically keep the same equation, but we find the new y-intercept so it accounts for (-7,2):
y = 3x + b
2 = 3(-7) + b
2 = -21 + b
23 = b
Therefore, your equation would be y=3x+23

what is 3 times 34 divided by 2 plus 8 times 5
Answers
multiplied 3x34=102 divided by 2 is 51 plus 40 because 8x5 is 91
Answer: 91
Step-by-step explanation: 3 times 34 is equal to 102... let us work out the problem together.
3 x 34 = 102
now we must divided 102 by 2 which will equal 51
Now the final step is to do 8 times 5
8 times 5 = 40
51 plus 40 = 91
this is the correct way to do the equation.
so our final answer is 91
Darlene is making a quilt that has alternating stripes of regular quilting fabric and sateen fabric. She spends $76 on a total of 16 yards of the two fabrics at a fabric store. Sateen fabric costs $6 per yard and quilting fabric costs $4 per yard. Which system of equations can be used to find the amount x (in yards) of regular quilting fabric and the amount y (in yards) of sateen fabric she purchased?
Answers
Answer:
[tex]\left \{ {{6x+4y=76} \atop {x+y=16}} \right.[/tex]
Step-by-step explanation:
1) if (according to the condition) the amount of quilting is 'x' and the amount of sateen is 'y', then the price of the quilting fabric is 6*x and the price of then sateen fabric is 4*y;
2) the 76$ she spends can be written as 6x+4y=76;
3) total of 16 yards can be written as x+y=16;
4) finally, the required system is:
[tex]\left \{ {{6x+4y=76} \atop {x+y=16}} \right.[/tex]
A system of equations is a collection of two or more equations with a same set of unknowns. 4x+6y=76, x+y=16 are required system of equations.
What is system of Equations?A system of equations is a collection of two or more equations with a same set of unknowns.
