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.

A system of equations is a collection of two or more equations with a same set of unknowns.

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 4x and the price of then sateen fabric is 6y;

the 76$ she spends can be written as 4x+6y=76;

Total of 16 yards can be written as x+y=16;

So the required system of Equations is:

4x+6y=76

x+y=16

Hence Option C is correct. 4x+6y=76, x+y=16.

the answer is: 31/9=3.4444≈3.4

The relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.

The relative frequency of an event is the ratio of total number of favorable or desired outcome to the total number of trails done.

Given information-

The card is selected random from the deck of cards.

Total number of trails is 40.

It is known that the total number of diamond card in a standard deck of card is 11. There is total 40 trials is done in which a random card is selected.

As the relative frequency is the ratio of total number of diamonds to the total number of trials done. Thus,

[tex]f_r=\dfrac{11}{40}\\f_r=0.3[/tex]

In the percentage from,

[tex]f_r={0.3}\times100\\f_r=30[/tex]

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

Answer:

(5, -10)

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}y=-4x+10&\\y=-3x+5\end{cases}[/tex]

Substitute the first equation into the second:

[tex]\implies -3x+5=-4x+10[/tex]

SOLVING FOR X.

Step 1: Add 4x to both sides.

[tex]\\\implies-3x+4x+5=-4x+4x+10\\\\\implies x+5=10[/tex]

Step 2: Subtract 5 from both sides.

[tex]\\\implies x+5-5=10-5\\\\\implies \boxed{x=5}[/tex]

SOLVING FOR Y.

Step 1: Substitute [tex]x=5[/tex] into any of the given equations.

[tex]\\\implies y=-4(5)+10[/tex]

Step 2: Simplify.

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

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

Says so on edge

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

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.

Answer:

60%

Step-by-step explanation:

5-8/5 * 100%= 60%

The percentage change from 5 to 8 is given by A = 60 %

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 %
