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:

[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.

To find :-

Solution :-

As we know that,

→ ₹1 = 100 p

So ,

→ 700p = ₹ 700/100

→ 700p = ₹ 7

Now let's calculate % , as ;

→ 700p / ₹7 * 100 %

→ ₹7/₹7 *100 %

→ 1 *100%

→ 100%

Hence 700p is 100% of ₹7 .

I hope this helps.

Step-by-step explanation:

We know that ,

1rupees = 100 paise

so , 7 rupees = 700 paise

We have to find the percentage of 700 paise of 7 rupees

Calculating Percentage ,

700paise/7rupees×100

7/7 × 100%

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

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:

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

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 %

Answer:

55w + 145

Step-by-step explanation:

Total = all accounts, so you have to add 10w to 45w, and 120 to 25

10w + 45w = 55w

120 + 25 = 145

So the answer is 55w + 145

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
