-3÷3(a+c(b+5)-(-6+a)) use a=1 b= -6 and c= -4

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:

(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.

[tex]\\\implies y=-20+10\\\\\implies \boxed{y=-10}[/tex]

The solution to the system of equations is (5, -10).

Answer:

  explanation:

solving similarities:

bigger triangle is double of the smaller triangle.

balancing them:

→ x + 9 = 2(2x - 3)

→ x + 9 = 4x - 6

→ 4x - x = 9 + 6

→ 3x = 15

→ x = 5

[tex]→x + 9 = 2(2x - 3)[/tex]

[tex]→x + 9 = 4x - 6[/tex]

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 %

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.

[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.

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: 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

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
