Can someone tell me if this right or wrong

Answer:

The cost price is $395.74 or  $446.26

Step-by-step explanation:

When we do 421 times 0.06 (same thing as 6%) we get 25.26

We subtract 25.26 from 421 we get $395.74

If we add 25.26 to 421 we get  $446.26

Answer:

-1/10, 2/10, and 4/10

Step-by-step explanation:

A rational number is a number that is in the form of p/q, where p and q are integers, and q is not equal to 0.

First, what is the lcm of 5 and 2? the lcm is 10, because that is the lowest number than can be divided separately by 5 and 2 and the results would still be a whole number.

We now need to find 3 rational numbers between -2/10 and 5/10. It's easy now that I've explained it, right?

-1/10, 2/10, and 4/10 are between -1/5 and 1/2 and are integers with the given explanation.

Hope this helps.

circumference equals diameter, aka 2r, times 3.14, aka pi

have a good day friend :)

Explanation:

There are 6 blocks across the width, 3 blocks along the height, and 2 blocks along the depth.

The volume is 6*3*2 = 18*2 = 36 cubic inches. In other words, there are 36 small blocks that make up this bigger 3D solid.

Step-by-step explanation:

Answer:  (-2, 8)

Explanation:

Plug x = -2 into the second equation. Isolate y.

5x+3y = 14

5(-2)+3y = 14

-10+3y = 14

3y = 14+10

3y = 24

y = 24/3

y = 8

We have x = -2 lead to y = 8.

Therefore, the ordered pair (x,y) = (-2,8) is the solution to this system.

Answer:

  (c)  Similar by AA~

Step-by-step explanation:

The outside segments are marked parallel, so the angles formed where the transversals meet them are congruent. That is ∠CBD ≅ ∠EDB, and ∠CED ≅ ∠ECB. (The vertical angles where the lines cross are congruent, as well.)

So, the angles in one triangle are congruent to the angles in the other triangle. The triangles are similar by the AA~ postulate.

Answer: 2 over 1

Step-by-step explanation:

1+1=2

However we want this as a fraction

Any whole number as a fraction is just over one

Therefore the final answer is 2 over 1

You’re welcome Kaeya!

Answer: it’s 2 over 1 mate

Step-by-step explanation: you’re welcome

[tex] \huge \boxed{ \tt x = 83 {}^{\circ} }[/tex]

x + 47 + 50 = 180 (sum of angles of triangle = 180°)

x + 97 = 180°

x = 180° -97

x = 83 °

Answer:

Step-by-step explanation:

12 3/4- 5 1/2

Answer:

9/9/108/126

Step-by-step explanation:

1/2bh is how you find the area of a triangle ! :)

This means that for both triangles, the area is 2 times the height, 9, then multiplied by one half. The area is 9 for both the left and right triangle.

The area of the rectangle is the product of the two lengths: 9 and 12, which is 108.

This means that the area of the entire trapezoid is 126.   :D

» Twice a number is 500 more than six times the number. What is the number?

— — — — — — — — — —

Let the number be x.

Then,

[tex]2x = 6x + 500 \\ 2x - 6x = 500 \\ \: \: \: \: \: \: \: - 4x = 500 \\ \: \: \: \: \: \: \: \: \frac{ \cancel{- 4}x}{ \cancel{- 4}x} = \frac{500}{ - 4} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = \underline{ \boxed{ \blue{ - 125}}}[/tex]

Hence, the number is -125.

Using algebraic expression, the number is calculated as: -125.

An algebraic expression involves using numbers and variables to make statements.

Let the unknown number be represented as x. Therefore:

Twice the number is 2x

2x is 500 more than 6x is 2x = 6x + 500

Solve the algebraic equation to find the number (x):

2x = 6x + 500

2x - 6x = 500

-4x = 500

x = -500/4

x = -125

Thus, using algebraic expression, the number is calculated as: -125.

Answer:

D. 15

Step-by-step explanation:

I assume you know what pascal's triangle is if this is the work you must complete. If not, I have attached it below.

Now, raising (a+b) to the 6th term would expand to this, based on Pascal's triangle

[tex]\left(a+b\right)^6 = \quad a^6+6a^5b+15a^4b^2+20a^3b^3+15a^2b^4+6ab^5+b^6[/tex]

Remember that terms are separated by addition or subtraction symbols.

The 5th term of this 7 term expansion would be 15a^2b^4. The coeffecient is 15 in this case.

Answer:

x = 2 and y = 3

Step-by-step explanation:

given:

using elimination rule:

 2x - 3y = -5

- 2x - y = - 7

................................

-4y = -12

y = 3

Find x:

2x - 3y = -5

2x - 3(3) = -5

2x - 9 = -5

2x = - 5+9

2x = 4

x = 2

Step-by-step explanation:

[tex](2x-3y)-(2x+7)\\=-4y=(-5)-(7)\\-4y=-12\\y=12/4\\y=3[/tex]

Insert y=3 into any one equation in the system of equations:

[tex]2x-3(3)=-5\\2x-9=-5\\2x=4\\x=4/2\\x=2[/tex]

or

[tex]2x+(3)=7\\2x=4\\x=4/2\\x=2[/tex]

Answer:

4x-2y=-1  multiply by 3

5x-3y=7  multiply by 3

12x+6y=-3

10x-6y=14  add them

so =22x=11

   x=1/2

5(1/2)-3y=7

2.5-3y=7 take 2.5 to the other side

-3y=4.5

y=-3/2  

therefore x=1/2 and y=-3/2

Answer:

The top is independent

The bottom is dependent

Step-by-step explanation:

     The top is independent because it does not rely on another variable. It is the "affector" and not dependent on it.

     The bottom is dependent because it does rely on another variable. It is dependent on this other variable because it will be affected by any changes in that other variable.

Answer:

x = 3/2 | y = -3

Step-by-step explanation:

Given equations:

Substituting from equation (i) for y:

==> 2x - 6 = -4x + 3

==> 2x + 4x = 6 + 3

==> 6x = 9

dividing both sides by 3:

==> 2x = 3

==> x = 3/2

Substituting 3/2 for x in equation (i):

==> y = 2(3/2) - 6

==> y = 3 - 6

==> y = -3

[tex] - 4x + 3 = 2x - 6 \\ 6x = - 9 \\ 2x = - 3 \\ x = - 1.5[/tex]
