==> False.

This statement is false. To solve the system by substitution, replace y in the first equation with 7−6x.

==> False

This statement is false. To solve the system by substitution, replace y in the second equation with 6x−7.

==> True.

From the first equation, 6x-y=7

y= 6x-7

Answer: This statement is false. To solve the system by​ substitution, replace y in the second equation with 6x−7.

Answer:

a) I don't know sorry

b) i think 2,25km but i'm not sure

Step-by-step explanation:

1:25 000 cm

1:25 00 dm

1:250 m

1:0,025 km

9.250=2250

2,25

Answer:

x > 90

Step-by-step explanation:

To solve this, we will use the multiplication property of equality. We need to multiply both sides by 6, this will get us x > 90.

Answer:

Number of extra boxes= 120

Step-by-step explanation:

Giving the following information:

Batteries per box= 50

Number of batteries= 18,000

Number of batteries in ecxess= 6,000

We need to calculate the number of boxes required to cover the 6,000 extra batteries:

Number of extra boxes= number of batteries / batteries per box

Number of extra boxes= 6,000 / 50

Number of extra boxes= 120

=====================================

Work Shown:

EI = EG

3y-10 = 2y

3y-10-2y = 0

y-10 = 0

y = 0+10

y = 10

Note how if y = 10, then

Both EI and EG are 20 units long when y = 10. This confirms the answer.

Answer:

-6 is the missing value.....

Answer:

(-6, 8); the missing value is -6

Step-by-step explanation:

First, you need to solve the given equation for x

1: 2x + 3y = 12 (Given)

2: 2x = -3y + 12 (Subtract 3y from both sides to isolate x)

3: x = -1.5y + 6 (Divide both sides by 2)

Now, you can solve for the missing x in the solution set (x, 8):

where x = -1.5y + 6 and y = 8,

x = -1.5(8) + 6

x = -12 + 6

x = -6

So, the missing value is -6

Answer:

2h+7j+2

Step-by-step explanation:

9h-7h=2

the 7j has nothing to add or subtract

the 2 is a -(-2) so you'd add it.

Step-by-step explanation:

-5x + 4y = 2

+ (9x - 4y = 6)

=> 4x = 8, x = 2.

Therefore -5(2) + 4y = 2, 4y = 12, y = 3.

The solution pair is (2,3).

Answer:

5

Step-by-step explanation:

Answer:

1/2w = 10 (you have to divide both sides by 1/2 to isolate w)

w= 5 (your answer)

I hope this helped :)

Answer:

Well thats pretty easy. the answer is non-determineable

Step-by-step explanation:

prove me wrong

The solution for pi is π = 2A/r² where r is the radius.

The area of a circle is defined as the space occupied by the circle in a two-dimensional plane. In other word, the space occupied under the region or circumference of a circle is called the area of the circle.

The formula for the area of a circle is A = πr²,

Where r is the radius of the circle.

For example, if the radius of circle is 6cm, then its area will be: Area of a circle with 6 cm radius = πr² = π(6)² = 36π square cm.

Given data as :

A = 1/2 πr²

Solve for pi

⇒ A = 1/2 πr²

Multiply by 2 both the side

⇒ 2A =  πr²

⇒ 2A/r² =  π  or

⇒  π = 2A/r²

If A = 76 cm² and π  = 22/7,

⇒ A = πr²

⇒ A/π = r²

⇒ √A/π = r

Substitute the values, we have:

⇒ √76 /(22/7) = r

⇒ √76 * 7/22 = r

⇒ √532/22 = r

⇒ √24.1818 = r

⇒ 4.917 = r

⇒ r = 4.92 cm (Rounding to two decimal places)

The question seems to be incomplete the correct question would be

If A = 76 cm² and π  = 22/7, what is the value of r in centimeters?

The radius would be 2.2281 or 7/π

Answer:

[tex]x=4\sqrt{2}[/tex]

Step-by-step explanation:

The given triangle is a 45°-45°-90° triangle. Use the following rule:

[tex]leg=leg\\\\hypotenuse=leg*\sqrt{2}[/tex]

The length of the legs is 4. Insert this value into the equation:

[tex]h=4*\sqrt{2}[/tex]

Simplify:

[tex]h=4\sqrt{2}[/tex]

−576n⁴-1152x⁵

Answer:

Part A)

Height = 19.3 feet

Part B)

Distance = 5.2 feet

Step-by-step explanation:

Part A)

Let ladder reaches upto the h height of the wall.

[tex] \therefore \sin \theta =\frac{h}{length\: of\: the \:ladder} [/tex]

[tex] \therefore \sin 75\degree =\frac{h}{20} [/tex]

[tex] \therefore 0.9659258263 =\frac{h}{20} [/tex]

[tex] \therefore 0.9659258263\times 20 = h [/tex]

[tex] \therefore 19.3185165 \: ft= h [/tex]

[tex] \therefore h = 19.3 \: ft= h [/tex]

Part B)

Let the distance from the wall to the base of the ladder be x feet.

[tex] \therefore \cos \theta =\frac{x}{length\: of\: the \:ladder} [/tex]

[tex] \therefore \cos 75\degree =\frac{x}{20} [/tex]

[tex] \therefore 0.2588190451 =\frac{x}{20} [/tex]

[tex] \therefore 0.2588190451\times 20 = x [/tex]

[tex] \therefore 5.1763809 \: ft= x [/tex]

[tex] \therefore x = 5.2 \: ft [/tex]
