Combine like terms in -6 x + x.

x - 6 x = -5 x:

Answer:  -5 x

Answer:

12π meters

Step-by-step explanation:

Area of circle = Pi*r^2 -> 36*Pi = Pi*r^2

So, radius of circle (r) = 6 m

Circumference of circle = 2*Pi*r = 2*Pi*6 = 12Pi m

Answer:

D) y = 4

Step-by-step explanation:

It is a horizontally straight line, meaning it is parallel to the x-axis.

Answer:

No , because The Pythagorean equation isn't true.

Step-by-step explanation:

a² = b² + c²

14² = 11² + 8²

196 = 121 + 64

196 ≠ 185

Answer:

There are infinate solutions.

Step-by-step explanation:

Plug (3x-8) in for y

5(3x-8)=15x-40

Simplify

15x-40=15x-40

Explanation:

If we multiply both sides of the second equation by 5, then we go from y = 3x-8 to 5y = 15x-40. This is exactly identical to the first equation of the system.

Therefore, the two equations are equivalent just in slightly different forms. The two equations graph the same line which leads to infinitely many solutions.

The solutions are of the form (x, 3x-8) where x is any real number.

Since there are infinitely many solutions, we consider this system to be dependent.

Answer:

63

Step-by-step explanation:

6² + 3³

= 36 + 27

= 63

Answer:

63. Six times six is thirty six. Three times three times three is twenty seven. Thirty six plus twenty seven is equals to sixty-three

Step-by-step explanation:

=6²+3³

=36+27

=63

Answer:

£40:£30

Step-by-step explanation:

As we can see the ratio adds up to 7 since:

4+3=7

So now we know 1 share of the ratio will be:
£70÷7=£10

So 4 shares is £40 and 3 shares is £30

Step-by-step explanation:

derivative:zero becouse ever number has daritive is zero

Step-by-step explanation:

10+4+2π I think!!!

Answer:

A. 5:4

Step-by-step explanation:

There are 10 girls and 8 boys, so the ratio of girls to boys would be 10:8. BUT we are going to simplify it. 10 and 8 both can be divided by 2, so we get a ratio of 5:4.

Answer:

[A] 5:4

Step-by-step explanation:

There are 8 boys and 10 girls.

What is the ratio of girls to boys in Mrs. Nathan's class?

10:8 is the ratio

As you can see that not a answer choice.

That cause you have to simplify.

Find the GCF. [2]

Hence, 10:8 both divide by 2

= 5:4

Thus, Answer = [A] 5:4

Answer:

w = 7

Step-by-step explanation:

Divide both sides of the equation by the same term

[tex]\frac{28}{4}=\frac{4w}{4}[/tex]

Simplify

w = 7

Answer:

5 < third side < 21

Step-by-step explanation:

Let the length of the third side be [tex]x[/tex].

We know that [tex]x[/tex] must be smaller than the sum of the lengths of the two other sides. Thus [tex]x < 21[/tex].

We also know that

[tex]x+8 > 13\\x > 5[/tex]

And

[tex]x+13 > 8\\x > -5[/tex]

So, in conclusion, [tex]5 < x < 21[/tex].

Answer:

(1, -4)

Step-by-step explanation:

In this system, multiply the top equation by -4. this will give you

-4x - 12y = 44

4x + 7y = -24

the x values can now cancel out, and add the other values together

-5y = 20

y = -4

now, substitute y = -4 in for one of the starting equations

x + 3(-4) = -11

x - 12 = -11

x = 1

Answer:

Multiply the numerator by the reciprocal of the denominator. Multiply x x by 1 1 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=1x f - 1 ( x ) = 1 x is the inverse of f(x)=1x f ( x ) = 1 x .

Step-by-step explanation:

Given:

The rule is telling us to add 7 to the given value of x.

Add 7 to 12.

[tex]7 + 12 = 19[/tex]

The missing number is 19.

Answer:

(x+5)^2+(y-8)^2=4^2

Step-by-step explanation:

I used a website called desmos.

Answer:

(x + 5)² + (y - 8)² = 16

Step-by-step explanation:

the equation of a circle in standard form is

(x - h )² + (y - k )² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (- 5, 8 ) and r = 4 , then

(x - (- 5) )² + (y - 8)² = 4² , that is

(x + 5)² + (y - 8)² = 16

Answer:

175/48

Step-by-step explanation:

Convert 8 6/8 and 2 2/5 to fractions
8 6/8 = 70/8 ; 2 2/5 = 12/5

Now, we have : 70/8 : 12/5
= 70/8 x 5/12
= 70x5/8x12

=350/96
Simplify the fraction, we get 175/48

Answer:

B

Step-by-step explanation:

Divide 243.46 by 37 to solve for t

Step-by-step explanation:

37t means 37 x t. We are solving for t.

First, we need to divide 243.46 by 37.

243.46÷37=6.58

t=6.58

Now we need to check and make sure our answer is correct.

Since we are solving for t, we need to multiply 37 by 6.58 to make sure our answer is correct.

37 x 6.58= 243.46. We got 243.46 which means it is correct.
