-6+8x=-38
move -6 to the right of the exppression
it become 8 * x -6=-38
8* x -6+38=0
8* x -6 +32=0
Added fractions or integers together
It becomes 8*x +32=0
 8*x+32=0
Solved linear equation 8*x+32=0 equivalent to 8*x+32 =0
it becomes 0=0


This is an equation! Solutions X=-4

-6 +8x = -38
8x = -32
x = -4
I did this by first adding 6 to both sides to get 8x by itself. I then divided by 8 to get x by itself. I remembered to use the - - + rule (Two negatives make a positive, a positive and a negative make a negative). Hope this helps!

The Ross family had 100 relatives at their big Thanksgiving dinner of all the guest nine he had French heritage 80 had English h

il63 [147K]

Hi, Deedee. I am quite confused with the numbers that you've given because they don't add up to 100. Nevertheless, if by 'this', you mean the Thanksgiving culture, then you would just count the English and the Native American heritage. This is because the first Thanksgiving dinner was shared between the English colonists and the Native American tribes.

I hope I was able to help you in a way. Have a good day.

If a+b+c=0 for a,b,c then prove a²/bc+b²/ca+c²/ab=3.

Ierofanga [76]

According to the identity if a+b+c=0
then a3+b3+c3=3abc
a3+b3+c3/abc=3
a2*a/bc*a+b2*b/ca*b+c2*c/ab*c=3
cancel a,b,c in all the fraction then you get
a²/bc+b²/ca+c²/ab=3.
hence proved

The area of a circle is 43.25cm2. Find the length of the radius rounded to 2 DP.

Monica [59]

Answer:

3.71 cm

Step-by-step explanation:

Hi there!

Area of a circle equation: $A=\pi r^2$ where r is the radius

Plug in the area 43.25 cm²

$43.25=\pi r^2$

Divide both sides by π to isolate r²

$\frac{43.25}{\pi} =\frac{\pi r^2}{\pi} \\\frac{43.25}{\pi}=r^2$

Take the square root of both sides to isolate r

$\sqrt{\frac{43.25}{\pi}} =r\\3.71=r$

Therefore, the length of the radius rounded to 2 decimal points is 3.71 cm.

I hope this helps!
