2x+12=6x-12 show all work

Mathematics
1 answer:
kenny6666 [7]3 years ago
6 0
First off we want to combine "like-terms"
1. Subtract 6x , so it will look like this: 2x-6x+12=-12
2. Subtract the -12 from the first side so it looks like 2x-6x=-12-12
3. Combine like terms. So: -3x=-24 . The negatives will cancel out when dividing 24/3.

The final answer is 8 after dividing. Hope this helped!

Erica is making feathered caps for her school play. Each cap must have 3 feathers. Write an equation that represents the number
FrozenT [24]

Answer:

f=3c

Step-by-step explanation:

Given:

Number of feathers = f

Number of caps = c

Number of feathers in each cap = 3

Now, solving by setting up a proportion.

1 cap has 3 feathers. 'c' caps has 'f' feathers.

This gives,

\dfrac{1}{3}=\dfrac{c}{f}

Solving by cross multiplication, we get:

1\times f=3\times c\\\\f=3c

Therefore, the equation representing the number of feathers 'f' Erica needs to make 'c' caps is given as:

f=3c

The length of a will be a different number and the value will be 4.71in

<h3>How to find the area of a sector</h3>

The given diagram is a sector and the formula for calculating the length of an arc is expressed as:

Length of an arc = rβ

where

  • β is the subtended angle
  • r is the radius

Given the following parameters

β .= 45 degrees

r = 6in

Substitute

Length of an arc = 6π/4

Length of an arc = 6(3.14)/4

Length of an arc = 4.71inches

This shows that the length of a will be a different number and the value will be 4.71in
