Simplify a - {5b - [a - (3b - 2c) + c - (a - 2b -c. ]}.
-a - 6b + 4c
a - 6b + 4c
a - 10b + 4c
-a + 10b + 4c

Answers

Answer 1
Answer: ♥B)a - 6b + 4c

♥First you need to distribute the Negative Sign.

=a+−1(5b−(a−(3b−2c)+c−(a−2b−c)))

=a+−1(5b)+−1(−a)+−1(3b)+−1(−2c)+−1(−c)+−1a+−1(−2b)+−1(−c)

=a+−5b+a+−3b+2c+c+−a+2b+c

♥Now you need to Combine Like Terms:

=a+−5b+a+−3b+2c+c+−a+2b+c

=(a+a+−a)+(−5b+−3b+2b)+(2c+c+c)

=a+−6b+4c

♥and you get your final answer: a−6b+4c

Simplify the following expression.

Answers

Step-by-step explanation:      

Step 1: Simplify the equation

7.22−4.9(5.1+3.1)

=51.84−4.9(5.1+3.1)

=51.84−(4.9)(8.2)

Step 2: Solve and subtract the numbers

=51.84−40.18

=11.66

Explanation in words:

- To solve this equation, the first step is to simplify the equation and at the end, the answer will result as = 51.84-(4.9)(8.2).

- To solve this equation, the second step is to solve that equation and break it down so we will have to subtract and at the end, the answer for this whole equation will result as = 11.66.

Answer:      

= 11.66

A case of Mountain Dew (24cans) costs $7.68. What is the unit price?

Answers

Here are the unit rates involved:

$7.68 / 1 case  =  $7.68 per case

$7.68 / 24 cans  =  $0.32 per can

1 case / $7.68  =  0.13 case per $

24 cans / $7.68  =  3.125 cans per $

And of course ...

24 cans / 1 case  =  24 cans per case

1 case / 24 cans  =  0.041666... case per can

How to find the area of a circle ?

Answers


The area of a circle is π (Pi) times the Radius squared, which is written:
A = π × r2

Or, when you know the Diameter:


A = (π/4) × D2

Or, when you know the Circumference:


A = C2 / 4π

Answer:

Area of a circle = Aπr²

*You multiply the area by pi and then by the square of the radius.

**If you are given the diameter instead of the area then just divide it by 2 and substitute it in the expression.

***If you are given the circumference then: A = C²/ 4π

Answer:

10 = c

Step-by-step explanation:

Distribute -4 to the parentheses:

8 = 8c - 4(c + 8)

8 = 8c - 4c - 32

Add like terms:

8 = 4c - 32

Add 32 to both sides:

40 = 4c

10 = c

Answer:

Question:

8=8c-4(c+8)

Step-by-step explanation:

8=8c-4c-32

8=4c-32

8+32=4c

40=4c

Or

4c=40

c=10
