3c/4 - 2c/4 = 4 (solve with work please)

Mathematics
1 answer:
xxMikexx [17]3 years ago
3 0

Simplifying

2c + 3 = 3c + -4

Reorder the terms:

3 + 2c = 3c + -4

Reorder the terms:

3 + 2c = -4 + 3c

Solving

3 + 2c = -4 + 3c

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-3c' to each side of the equation.

3 + 2c + -3c = -4 + 3c + -3c

Combine like terms: 2c + -3c = -1c

3 + -1c = -4 + 3c + -3c

Combine like terms: 3c + -3c = 0

3 + -1c = -4 + 0

3 + -1c = -4

Add '-3' to each side of the equation.

3 + -3 + -1c = -4 + -3

Combine like terms: 3 + -3 = 0

0 + -1c = -4 + -3

-1c = -4 + -3

Combine like terms: -4 + -3 = -7

-1c = -7

Divide each side by '-1'.

c = 7

Simplifying

c = 7

Your answer would be "D", because when finding the GCF of a term, you want to take the most out of it. Following the procedure of D, finding the greatest shared factor of 10 and 15 and the greatest shared power between exponent 2 and exponent 3, would allow you to find the GCF.

vlabodo [156]
2/5(x - 4) = 2x
2/5x - 8/5 = 2x....multiply everything by 5
2x - 8 = 10x
-8 = 10x - 2x
-8 = 8x
-8/8 = x

there are 118 boys and 121 girls signed up for a volleyball league. The coaches first make teams of 9 players and then assign an
andrew11 [14]

The number of nine-players team= 21 teams.

The number of ten-players team= 5 teams.

<u>Step-by-step explanation:</u>

<u>step 1:</u> The total players signed up for a volleyball league= 118 boys+121 girls= 239 players.

<u>step 2:</u> The coach first makes a 9 players team= 239-9= 230 members

In this stage, the number of 9 players-team is one.

<u>step 3:</u> The remaining 230 players cannot be divided equally into 9 players, since 230 is not divisible by 9.

<u>step 4:</u> Find the number within 230 that is divisible by 9 as a whole. Check for easy number (9*20= 180 is within 230)

Therefore, 230-180= 50 players are remaining.

In this stage, the number of 9 players-team= 1+20= 21 teams with 9-players.

The number of 10 players-team= 50 players/10= 5 teams with 10-players.
