Answer 17

The expression can be simplified by combining like terms:

(4d - 3) + (12d + 4)
= 4d - 3 + 12d + 4
= (4d + 12d) + (-3 + 4)
= 16d + 1

So the simplified expression is 16d + 1.

Answer 18

To add the given expression, we need to find a common denominator for the fractions. The smallest common denominator for 2 and 4 is 4.

1/2 (x + 4) + 1/4 (4x - c2)
= (2/4)(x + 4) + (1/4)(4x - c2) (Multiplying the numerators by the same number we multiplied the denominators with)
= (2x + 8)/4 + (4x - c2)/4 (Combining the numerators)
= (2x + 8 + 4x - c2)/4 (Adding the fractions with common denominator)
= (6x + 8 - c2)/4 (Simplifying the numerator)

Since the fraction can be divided evenly by 2, we can simplify it further:

= (3x + 4 - c2/2)/2 (Dividing the numerator by 2)

Therefore, the simplified expression in mixed number form is:

= 3x/2 + 4/2 - c2/2 (Writing the expression with mixed numbers)
= 1 1/2x + 2 - c/2 (Converting the fraction to mixed number)

Answer 19

To add the given expression, we distribute the coefficients:

12(x + 4) + 14(4x - 2)
= 12x + 48 + 56x - 28 (Distributing the coefficients)
= 12x + 56x + 48 - 28 (Combining like terms)
= 68x + 20 (Simplifying)

Since the coefficient of x is a whole number, we can express the answer in mixed number form as:

= 68x + 20
= 68x + 20/1
= 68x + 20/1
= 68x + 20/1
= 68x + 20/1
= 68x + 20

Therefore, the simplified expression in mixed number form is 68x + 20.

Answer 20

To add the given expression, we need to find a common denominator for the fractions. The smallest common denominator for 2 and 4 is 4.

1/2(x + 4) + 1/4(4x - 2)
= (2/4)(x + 4) + (1/4)(4x - 2) (Multiplying the numerators by the same number we multiplied the denominators with)
= (2x + 8)/4 + (4x - 2)/4 (Combining the numerators)
= (2x + 8 + 4x - 2)/4 (Adding the fractions with common denominator)
= (6x + 6)/4 (Simplifying the numerator)

Since both the numerator and denominator can be divided evenly by 2, we simplify it further:

= (3x + 3)/2 (Dividing the numerator and denominator by 2)

Therefore, the simplified expression in mixed number form is:

= (3/2)(x) + (3/2) (Writing the expression with mixed numbers)
= 1 1/2x + 1 1/2 (Converting the fraction to mixed number)

Therefore, the answer in mixed number form is 1 1/2x + 1 1/2.

Answer 21

To add the given expression, we will combine like terms:

(2m - 3) + (3n - 1) + (3m + 1)
= 2m + 3n - 3 - 1 + 3m + 1
= (2m + 3m) + (3n) + (-3 + 1)
= 5m + 3n - 2

So the simplified expression is 5m + 3n - 2.

Answer 22

Apologies for the mistake. Let's correct the expression:

(2m - 3) + (3n - 1) + (3m + 1)

To add the expression, let's combine like terms:

2m + 3n - 3 - 1 + 3m + 1
= 2m + 3m + 3n - 3 + 1 + 1
= 5m + 3n - 1

Therefore, the correct simplified expression is 5m + 3n - 1.

Answer 23

Apologies once again for the mistake. Let's correct the expression:

(2m - 3) + (3n - 1) + (3m + 1)

To add the expression, let's combine like terms:

2m + 3n - 3 + 3m + 1
= (2m + 3m) + 3n + (-3 + 1)
= 5m + 3n - 2

Therefore, the correct simplified expression is 5m + 3n - 2.

Answer 24

To add the given expression, we combine like terms:

(2m - 3) + (3n - 1) + (3m + 1)
= 2m - 3 + 3n - 1 + 3m + 1
= (2m + 3m) + (3n) + (-3 - 1 + 1)
= 5m + 3n - 3

So the simplified expression is 5m + 3n - 3.

Answer 25

To subtract the given expression, we need to distribute the coefficient outside the parentheses:

2(10b + 4) - (b - 2)
= 2 * 10b + 2 * 4 - (b - 2)
= 20b + 8 - b + 2

Next, we combine like terms:

20b + 8 - b + 2
= 19b + 10

So, the simplified expression is 19b + 10.

Answer 26

To subtract the given expression, we need to distribute the coefficient outside the parentheses:

(3g - 4) - 2(3g + 4)
= 3g - 4 - 2 * 3g - 2 * 4
= 3g - 4 - 6g - 8

Next, we can combine like terms:

(3g - 6g) + (-4 - 8)
= -3g - 12

So, the simplified expression is -3g - 12.

Answer 27

To add the given expression using the properties of operations, we will distribute the coefficients:

9(k + 1/3) + 10(1/2k - 1)
= 9k + 9(1/3) + 10(1/2k) - 10(1)

Next, we simplify each term:

9k + 3 + 5k - 10
= (9k + 5k) + (3 - 10)
= 14k - 7

Therefore, the simplified expression is 14k - 7.

Answer 28

To add the given expression using the properties of operations, we will distribute the coefficients:

4(g - 2) + (g + 2)
= 4g - 8 + g + 2

Next, we combine like terms:

4g + g - 8 + 2
= 5g - 6

Therefore, the simplified expression is 5g - 6.

Answer 29

To subtract the given expression using the properties of operations, we will distribute the negative sign outside the second parentheses:

(h + k) - (2k - h)
= h + k - 2k + h

Next, we combine like terms:

(h + h) + (k - 2k)
= 2h + (-k)
= 2h - k

Therefore, the simplified expression is 2h - k.

Answer 30

To subtract the given expression using the properties of operations, we will distribute the negative sign outside the second parentheses:

(p - 3) - (2.4 + 2p)
= p - 3 - 2.4 - 2p

Next, we combine like terms:

(p - 2p) + (-3 - 2.4)
= -p - 5.4

Therefore, the simplified expression is -p - 5.4.

Answer 31

To subtract the given expression, we will distribute the coefficients outside the parentheses:

2(k - 4) - 3(2k - 1)
= 2k - 8 - 6k + 3

Next, we can combine like terms:

(2k - 6k) + (-8 + 3)
= -4k - 5

Therefore, the simplified expression is -4k - 5.
