Question

Evaluate the expression for c = 6 and d = 5.

c + d =

Answer 1

To evaluate the expression \( c + d \) for \( c = 6 \) and \( d = 5 \), simply substitute the values into the expression:

\[ c + d = 6 + 5 = 11 \]

So, \( c + d = 11 \).

Answer 2

Evaluate the expression for h = 3 and j = 5.

h + j =

Answer 3

To evaluate the expression \( h + j \) for \( h = 3 \) and \( j = 5 \), substitute the values into the expression:

\[ h + j = 3 + 5 = 8 \]

So, \( h + j = 8 \).

Answer 4

Evaluate the expression for f = 4 and g = 5.

fg =

Answer 5

To evaluate the expression \( fg \) for \( f = 4 \) and \( g = 5 \), substitute the values into the expression:

\[ fg = 4 \times 5 = 20 \]

So, \( fg = 20 \).

Answer 6

Evaluate the expression for h = –5 and j = 11.

h − j =

Answer 7

To evaluate the expression \( h - j \) for \( h = -5 \) and \( j = 11 \), substitute the values into the expression:

\[ h - j = -5 - 11 \]

Calculating this gives:

\[ h - j = -5 - 11 = -16 \]

So, \( h - j = -16 \).

Answer 8

Evaluate the expression for r = –6 and s = 3.

–rs =

Answer 9

To evaluate the expression \( -rs \) for \( r = -6 \) and \( s = 3 \), substitute the values into the expression:

\[ -rs = -(-6)(3) \]

Calculating \( rs \):

\[ rs = (-6)(3) = -18 \]

Now, applying the negative sign:

\[ -rs = -(-18) = 18 \]

So, \( -rs = 18 \).

Answer 10

Evaluate the expression for s = –3 and t = 6.

st =

Answer 11

To evaluate the expression \( st \) for \( s = -3 \) and \( t = 6 \), substitute the values into the expression:

\[ st = (-3)(6) \]

Calculating this gives:

\[ st = -18 \]

So, \( st = -18 \).
