2
3

(80+4
2
)
​

Answer 1

To evaluate the expression \( \frac{(80 + 4^2)}{2^3} \), we will follow these steps:

1. **Calculate \( 4^2 \)**:
\[
4^2 = 16
\]

2. **Add \( 80 \) and \( 16 \)**:
\[
80 + 16 = 96
\]

3. **Calculate \( 2^3 \)**:
\[
2^3 = 8
\]

4. **Now divide \( 96 \) by \( 8 \)**:
\[
\frac{96}{8} = 12
\]

So, the value of the expression is \( 12 \).

Answer 2

What is the value of the expression start fraction, left parenthesis, 8, squared, minus, 56, right parenthesis, divided by, 2, cubed, end fraction

(8
2
−56)
​

Answer 3

To evaluate the expression \( \frac{(8^2 - 56)}{2^3} \), we can follow these steps:

1. **Calculate \( 8^2 \)**:
\[
8^2 = 64
\]

2. **Subtract \( 56 \) from \( 64 \)**:
\[
64 - 56 = 8
\]

3. **Calculate \( 2^3 \)**:
\[
2^3 = 8
\]

4. **Now divide \( 8 \) by \( 8 \)**:
\[
\frac{8}{8} = 1
\]

So, the value of the expression is \( 1 \).

Answer 4

What is the value of the expression start fraction, left parenthesis, 75, plus, 5, squared, right parenthesis, divided by, 5, squared, end fraction
5
2

(75+5
2
)

Answer 5

To evaluate the expression \(\frac{(75 + 5^2)}{5^2}\), we can follow these steps:

1. **Calculate \(5^2\)**:
\[
5^2 = 25
\]

2. **Add \(75\) and \(25\)**:
\[
75 + 25 = 100
\]

3. **Now divide \(100\) by \(25\)**:
\[
\frac{100}{25} = 4
\]

So, the value of the expression is \(4\).

Answer 6

What is the value of the expression below when w, equals, 4w=4?
9, w, minus, 10
9w−10

Answer 7

To evaluate the expression \(9w - 10\) when \(w = 4\), we can substitute \(4\) for \(w\):

1. Substitute \(w\) in the expression:
\[
9(4) - 10
\]

2. Calculate \(9 \times 4\):
\[
9 \times 4 = 36
\]

3. Now subtract \(10\) from \(36\):
\[
36 - 10 = 26
\]

So, the value of the expression \(9w - 10\) when \(w = 4\) is \(26\).

Answer 8

What is the value of the expression below when y, equals, 5y=5?
8, y, plus, 10
8y+10

Answer 9

To evaluate the expression \(8y + 10\) when \(y = 5\), substitute \(5\) for \(y\):

1. Substitute \(y\) in the expression:
\[
8(5) + 10
\]

2. Calculate \(8 \times 5\):
\[
8 \times 5 = 40
\]

3. Now add \(10\) to \(40\):
\[
40 + 10 = 50
\]

So, the value of the expression \(8y + 10\) when \(y = 5\) is \(50\).

Answer 10

What is the value of the expression below when y, equals, 8y=8?
2, y, minus, 3
2y−3

Answer 11

To evaluate the expression \(2y - 3\) when \(y = 8\), we substitute \(8\) for \(y\):

1. Substitute \(y\) in the expression:
\[
2(8) - 3
\]

2. Calculate \(2 \times 8\):
\[
2 \times 8 = 16
\]

3. Now subtract \(3\) from \(16\):
\[
16 - 3 = 13
\]

So, the value of the expression \(2y - 3\) when \(y = 8\) is \(13\).
