GPT-4o mini · Answer

To simplify the expression $ \frac{9}{3}x + 4 + 2x $, we can follow these steps: 1. Simplify $ \frac{9}{3}x $: $$ \frac{9}{3}x = 3x $$ 2. Now, substitute that back into the expression: $$ 3x + 4 + 2x $$ 3. Combine the like terms ($3x$ and $2x$): $$ (3x + 2x) + 4 = 5x + 4 $$ Thus, the simplified expression is $ 5x + 4 $. The correct response is: **5x + 4**.

Simplify the expression. (5y−1)+(−2y+4) (1 point)

GPT-4o mini · Answer

To simplify the expression $ (5y - 1) + (-2y + 4) $, we can follow these steps: 1. Remove the parentheses: $$ 5y - 1 - 2y + 4 $$ 2. Combine like terms: - Combine the terms with $y$: $5y - 2y = 3y$ - Combine the constant terms: $-1 + 4 = 3$ 3. Write the simplified expression: $$ 3y + 3 $$ Thus, the simplified expression is $ 3y + 3 $.

GPT-4o mini · Answer

To simplify the expression $ (h + 12) + (p + 24) $, we can follow these steps: 1. Remove the parentheses: $$ h + 12 + p + 24 $$ 2. Combine like terms (the constants): $$ 12 + 24 = 36 $$ 3. Rewrite the expression: $$ h + p + 36 $$ Thus, the simplified expression is $ h + p + 36 $. The correct response is: **h + p + 36**.

GPT-4o mini · Answer

To simplify the expression $ \left( \frac{3}{4}x - 1 \right) + \left( \frac{3}{4}x - 2 \right) $, follow these steps: 1. Remove the parentheses: $$ \frac{3}{4}x - 1 + \frac{3}{4}x - 2 $$ 2. Combine like terms: - Combine the terms with $x$: $$ \frac{3}{4}x + \frac{3}{4}x = \frac{6}{4}x = \frac{3}{2}x $$ - Combine the constant terms: $$ -1 - 2 = -3 $$ 3. Write the simplified expression: $$ \frac{3}{2}x - 3 $$ Thus, the simplified expression is $ \frac{3}{2}x - 3 $. The correct response is: **$\frac{3}{2}x - 3$**.

Simplify the expression. 7x+3(x−2)−4x+8 (1 point) Responses 6x+14 6 x plus 14 6x+2 6 x plus 2 14x+2 14 x plus 2 14x+14

GPT-4o mini · Answer

To simplify the expression $ 7x + 3(x - 2) - 4x + 8 $, follow these steps: 1. Distribute the $3$ to the terms inside the parentheses: $$ 7x + 3x - 6 - 4x + 8 $$ 2. Combine like terms: - Combine the $x$ terms: $$ 7x + 3x - 4x = (7 + 3 - 4)x = 6x $$ - Combine the constant terms: $$ -6 + 8 = 2 $$ 3. Write the simplified expression: $$ 6x + 2 $$ Thus, the simplified expression is $ 6x + 2 $. The correct response is: **6x + 2**.

Simplify the expression. (3x−8)+(2x+5)−(4x−8) (1 point) Responses 9x−11 9 x minus 11 x+5 x plus 5 9x+5 9 x plus 5 x−11

GPT-4o mini · Answer

To simplify the expression $ (3x - 8) + (2x + 5) - (4x - 8) $, follow these steps: 1. Remove the parentheses: $$ 3x - 8 + 2x + 5 - 4x + 8 $$ 2. Combine like terms: - Combine the $x$ terms: $$ 3x + 2x - 4x = (3 + 2 - 4)x = x $$ - Combine the constant terms: $$ -8 + 5 + 8 = -8 + 13 = 5 $$ 3. Write the simplified expression: $$ x + 5 $$ Thus, the simplified expression is $ x + 5 $. The correct response is: **x + 5**.
