Translate the sentence into an inequality.

1 answer:

7 0

For the difference of a number and 3, you should do b-3 and twice that would be 2(b-3). For this to be at most -23, the inequality would be ≤. Thus,

2(b-3)≤-23

is the answer.

Need help with favoring equations. First is m squared minus m minus six

sveticcg [70]

Answer:

(m − 3) (m + 2)

Step-by-step explanation:

m² − m − 6

To factor a quadratic ax² + bx + c, you can use the AC method.

1. Multiply a and c.

2. Find factors of ac that add up to b.

3. Divide the factors by a and reduce.

4. The denominators are the coefficients, the numerators are the constants.

Here, a = 1, b = -1, and c = -6.

1. ac = -6

2. Factors of -6 that add up to -1 are -3 and 2.

3. -3/1, 2/1

4. Factors are m − 3 and m + 2.

m² − m − 6 = (m − 3) (m + 2)

2/3(9a+18b)=6a+kb

bagirrra123 [75]

Answer:

4.) 12

Step-by-step explanation:

$\frac{2}{3} (9a + 18b) = 6a + kb \\ \\ \implies \: \frac{2}{3} \times 9a + \frac{2}{3} \times 18b = 6a + kb \\ \\ \implies \: { 6a} + 12b = 6a + kb \\ \\ \implies \: \cancel{ 6a} + 12b - \cancel{ 6a} = kb \\ \\ \implies \: 12b = kb \\ \\ \implies \: k = \frac{12\cancel b}{\cancel b} \\ \\ \huge \implies \: k = 12$

What would be the SA of a movie theater chair that was 49 in width, 28.7 in length and 39.6 in height in square feet

Naddika [18.5K]

Answer: $8966.44\ \text{square units}$

Step-by-step explanation:

Given

The dimension of the chair is

$\text{Width w= }49\ \text{units}\\\\\text{Length l= }28.7\ \text{units}\\\\\text{height h= }39.6\ \text{units}$

Suppose, the chair is in a rectangular shape, its Surface area is given by

$\Rightarrow SA=2[lw+wh+lh]\\\\\text{Insert the values}\\\\\Rightarrow SA=2[49\times 28.7+28.7\times 39.6+39.6\times 49]\\\\\Rightarrow SA=2[1406.3+1136.52+1940.4]\\\Rightarrow SA=2\times 4483.22\\\Rightarrow SA=8966.44\ \text{square units}$
