Answer:

B. 16

Step-by-step explanation:

Solve for s:

$\longrightarrow$ 4(2s - 1) = 7s + 12

Expand out terms of the left hand side:

$\longrightarrow$ 8s - 4 = 7s + 12

Subtract 7 s from both sides:

$\longrightarrow$ (8s - 7s) - 4 = (7s - 7s) + 12

8s - 7s = s:

$\longrightarrow$ s - 4 = (7s - 7s) + 12

7s - 7s = 0:

$\longrightarrow$ s - 4 = 12

Add 4 to both sides:

$\longrightarrow$ s + (4 - 4) = 4 + 12

4 - 4 = 0:

$\longrightarrow$ s = 12 + 4

12 + 4 = 16:

$\longrightarrow$ s = 16

Valentin [98]

The best way to answer this would be making a graph

For 1 sign it costs 54.50 and he makes 15

For 2 signs it costs 59 and he makes 30

For 3 signs it costs 63.50 and he makes 45

For 4 signs it costs 68 and he makes 60

For 5 signs it costs 72.50 and he makes 75

This means that after 5 signs Larry will be making profit

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. B = 107°, a

Archy [21]

Answer: $105.19 \text{ square cm}$

Step-by-step explanation:

Since, by the SAS formula of finding the area of triangle,

The area of triangle, $A = \frac{1}{2}\times s_1\times s_2\times sin\theta$

Where, $s_1$ and $s_2$ are adjacent sides and $\theta$ is the included angle of these sides

Here, $s_1=22$ $s_2=10$

And, $\theta=107^{\circ}$

Thus, the area of the triangle ABC,

$A = \frac{1}{2}\times 22\times 10\times sin (107)^{\circ}$

$A = 110\times 0.95630475596$

$A = 105.193523156\approx 105.19\text { square cm}$

Therefore, Third Option is correct.

For 3 consecutive odd integers, the result of adding the smallest integer to four times the largest integer is 121. What are the

irakobra [83]

Answer: 21, 23, 25

Step-by-step explanation:

Let the integers be y, y+2 and y+4.

From the question, we are informed that the result of adding the smallest integer to four times the largest integer is 121. This can be mathematically expressed as:

y + 4(y+4) = 121

y + 4y + 16 = 121

5y + 16 = 121

5y = 121-16

5y = 105

y = 105/5

y = 21

Since y = 21,

y + 2 = 21 + 2 = 23

y + 4 = 21 + 4 = 25

The integers are 21,23 and 25
