What is x in 3.6x=1.6x+24

Ipatiy [6.2K]

Answer:

x=12

Step-by-step explanation:

3.6x=1.6x+24

We simplify the equation to the form, which is simple to understand

3.6x=1.6x+24

We move all terms containing x to the left and all other terms to the right.

+3.6x-1.6x=+24

We simplify left and right side of the equation.

+2x=+24

We divide both sides of the equation by 2 to get x.

x=12

find the area of each sector. Use the 3.14 as the value of pi. Round your answer to the nearest tenth. Part 4

Yuri [45]

Answer:

1) 378.1 in²

2) 8.4 m²

Step-by-step explanation:

Area of sector= $\frac{θ°}{360°} \times \pi {r}^{2}$

1) Area of sector

$= \frac{150°}{360°} \times 3.14 \times {17}^{2} \\ = 378.1 \: in^{2} \\ (nearest \: tenth)$

2) Area of sector

$\frac{60°}{360°} \times 3.14 \times {4}^{2} \\ = 8.4 \: m^{2} \\ (nearest \: tenth)$

Answer:

<h2>Reflection.</h2>

Step-by-step explanation:

The image attached shows a representation of the problem, there you can observe the congruence between triangles.

Also, using the images you can easily deduct the transformation we need to map one triangle onto the other one, we just need to reflect one triangle across and axis that pass through point M, such line acts like a mirror.

Therefore, the right answer is reflection.
