Answer 1

Step-by-step explanation:

the sum of the angles = 360

8x+2 + 2x + 14 + 3x -4 +5x + 5 = 360

18x +17 = 360

18x = 343

x = 19.1

angles are:

154.8

52.2 smallest (2x + 14)

53.3

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

4 x 6 is 24 and 4 x 7 is 28. 26 is between 24 and 28, so got to 24 since that is less than 26. 4 x 6 gets you 24, so 6 is your answer.

2y+3=5x-18. make x the subject​

Answers

[tex]x = \frac{2y + 21}{5} [/tex]

Step-by-step explanation:

1) Add 18 to both sides.

[tex]2y + 3 + 18 = 5x[/tex]

2) Simplify 2y + 3 + 18 to 2y + 21.

[tex]2y + 21 = 5x[/tex]

3) Divide both sides by 5.

[tex] \frac{2y + 21}{5} [/tex]

4) Switch sides.

[tex]x = \frac{2y + 21}{5} [/tex]

Hope it helps.

sorry if its wrong.

The equation 2y + 3 = 5x - 18 can be rearranged to make x the subject as x = (2y + 21) / 5.To make x the subject of the equation 2y + 3 = 5x - 18, we need to isolate x on one side of the equation.

Let's rearrange the equation step by step:

2y + 3 = 5x - 18

First, let's move the constant term (-18) to the other side by adding 18 to both sides:

2y + 3 + 18 = 5x

2y + 21 = 5x

Next, we can divide both sides by 5 to isolate x:

(2y + 21) / 5 = x

Therefore, the equation 2y + 3 = 5x - 18 can be rearranged to make x the subject as x = (2y + 21) / 5.

A pound of popcorn is popped for a class party. The popped corn is put into small popcorn boxes that each holds 120 popped kernels. There are 1,600 kernels in a pound of unpopped popcorn. If all the boxes are filled except for the last box, how many boxes are needed, and how many popped kernels are in the last partially filled box?

Answers

Answer:

14 ; 40

Step-by-step explanation:

Number of unpopped popcorn = 1600 kernels

Kernel per popped corn = 120

Number of boxes needed :

Number of unpopped / kernel per popped corn

1600 / 120

= 13.3333

Hence, number of boxes needed = 14

Number of popped kernel. In partially filled box :

1600 - (120 * 13)

1600 - 1560

= 40

Step-by-step explanation:

DeepSea Challenger’s descent was a change in depth of (-4) feet per second.We can use the equation y = -4x to model this relationship, where y is the depth (-35,814 ft) and x is the time in seconds that have passed. How many seconds does this model suggest it would take for DeepSea Challenger to reach the bottom?(round to the nearest tenth)
* Explain how you got your answer.

Answers

Answer:

Step-by-step explanation:

x = -35,814 ft ⋅ (1 sec)/(-4 ft) = 8,953.5 sec

The required model suggests that it would take approximately 8957.5 seconds for DeepSea Challenger to reach the bottom.

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

To find the time it takes for the DeepSea Challenger to reach the bottom, we need to find the value of x when y = -35,814 ft.

We can substitute the desired depth into the equation y = -4x:

-35,814 = -4x

35,814 = 4x

x = 35,814 / 4

x = 8953.5 seconds

So, the model suggests that it would take approximately 8957.5 seconds for DeepSea Challenger to reach the bottom.
