Hey there!

7 < 5x + 2 < 22
Let's start by adding -2 to both sides
7 - 2 < 5x + 2 - 2 < 22 - 2
5 < 5x < 20
Then divide each part by 5 :)
5/5 < 5x < 20/5
1 < x < 4


I hope this helps. Please let me know if you have questions about the answer.
Down bellow is the graph.

Best of luck with your studies!

Nathan launches a water balloon vertically from a platform on his roof. The height of the balloon (in feet) is represented by th
bulgar [2K]

Answer:

45.27feet

Step-by-step explanation:

Given the height of the balloon (in feet) represented by the equation h=−16t2+28.7t+32.4, where t is the time (in seconds)

Note that the velocity of the balloon at maximum height is zero, hence;

v = dh/dt =0

-32t+28.7 = 0

-32t = -28.7

t = 28.7/32

t = 0.897secs

Get the maximum height

Recall that h=−16t²+28.7t+32.4

h = -16(0.897)²+28.7(0.897)+32.4

h= -12.87+25.74+32.4

h = 45.27feet

Hence the maximum height reached is 45.27feet

Triangle A:B:C is 5:4:3​
Nitella [24]

Answer: the angles are: 30, 45, 75

Step-by-step explanation:

the sum of the angles of a triangle is 180 degrees.

the angles are in a ratio of 3:4:5.

if you allow the number of degrees in the first angles to be 3x, this means that the number of degrees in the second angle is equal to 4x and the number of degrees in the third angle is equal to 4x.

since the sum of the angles in a triangle is equal to 180 degrees, this means that:

3x + 4x + 5x = 180 degrees which means that 12x = 180.

divide both sides of this equation by 12 and you get x = 180 / 12 = 15 degrees.

this means that the 3x angles is equal to 45 degrees and the 4x angle is equal to 60 degrees and the 5x angle is equal to 75 degrees.

45 + 60 + 75 = 180 degrees so we're good there.

45 / 60 is equal to 3/4

60 / 75 is equal to 4/5

the angles are in the ratio of 3 to 4 to 5 which is as originally assumed, so we're good all around and that's your answer.

the angles are:

30, 45, 75

the ratio of 3:4:5 means that:

the first angle is in a ratio of 3/4 with the second angle.

the second angle is in a ratio of 4/5 with the third angle.

the first angle is in a ratio of 3/5 with the third angle.

the ratio of the first angle with the third angle is equal to 45/75.

simplify that by dividing both numerator and denominator by 15 and you get 3/5.

o-na [289]

What is ocean expansion:

Eustatic change is the expansion of the ocean due to the addition of water. The extra amount of water released into the ocean body is due to melting ice sheets and glaciers. Warmer temperatures accelerates the melting, adding more water into ocean the than previous decades.

Answer:

It will be seen in every place close to the sea or beaches also many island will go under.

The projected world population (in billions of people) t years after
MA_775_DIABLO [31]

Answer:

y = 5 e^r * t

Let y be the population in billions and t the value of elapsed years

7 =   5 e^r * t  is the equation being used where  t = 15

7/5 = e^r * t

ln 7/5 = r * t     taking ln of both sides

r = .336 / 15 = .0224

y = 5 e^(.0224 t)    is then our equation

Check  - suppose you want y at 2020

y = 5 e^(.0224 * 20)    would be the equation

y = 5 e^.449 = 7.83  billion - seems to be a reasonable answer
