Answer:

\Large\boxed{140}

Step-by-step explanation:

\sf Let \ x \ be \ the \ number.

\sf x \ increased \ by \ 15\% \ is \ 161.

x \times (1+15\%)=161

x \times (1+0.15)=161

x \times (1.15)=161

\displaystyle \frac{x \times (1.15)}{1.15}=\frac{161}{1.15}

x=140

Answer:

100%+15% = 115%

proportionally:

x - 100%

161 - 115%

x = (161 * 100%) / 115% = 140

Make x the subject of formular y=5√x+3-4
pochemuha

Answer:

x={(y+1) / 5}²

Step-by-step explanation:

y = 5√x +3 -4

⇒y = 5√x -1

add 1 on both sides

⇒ y + 1 = 5√x

divide both sides by 5

⇒(y+1) / 5   = (5√x) /5

⇒(y+1) / 5   = √x

now, square both sides

⇒{(y+1) / 5}²  = (√x)²

∴{(y+1) / 5}² = x

Arte-miy333 [17]

Answer:

You are now 38 m below base camp.

Step-by-step explanation:

Consider the provided information.

You start hiking at an elevation that is 80 meters below base camp.

Now your initial location is 80 m below base camp, that can be represents as: -80

Now you increase your elevation by 42.

So you go up by 42.

In other words, you get the equation -80+42 = -38.

Since a negative value is below the base camp, this means that you are now 38 m below base camp.
