Answer:

|8|

Step-by-step explanation:

Let the integer = x

x = - 2x - 24

x + 2x = - 24

3x = - 24

x = - 24/3

x = - 8

Hence, the integer is - 8

The number could be the positive of negative of 8

Hence, it is better expressed as |8|

A satellite is composed of 30 modular units, each of which is equipped with a set of sensors, some of which have been upgraded.

Anit [1.1K]

Answer:

$\frac{1}{7}$

Step-by-step explanation:

The satellite has 30 modular units.

There are equal numbers of non-upgraded sensors in each unit.

Let us assume that on the entire satellite there are x numbers of upgraded sensors.

Then as per the given condition, there are $\frac{x}{5}$ number of non-upgraded sensors in one unit.

Therefore, the number of non-upgraded sensors on the entire satellite is $\frac{30x}{5}$ =6x

Hence, total number of sensors in the satellite is (x+ 6x) =7x

Therefore, the required fraction of the upgraded sensors is $\frac{x}{7x} =\frac{1}{7}$ . (Answer)

I'll name you the BRAINIEST if you can answer this.The scale factor for a model is 18 cm

bezimeni [28]

Answer:

32.625 m

Step-by-step explanation:

You have the proportion ...

18 cm : ___ m = 22.4 cm : 40.6 m

This can be rearranged to ...

___ m/(18 cm) = (40.6 m)/(22.4 cm)

Multiplying by 18 cm gives ...

___ m = (40.6 m)·(18/22.4)

___ m = 32.625 m
