What is 9c+90<-27?????​

Mathematics
1 answer:
antoniya [11.8K]3 years ago
5 0
<h3>Answer:  c < -13</h3>

========================================

Work Shown:

9c + 90 < -27

9c + 90 - 90 < -27 - 90 .... see note 1

9c < -117

9c/9 < -117/9 ... see note 2

c < -13

-----------

note 1: I'm subtracting 90 from both sides to undo the "plus 90" that is happening on the left side

note 2: I divided both sides by 9 to undo the multiplication. The expression 9c is the same as 9*c or "9 times c". The inequality sign will <u>not</u> flip as we are dividing both sides by a positive number.

A light bulb distributor was given a study from an LED bulb manufacturer showing that LED light bulbs are better for the environment than traditionalbulbs. Is there an incentive for this study to be biased? Why or why not?

<span>Yes, because the LED bulb manufacturer may benefit from the survey results.

If the light bulb distributor will decide get more stock of LED bulb due to the study given by the LED company, then, the LED company will benefit from it.

Which expressions can be used to compute the approximate area of triangle XYZ? Check all that apply.
lesantik [10]

Given:

In the given ΔXYZ,

Base = 22

Height = 23.1

Also,

Base = 31.9

Height = 15.9

To find the area of the given ΔXYZ.

Formula

The area of a triangle is

A = \frac{1}{2} bh

where, b be the base and

h be the height.

Now,

Taking, b = 22 and h = 23.1 we get,

A = \frac{1}{2} (22)(23.1) sq unit

Again,

Taking,

b = 31.9 and h = 15.9 we get,

A = \frac{1}{2} (31.9)(15.9) sq unit

Therefore,

We can find the approximate area of the triangle by following two expression

a) \frac{1}{2} (22)(23.1) and

b) \frac{1}{2} (31.9)(15.9)
