-2(x-3) >-8 What is the answer

Mathematics
1 answer:
Vlad [161]3 years ago
5 0

Answer:

x < 7

Step-by-step explanation:

First apply the -2 onto each term that it is being multiplied onto.

-2x + 6 > - 8

Now subtract six from both sides.

-2x > -14

Now divide by -2.

x < 7

<u>REMEMBER</u>

When doing greater than and less than equations like this, if you divide by a negative you must flip the greater than/less than.

How do you work this out
oksian1 [2.3K]

Answer:

Below.

Step-by-step explanation:

To find the number of students in each grade you multiply the marks by the frequency density. The number of students is given by the area under the  rectangles.

So to find the number of students with grade U (< 160)  it is:

120 * 0.2 + 40*0.5

= 24 + 20

= 44.

The number for Grade E

= (200 - 160) * 0.5

= 40 * 0.5

= 20.

The others can be found in the same way.

boyakko [2]

Answer:

5 meters.

Step-by-step explanation:

Given:

Mr. Dyer is leaning a ladder against the side of his house to repair the roof.

The top of the ladder reaches the roof, which is 3 meters high.

The base of the ladder is 4 meters away from the house, where Mr. Dyer's son is holding it steady.

Question asked:

How long is the ladder?

Solution:

<em>Here we found that a right angle triangle is formed in which base and height is given and we have to find the longest side of the triangle.</em>

Base = 4 meters

Height = 3 meters

Length of the ladder = ?

<u>By Pythagoras theorem: </u>

Square of longest side = Square of base + Square of height

(Longest\  side)^{2} =  4^{2} +3^{2}

(Longest\  side)^{2} =  16+9

(Longest\  side)^{2} =  25

Taking root both side :-        

\sqrt[2]{(Longest\ side)^{2} } =\sqrt[2]{25}    

 Longest\  side =  \sqrt[2]{5\times5} \\  Longest\  side =  5

Thus, length of ladder is 5 meters.
