What is the inequality to 2w+5>45

Mathematics

Tanzania [10]3 years ago
4 0

Answer:

  w > 20

Step-by-step explanation:

Perhaps you want the solution to the inequality 2w+5>45.

Subtract 5:

  2w > 40

Divide by 2:

  w > 20 . . . . this is the solution

_____

<em>Comment on solving inequalities</em>

An inequality is solved in virtually the same way that an equation is solved: <em>undo what is done to the variable</em>. The only difference is that when you perform an operation that reverses the ordering, you need to reverse the ordering symbol.

Multiplying or dividing by a negative number will reverse the ordering. Consider, for example, ...

  2 > 1

Multiplying both sides by -1, we get ...

  -2 < -1 . . . . . the > sign needs to be reversed to a < sign to keep the inequality true

Write the equation of the line that passes
grandymaker [24]

Answer:

y=2x+2

Step-by-step explanation:

The equation will be y=2x+b.  Note the slope is 2, since this line is parallel to y=2x+14.

Substitute (2,6) in it and we get 6=2(2)+b

6=4+b

b=2

So y=2x+2

I need the answer for 4. and 5.
Gwar [14]

Exercise 4

A grow from 13.1 millions to 14.4 millions means to grow

14.4-13.1 = 1.3

millions. So, the question is: which percentage of 13.1 is 1.3? Well, we have to find a number x such that

\dfrac{x}{100}\cdot 13.3 = 1.3

Solving for x, you have

x = \dfrac{1.3 \cdot 100}{13.3} \approx 9.92

Exercise 5

27% is a bit more than 25%, which is a quarter. So, we expect to find a pie chart with one slice occupying roughly one quarter of the pie. The example that best suits this requirement is B (A is almost half, and C is less than one quarter).
