stiks02 [169]3 years ago
5 0

Hello there!


What is 25% of 400?

\frac{25*400}{100}

= \frac{10,000}{100}

= 100

Thus,

25% of 400 is 100


What is 5% of 20?

Well, we just need to follow the previous steps.

\frac{5*20}{100}

= \frac{100}{100} = 1

Thus,

5% of 20 is 1


I hope this answer helps. Let me know if you have additional questions about the answer. As always, it is my pleasure helping student like you.

trapecia [35]
The answer is 3x^2-19x+1

(-4x+3)-(7x-3x^2-1)
-12x+7x+3x^2+1

Combine like terms:
3x^2+(-12x+-7x)+1
= 3x^2+-19x+1

 Solve the system of inequalities and indicate all the integers which are in the solution set:
elena-s [515]
1.) a>10
2.) a<3.5
How I got it: 1.) Subtract 3 from both sides, leaving -2a<10.
2.) Divide by -2 from both sides, remember to flip the inequality sign when dealing with negatives. This leaves you with a>10.
For number 2.) I divided both sides by 5, leaving a<3.5, though this answer may be wrong.

Graph x&lt;2.
bazaltina [42]

Answer:

A graph showing a range of negative three to two on the x and y axes. A dotted line with arrows at both ends that passes through the x axis at two and runs parallel to the y axis. The graph is shaded to the left of the line.

Step-by-step explanation:

The inequality given is x < 2. This means x is less than two are the values that satisfy the equation.

The equation can be written as x=2 to identify the position where the line will pass. The line is dotted and will pass through x=2 to be parallel with the y-axis.

The second and third answers are not correct because the line should not be solid.

The first answer is not correct because the shaded part should be to the left of the line.

Its for sure not C. because, 49^4 = 5,764,801
