Answers

Answer:

9

Step-by-step explanation:

First off you need to find the interval that four falls in.  

Four is not less than three so you can rule out the first one, four is not greater than 10 so you can rule out the last one.  But four is greater than three and less than ten, so it falls in the second interval.

So, now you can substitute four in for x for the second equation

solve the inequality 3x+3>48

Answers

Explanation:Given the Inequality.

[tex]3x + 3 > 48[/tex]

Solving the Inequality is similar to solving the equation. We simply make x-term as the subject since we are solving for x.

[tex]3x > 48 - 3 \\ 3x > 45 \\ x > \frac{45}{3} \Longrightarrow x > \frac{ \cancel{45}}{ \cancel{3}} \Longrightarrow x > \frac{15}{1} \\ x > 15[/tex]

Answer Check

Because x must be greater than 15. We will substitute x = 16 in the Inequality.

[tex]3(16) + 3 > 48 \\ 48 + 3 > 48 \\ 51 > 48 \: \: \checkmark[/tex]

The Inequality is true when x > 15.

Answer

[tex] \large \boxed{x > 15}[/tex]

if 0.4 < x > 45%, which of the following could be the value of x?​

Answers

Answer:

0.41, 0.42, 0.43, 0.44

Step-by-step explanation:

Convert the percent to a decimal:

0.4 < x > 0.45

Now, the variable x has to be any number between 0.4 and 0.45, which include:

0.41, 0.42, 0.43, 0.44

Answer:

5/10

Step-by-step explanation:

So you can split this into two inequalities, x > 0.4 and x > 45%. First you can change the second one to decimal form, so x > 0.45. Because 0.45 is already greater than 0.4, you can just ignore the second inequality. (If x is greater than 0.45 it will automatically be greater than 0.4 so it doesn't matter).

From the 4 options you gave, 5/10, or 0.5, is the only one that is greater than 0.45.

Erin and her friends are taking a road trip. She has agreed to drive between hours 3 and 6 of the trip. If h represents the hours of the trip Erin will be driving, then h ≥ 3 and h≤ 6 represents her portion of the driving. While she is driving, her distance and time are modeled by the inequality d < 70h. What are the possible hours and distances Erin could be driving?

When graphing this scenario, let h be the horizontal variable and d be the vertical variable.

For the inequality h ≥ 3, the graph should be shaded
the boundary line.

For the inequality h ≤ 6, the graph should be shaded

Theorem:

The measure of an exterior angle of triangle equals the sum of the measures of its two remote interior angles.

The angle measuring 12x + 14 is an exterior angle of the triangle.

The angles measuring 76 deg and 1 + 5x are its remote interior angles.

12x + 14 = 1 + 5x + 76

12x + 14 = 5x + 77

7x = 63
