Answer:

C. 98

Step-by-step explanation:

The sum of angles interior to a triangle is 180°, so you have ...

x + 38° + 44° = 180° . . . the sum of the angles (this is your equation)

x + 82° = 180° . . . . . . . . collect terms

x = 180° -82° . . . . . . . . . subtract 82° from both sides of the equation

x = 98° . . . . . . . . . . . . . . do the arithmetic

<em>Comment on the equation</em>

The relations you learn about in math and geometry can all be translated to equations. When you learn "something" <em>is</em> "something else", anytime you have "something", you can always write the equation ...

something = (something else)

When you find out "the sum of angles" is "180 degrees", that means you can write the equation ...

(sum of angles) = 180°

Of course, you find a sum by adding things up. In this case, you're adding up the values of the angles: x, 38°, 44°. The next step is to use the rules of algebra to solve the equation for x.

Answer:

450 minutes

Step-by-step explanation:

15 + 0.1x = 60

15 - 15 + 0.1x = 60 - 15

0.1x = 45

$\frac{0.1x}{0.1} = \frac{45}{0.1}$

x = 450

Eight less than the product of a number n and<br> is no more than 94.

vladimir2022 [97]

First, let's call "a number": n

Then. "eight less than a number" can be written as: n-8

This expression "is no more than 14" can be written as: n−8≤14

Solved and graph each inequality X+7>11

Nina [5.8K]

Answer:

$x>4$

Step-by-step explanation:

Given inequality:

$x+7>11$

We need to solve the given inequality for solutions of $x$ .

In order to solve for the inequality, we will isolate $x$ in one side of the in-equation.

We have,

$x+7>11$

Subtracting both sides by 7.

$x+7-7>11-7$

$x>4$

Thus, the solution of the given inequality is all real numbers greater than 4.

The solution in interval form can be written as (4,∞).

The graph for the inequality is shown below.
