3x< 21 fill in the blank x < ____

1 answer:

7 0

To solve this problem, you need to have x alone on one side of the inequality. To do this, you need to undo the multiplication that is bonding 3 and x together. To undo this, you need to divide both sides by 3.

This results in the inequality x<7.

Your final answer is x<7.

G(x)=3x+2(x+1) evaluate g(7)

lianna [129]

G(x) = 3x + 2(x + 1)

g(7) = 3(7) + 2(7 + 1)

g(7) = 21 + 2(8)

g(7) = 21 + 16

g(7) = 37

What is the y-intercept and slope <br> of the line

bezimeni [28]

Answer:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".

Find the measure of one interior angle for the following regular polygon

kipiarov [429]

Answer:

144 degrees

Step-by-step explanation:

We can use the formula (n-2)(180), where n = number of sides, to find the sum of all the interior angles in the decagon. Since a decagon has 10 sides:

(n-2)(180) = ?

(10-2)(180) = ?

(8)(180) = 1440.

Now, to find one interior angle in the decagon, divide 1440 by the number sides in our polygon (10).

1,440/10 = 144

= <u>144 degrees</u>
