A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
Solve for b:
4b + 3 = \( \frac{b}{-3} \)
| \(\frac{9}{19}\) | |
| -\(\frac{6}{7}\) | |
| -\(\frac{9}{13}\) | |
| -1\(\frac{10}{17}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
4b + 3 = \( \frac{b}{-3} \)
-3 x (4b + 3) = b
(-3 x 4b) + (-3 x 3) = b
-12b - 9 = b
-12b - 9 - b = 0
-12b - b = 9
-13b = 9
b = \( \frac{9}{-13} \)
b = -\(\frac{9}{13}\)
If the length of AB equals the length of BD, point B __________ this line segment.
midpoints |
|
trisects |
|
intersects |
|
bisects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
A coordinate grid is composed of which of the following?
x-axis |
|
all of these |
|
y-axis |
|
origin |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
Which of the following is not a part of PEMDAS, the acronym for math order of operations?
addition |
|
exponents |
|
division |
|
pairs |
When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
