Solve for z:
-8z + 4 < -4 - 9z
| z < -8 | |
| z < -3 | |
| z < -2\(\frac{1}{4}\) | |
| z < -4 |
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 < sign and the answer on the other.
-8z + 4 < -4 - 9z
-8z < -4 - 9z - 4
-8z + 9z < -4 - 4
z < -8
The dimensions of this cube are height (h) = 5, length (l) = 2, and width (w) = 1. What is the volume?
| 20 | |
| 252 | |
| 10 | |
| 49 |
The volume of a cube is height x length x width:
v = h x l x w
v = 5 x 2 x 1
v = 10
What is 6a9 - 7a9?
| -1a9 | |
| 13 | |
| -a18 | |
| a918 |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
6a9 - 7a9 = -1a9
If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
midpoints |
|
bisects |
|
intersects |
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 trapezoid is a quadrilateral with one set of __________ sides.
equal length |
|
equal angle |
|
parallel |
|
right angle |
A trapezoid is a quadrilateral with one set of parallel sides.
