A(n) __________ is two expressions separated by an equal sign.
formula |
|
problem |
|
equation |
|
expression |
An equation is two expressions separated by an equal sign. The key to solving equations is to 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.
Order the following types of angle from least number of degrees to most number of degrees.
acute, right, obtuse |
|
right, obtuse, acute |
|
right, acute, obtuse |
|
acute, obtuse, right |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
What is the circumference of a circle with a diameter of 8?
| 2π | |
| 8π | |
| 12π | |
| 13π |
The formula for circumference is circle diameter x π:
c = πd
c = 8π
Solve for z:
-4z + 1 = -5 - 3z
| \(\frac{2}{7}\) | |
| -\(\frac{5}{9}\) | |
| \(\frac{5}{9}\) | |
| 6 |
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.
-4z + 1 = -5 - 3z
-4z = -5 - 3z - 1
-4z + 3z = -5 - 1
-z = -6
z = \( \frac{-6}{-1} \)
z = 6
