Solve for y:
-8y - 6 > 7 - 2y
| y > -1\(\frac{1}{5}\) | |
| y > -2\(\frac{1}{6}\) | |
| y > \(\frac{4}{5}\) | |
| y > -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.
-8y - 6 > 7 - 2y
-8y > 7 - 2y + 6
-8y + 2y > 7 + 6
-6y > 13
y > \( \frac{13}{-6} \)
y > -2\(\frac{1}{6}\)
If a = c = 4, b = d = 2, what is the area of this rectangle?
| 6 | |
| 18 | |
| 8 | |
| 5 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 4 x 2
a = 8
The dimensions of this trapezoid are a = 4, b = 9, c = 7, d = 6, and h = 3. What is the area?
| 12 | |
| 13\(\frac{1}{2}\) | |
| 22\(\frac{1}{2}\) | |
| 9 |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(9 + 6)(3)
a = ½(15)(3)
a = ½(45) = \( \frac{45}{2} \)
a = 22\(\frac{1}{2}\)
Solve for a:
-6a - 7 = -9 + a
| \(\frac{2}{9}\) | |
| -\(\frac{3}{4}\) | |
| -2\(\frac{2}{3}\) | |
| \(\frac{2}{7}\) |
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.
-6a - 7 = -9 + a
-6a = -9 + a + 7
-6a - a = -9 + 7
-7a = -2
a = \( \frac{-2}{-7} \)
a = \(\frac{2}{7}\)
