The ratio of the height of the two buildings is 7 to 5. The first building is 210 feet tall. How tall is the second building?
Factor the polynomial 5x - 15
-
5x - 3(5)
-
x = 5
-
3(x - 5)
-
x = 3
-
5(x - 3)
If 10 is separated into two parts, one of which is y, represent the second part.
-
10 - y
-
10 + y
-
y - 10
-
10 / y
-
10 > y
Find 3 consecutive numbers such that 3 times the first is equal to 8 more than the sum of the other two.
-
12, 13, 14
-
13, 14, 15
-
11, 12, 13
-
9, 10, 11
-
8, 9, 10
If x equals 5, what is the value of
6x + 2x - x?
Add the following:
3x - 2y + 2y + 3z + 2z - 4x - 5y.
-
x - 5y - 5z
-
x + 5y - 5z
-
-x - 5y + 5z
-
x + 5y - z
-
-x - 5y - z
Solve for x:
6x - 10 = 4(x + 3)
-
x = 11
-
x = 13
-
x = 10
-
x = 9
-
x = 12
