Answer:
x = 1.14
Step-by-step explanation:
3(2x - 1) + 7 = 6x - 3 - 2(-4x) [Given Equation]
6x - 3 + 7 = 6x - 3 + 8x [Distributive Property]
6x + 4 = 14x - 3 [Combine like-terms]
-8x + 4 = -3 [Subtraction Property of Equality]
-8x = -7 [Subtraction PoE]
x = 1.14 [Division PoE]
Answer:
2.375 has the same value as 2 and 3/8.
64 = 4³
-216 = (-6)³
.008 = 0.2³ . . . . . . 1000 = 10³, 8 = 2³. This is 8/1000, so the cube of 2/10
1/64 = (1/4)³ . . . . . . the inverse of the first number
4 17/27 = 125/27 = (5/3)³
_____
You can see that it would be helpful to have memorized the cubes of small integers.
Answer:
The volume of a rectangular pyramid is found using the formula: V = (1/3) × L × W × h, where L x W represents the base area of the rectangular pyramid and h represents its total height.
Step-by-step explanation:
z ÷ 3 - 4z + 4(z - 5); z = 15
z ÷ 3 - 4z + 4(z - 5) =
= 15 ÷ 3 - 4(15) + 4(15 - 5)
= 5 - 60 + 4(10)
= -55 + 40
= -15
Answer: -15
