Hello. All of the answers in the WyzAnt Answers section are free :) Let's look at your problem:
(1249 / x) / 6.849 = 39.08
(1249 / x) / 6.849 * 6.849 = 39.08 * 6.849
1249 / x * x = 267.65892 * x
267.65892x / 267.65892 = 1249 / 267.65892 (I switched the sides of the equation...
How's it going? There're a couple of different ways to look at this problem, but here's the way that makes the most sense to me:
Each of 6 masons works 13 hours to build 1 wall.
6M * 13H = 1W
I think it's simplest to look at this as:
78MH = 1W
1350x + 750y = 14850
1350x + 750y - 750y = 14850 - 750y
1350x / 1350 = (14850 - 750y) / 1350
x = (14850 / 1350) - (750y / 1350)
From here, we simplify. It turns out that 14850, 1350, and 750 are all multiples of 150, so we will divide everything by 150 to simplify...
Hello there :) Let's see:
(2x + 10) + 8 = 2x + 18
The Commutative Property deals with the arrangement of the terms. Think of the word "commute," which reminds us of movement. The Commutative Property would look like this:
(2x + 10) + 8 = 8 +...
Hello :) Let's take a look at this problem.
3zx^2 + 2z^3 - 3yz = 0
Let's start by moving the 3yz over:
3zx^2 + 2z^3 = 3yz
Implicit differentiation is really just differentiating without making an explicit statement. In other words, we will leave this equation "as...
How's it goin? Let's take a look at your problem:
The perimeter of a rectangle is 38 ft. The length is 5 ft. longer than the width.
Ah, a nice tasty word problem. Word problems truly are tasty, but it is an acquired taste, for sure.
Well, we know that a rectangle is a...
