Step-by-step explanation:

<u>Step 1: Define</u>

7a + 42 + 8 < -10 + 9a - 64a

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Combine like terms (a):                                                                                    7a + 42 + 8 < -10 - 55a
  2. Combine like terms:                                                                                         7a + 50 < -10 - 55a
  3. [Addition Property of Equality] Add 55a on both sides:                                62a + 50 < -10
  4. [Subtraction Property of Equality] Subtract 50 on both sides:                      62a < -60
  5. [Division Property of Equality] Divide 62 on both sides:                               a < -30/31

Here we see any number <em>a</em> less than -30/31 would work as a solution to the inequality.

A 10 ft. tent pole has a support rope that extends from the top of the pole to the ground. The rope and the ground form a 30 deg
GrogVix [38]
So you have a pole that is 10 feet tall that has a rope that goes from the top to the ground, the rope being 30 degrees to the ground... You can draw a right triangle using these dimensions. Now that you have a triangle, you look at where your 30degree angle is related to the side whose length you know and the side whose length you wish to find. The side you know is opposite from the 30 degrees while the side you want to find is the hypotenuse, for it goes down at an angle. You will use the opposite and hypotenuse sides, so, according to SOH CAH TOA, you will be using sin.
\frac{opposite}{hypotenuse}=sin\theta,\theta=30,opposite=10,hypotenuse=?
plug in those values and solve for your hypotenuse.
The easiest way to do this is if you knew the identities for special right triangles like the 30 60 90 triangles or the 45 45 90 triangles, but I showed you how to solve for your sides even if they're not special

I need to simplify this complex fraction
vovangra [49]

I see two ways to do it.

First, you have to understand that when you see a 'complex fraction' like this, the top number is a numerator, and the two bottom numbers are both denominators.

Way-1:

Take the top fraction . . . 2/2 .  That's equal to 1 . So the whole thing is <em>1/3</em>.

Way-2:

Multiply the bottom two denominators.  Then the whole thing is 2/(2·3) .  That's the same thing as  2/6 .  Simplify that, and you have <em>1/3</em> .

Courtney and Chelsea are leading a family hike on Saturday. The number of snacks Chelsea is bringing can be represented by 2x. C
myrzilka [38]

Answer:

Courtney is bringing 8 snacks

Step-by-step explanation:

Chelsea's snacks are represented as 2x.

2x means <u>2 · (a number)</u>

If Chelsea brought <u>16 snacks</u> and the <u>amount of snacks represented by 2x</u>, we have to figure out <u>what times 2 equals 16.</u>

In order to find out, we have to <u>divide</u>.

16 ÷ 8 = 2

This means 2 · 8 = 16

Since the amount of snacks Courtney brings is represented as <u>"x"</u>, she would have brought 8 snacks.

Hope this helped! :)
