Answer:

x > $\frac{1}{6}$

Step-by-step explanation:

Given

- 2 (8x - 4) < 2x + 5 ← distribute left side

- 16x + 8 < 2x + 5 ( subtract 2x from both sides )

- 18x + 8 < 5 ( subtract 8 from both sides )

- 18x < - 3

Divide both sides by - 18, reversing the symbol as a result of dividing by a negative quantity.

x > $\frac{-3}{-18}$ , that is

x > $\frac{1}{6}$

Answer: C is closest to the correct answer

<u>Step-by-step explanation:</u>

Convert the inches into feet (12 inches equal 1 foot). Then convert the mixed fractions into improper fractions and multiply.

$11\ ft\ 2\ in=11\dfrac{2}{12}ft\qquad\longrightarrow \qquad11\dfrac{1}{6}ft\qquad =\qquad \dfrac{67}{6}\ ft\\\\\\9\ ft\ 10\ in= 9\dfrac{10}{12}ft\qquad\longrightarrow \qquad9\dfrac{5}{6}ft\qquad =\qquad \dfrac{59}{6}\ ft\\\\\\\dfrac{67}{6}\ ft\times \dfrac{59}{6}\ ft\times \dfrac{\$2.50}{ft^2}=\dfrac{\$9,882.50}{36}\qquad \longrightarrow \qquad \large\boxed{\$274.51}$

Whats the x value of the solution to this system of equations<br> x=2y-4<br> 7x+5y=-66

Likurg_2 [28]

Answer:

x=2y−47x

Step 1: Add 47x to both sides.

x+47x=−47x+2y+47x

48x=2y

Step 2: Divide both sides by 48.

48x

Hi can you please help me

Licemer1 [7]

For this you need to know your angles in parallel lines.
3y will equal 87 as they are opposite angles and opposite angles are equal.
So y = 87/3
We can use the knowledge that angles in a straight line (in parallel line diagrams) will add up to 180. Therefore we do 180-87= 93. Now we know 3x=93 because just like the first example they are opposite angles. Now we know x=93/3.
(I didn’t have a calculator on me so you’ll have to work out the final result. Also I recommend looking into angles in parallel lines. I tried my best to explain so I hope you understand the jist of what I was trying to say.)

The ratio of two side lengths for the triangle is given. What is the value of “q” AB:BC is 3:4

Vera_Pavlovna [14]

Answer:

$q=8.5$

Step-by-step explanation:

The ratio of the side lengths (AB) and (BC) is given. One is also given an expression for the side lengths of each of these sides. Set up a proportion to describe this scenario, then solve using cross products;

$\frac{AB}{BC}=\frac{3}{4}$
