Solve the following equations using algebraic operations ( 4x-1=2x+11)
liq [111]

Answer:

x = 6

Step-by-step explanation:

4x-1=2x+11

Subtract 2x from each side

4x-2x-1=2x-2x+11

2x-1 =11

Add 1 to each side

2x-1+1 = 11+1

2x = 12

Divide by 2

2x/2 = 12/2

x = 6

What is equivalent to -1/4y -2 1/4y + 1/2 (4-2y)
yan [13]

Answer:

14y - 8 = 0

Step-by-step explanation:

-  \frac{1}{4} y - 2 \frac{1}{4} y +  \frac{1}{2} (4 - 2y) = 0 \\

-  \frac{1}{4} y -  \frac{9}{4} y + 2 - y = 0

( -  \frac{1}{4} y -  \frac{9}{4} y + 2 - y = 0)4

- y - 9y + 8 - 4y = 0

- y - 9y - 4y + 8 = 0

- 14y + 8 = 0

14y - 8 = 0

Two ropes, AD and BD, are tied to a peg on the ground at point D. The other ends of the ropes are tied to points A and B on a fl
Kazeer [188]

Answer: 10 ft

Explanation

As two right triangles (a triangle with a 90º angle) are formed, to know the distance between AB we have to calculate BC, AC and subtract.

0. Calculating BC

We have a 30º angle and an adjacent side 5√3ft (as the hypotenuse is the side opposite to the 90º angle). Thus, using the tangent function where:

\tan\theta=\frac{opposite}{adjacent}

we can find the opposite side, which is BC. Replacing the values and simplifying we get:

\tan(30\degree)=\frac{BC}{5\sqrt{3}}BC=5\sqrt{3}\tan(30\degree)BC=5ft

Thus, the segment BC measures 5ft.

<em>2. Calculating segment AC</em>.

In this case, our hypotenuse changes. However, we are still looking for the opposite side. Using the tangent function as before we get:

AC=5\sqrt{3}\tan(60\degree)AC=15

<em>3. Calculating the distance between A and B</em>

AC-BC=15-5=10ft
