Answer:

x=49/34

Step-by-step explanation:

1.) Multiply both sides by 4

(4) 2x+5/4 = 9x-11 (4)

2x+5 = 36x-44

2.) Subtract 2x from both sides

2x+5 = 36x-44

<u>     -2           -2  </u>

5 = 34x-44

3.) Add 44 to both sides

5 = 34x-44

<u>+44      +44 </u>

<u>49=34x</u>

4.) Divide by 34

49/34 = 34x/34

x=49/34

Step-by-step explanation:

\frac{2x + 5}{4}  = 9x - 11

2x + 5 = 4(9x - 11)

2x + 5 = 36x - 44

36x - 44 = 2x + 5

36x - 2x = 5 + 44

34x = 49

x = 49/34

Estimate the perimeter and area of the figure to the nearest whole number. Please help!!
solniwko [45]

Answer:

29 ; 37

Step-by-step explanation:

The figure is composed by a square, a rectangle, and a right triangle

The perimeter of the square is 6 units

The perimeter of the rectangle is 10 units

The triangle is composed by a side of 6 units and a side of 5 units

The third side can be find with the Pythagorean theorem

\sqrt{6^2 + 5^2} = \sqrt{36 + 25} = \sqrt{61} = 7,81025

The total perimeter is

6 + 10 + 5 + 7,81025 = 28,81025 = 29

Area of the square = 2^2 = 4 square units

Area of the rectangle = 6 x 3 = 18 square units

Area of the triangle =  (5 x 6)/2 = 15 square units

Total area = 4 + 18 + 15 = 37 square units

Find the equation of a line that has a slope of 1/2 and passes through the origin.
omeli [17]

Step-by-step explanation:

The equation of a line with slope m and y-intercept b is y = m x + b.  

This line goes through the point ( 0 ,0 ), so the y-intercept is zero.

We are given the slope as − 2 / 3.

The equation of the line is y= – 2 / 3 x + 0 = – 2 / 3 x

y = – 2 / 3 x
