Divide by 7 and you get x - y = 0 so x must equal y for it to equal 0.

ruslelena [56]

Answer: You would have to send 300 text messages

Step-by-step explanation:

1. Turn problem into 20 + 0.10x = 50

2. Subtract 20 from both sides to get 0.10x = 30

3. Divide both sides by 0.10 to get x = 300

Solve:<br> 5y+34 = -2(-7y+1)
Blizzard [7]

Answer:

Slope = 1.200/2.000 = 0.600

 x-intercept = 34/3 = 11.33333

 y-intercept = 34/-5 = -6.80000

Step-by-step explanation:

1.1     Solve   3x-5y-34  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  3x-5y-34  = 0 and calculate its properties

Geometric figure: Straight Line

 Slope = 1.200/2.000 = 0.600

 x-intercept = 34/3 = 11.33333

 y-intercept = 34/-5 = -6.80000

Determine the volume of the three-dimensional<br> figure.
Finger [1]

Answer:

288 cubic inch

Step-by-step explanation:

Top and bottom bases are trapezoid of same dimensions and height is 4 in.

Therefore,

volume   \\ = area \: of \: trapezoid \times height \\  =   \{\frac{1}{2} (16 + 8) \times 6 \}  \times 4 \\  = 24 \times 6 \times 2 \\  = 48 \times 6 \\  = 288 \:  {in}^{3}  \\
