Answer:

x = 27

Step-by-step explanation:

x = y x 3.

5 = y, x = 15.

5 x 3 = 15.

y = 9.

9 x 3 = 27.

Andreyy89

Answer:

.1 (or 1/10)

Step-by-step explanation:

3 * 10^9 = 3 * 10^8/x

<em>Use PEMDAS to interpret</em>

3* 10^9  = 3 * (10^8)/x

<em>Divide both sides by 3</em>

10^9 = (10^8)/x

<em>Divide both sides by 10^8</em>

10 = 1/x

<em>Find the reciprocal of both sides</em>

1/10 = x

On a coordinate plane, a dashed straight line has a negative slope and goes through (0, 3) and (2, negative 1). Everything to th
Nimfa-mama [501]

Answer:

The answer to your question is    y < -2x + 3

Step-by-step explanation:

See the graph below

Process

1.- Find the slope

   m = \frac{y2 - y1}{x2 - x1}

Substitution

   m = \frac{-1 - 3}{2 - 0}

   m = \frac{-4}{2}

   m = -2

2.- Find the equation of the line

   y - y1 = m(x - x1)

Substitution

  y - 3 = -2(x - 0)

Simplify and solve for y

  y - 3 = -2x

  y = -2x + 3

3.- Write the inequality

As the left area of the plane is shaded the inequality must be

 y < -2x + 3

A trapezoid has height 20 inches. Its bases have sum 30 inches, and one base is 6 inches longer than the other. What is the area
Free_Kalibri [48]

Answer:

300 square inches

Step-by-step explanation:

Area of a Trapezoid = 1/2 (b1 + b2 ) × h

h = height 20 inches

b1 = First base = ?

b2 = Second base = ?

From the Question

b1 + b2 = 30 Inches

Hence,

Area of the Trapezoid = 1/2 (30) × 20

= 1/2 × 30 inches × 20 inches

= 300 square inches

The Area of the Trapezoid = 300 Square inches
