When 31 times a number is increased by 40, the answer is the same as when 200 is decreased by the number. Find the number.
natulia [17]

Answer:

The Answer is: 5.

Step-by-step explanation:

Let n = number.

The number times 31 plus 40 is equal to 200 minus the number:

31n + 40 = 200 - n

32n = 200 - 40

32n = 160

n = 5

Proof:

31(5) + 40 = 200 - 5

155 + 40 = 195

195 = 195

Hope this helps! Have an Awesome Day!! :-)

The orbit of the planet Venus is nearly circular. An astronomer develops a model for the orbit in which the sun has coordinates
klio [65]
Since the Venus orbits round the sun, the sun is the center of the circular path of the revolution of the planet, Venus.

Thus, the distance of the planet, Venus fron the sun is given by the distance between the points (0, 0) and (41, 53).

Recall that the distance between two points (x_1, y_1) and (x_2, y_2) is given by d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Thus, the distance between the points (0, 0) and (41, 53) is given by:

d= \sqrt{(41-0)^2+(53-0)^2}  \\  \\ = \sqrt{41^2+53^2} = \sqrt{1,681+2,809}  \\  \\ = \sqrt{4,490} =67 \ units

Given that each unit of the plane represents 1 million miles, therefore, the distance from the sun to the Venus is 67 million miles.

If M is the midpoint of XY, find the coordinates of X if M(-3,-1) and Y(-8,6).
NeTakaya

Answer:

(2, -8)

Step-by-step explanation:

The coordinates of M are the average of the coordinates of X and Y.

-3 = (x + -8) / 2

-1 = (y + 6) / 2

Solving:

x = 2

y = -8
