The sum of three consecutive even integers is 72. Let x represent the first integer, x + 2 represent the second integer, and x + 4represent the third integer.
Which equation can be used to find the first integer?
0 3x + 6 = 72
0 3х + 72 = 2х +6
03x = 2х +6
2x + 64 = 72

Answers

Answer 1

Answer:

3x + 6 = 72

Step-by-step explanation:

x + x + 2 + x + 4 = 72

What is called co-ordinate?

Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ).
There are several coordinate schemes commonly used by mathematicians, scientists, and engineers.

What is co-ordinate with example?

A set of values that show an exact position.
On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down.
Example: the point (12,5) is 12 units along, and 5 units up.

What is the co ordinate formula?

One of the important formula of coordinate geometry is the equation of the straight line which is y = mx + c.
Here m is the slope and c is the y-intercept (tan θ = m, here θ is the angle that the line makes with the positive x-axis).

What is coordinate of a point?

The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane.
Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis.
The coordinates of a given point represent how far along each axis the point is located.

Question 2(Multiple Choice Worth 4 points)(02.01 LC)
Figure EFGHK as shown below is to be transformed to figure E'F'G'H'K' using the rule (x, y) (x+8, y + 5):

Answers

Answer:

H' (4, 8 )

Step-by-step explanation:

the transformation rule (x, y ) → (x + 8, y + 5 )

means add 8 to the original x- coordinate and add 5 to the original y- coordinate, then

H (- 4, 3 ) → H' (- 4 + 8, 3 + 5 ) → H' (4, 8 )

In converting 105 seconds to minutes, what unit (omit the number) would you place in the denominator of your ratio? Use the plural form in your answer. Remember that there are 60 seconds in 1 minute.

Answers

Convert 105 seconds into minutes

60 seconds = 1 minute

105 seconds * 1minute/60 seconds = (105 * 1 minute)/ 60 = 105 min / 60 = 1.75 minutes

The unit that you place in the denominator of your ratio is seconds. This will cancel out the seconds placed in the numerator of 105.
