9more than two-sevenths a number is 45. what is the number?
also, show an explanation.

x=126

Step-by-step explanation:

let 'x' represent the unknown number

(2/7)x + 9 = 45

Subtract 9 from both sides

2/7x=36

Because the fraction is being multiplied by 'x' we can multiply both sides by its reciprocal (because a fraction multiplied by its reciprocal is 1 which would 'eliminate' it from the left side therefore isolating 'x').

x=126

Hello. This question is incomplete. the complete question is:

Does the construction demonstrate how to copy an angle correctly using technology? (The construction shows angles CAB and IDE. There is a circle created from point A that intersects with ray AC, creating point F, and ray AB, creating point G. A circle congruent to circle A was created at point D. Circle D intersects with ray DE, creating point H. Another circle was created on point H that has a radius that is congruent to the distance between points A and F. Circle H intersects with circle D, creating point I. A ray was created through points D and I.)

Yes; the distance between points A and F was used to create circle H. Yes; the distance between points F and G was used to create circle H. No; the distance between points A and F was used to create circle H. No; the distance between points F and G was used to create circle H.

No; the distance between points A and F was used to create circle H.

Step-by-step explanation:

The construction does not demonstrate how to copy an angle correctly using technology. The distance between points A and F was used to create circle H, in addition to having no information on the devices used for this, which means that the construction used conventional methods to copy an angle, with technology already known and traditional in the field.
