Answer:
45h=d
Step-by-step explanation:
If d represents the distance in miles, then the equation would be 45h=d because when you multiply 45 by the amount of hours h, then you would get the total distance in miles. For example, Oliver drives 45 miles per hour for 3 hours. When we substitute h, the number of hours, for 3, then we get:
45(3)=d
And all we need to do is to multiply them together to get d, which in this case, it is 135 miles.
The answer for that is 23/16
Dilations stretch or shrink a pre-image. A scale factor greater than 1 will produce an enlargement of the pre-image, and a scale factor less than 1 will produce a reduction of the pre-image. If the scale factor is 1 the pre-image and the image are congruent.
The scale factor between 0 and 1 would result in a dilation that is a reduction.
