Still being time (2/4)

The scale factor is 1/4.

Step-by-step explanation:

Dilations

Quadrilateral A'B'C'D' is the result of dilation of quadrilateral ABCD by a scale factor.

To find the scale factor, we compare the measures of the side lengths from consecutive vertices of each quadrilateral.

From A to B, there are 4 units. From A' to B' there is one unit. This gives a scale factor of 1/4.

This happens with the rest of the measures.

From B to C there are 4 horizontal and 4 vertical units. From B' to C' there is one unit of each dimension.

This pattern can be confirmed by comparing any pair of vertices of each quadrilateral, thus we can conclude:

The scale factor is 1/4.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
