In a quadrilateral mnop the length of side mn is (4x − 7) units and the length of side on is (7 − 3x) units. what value of x will make it a rhombus? 14 2 7 12

In a rhombus, all sides are equal.

So for the quadrilateral MNOP to be a rhombus, the given sides have to be equal. THat is

Adding 3x to both sides and addinf 7 to both sides

Now we need to get rid of 7 and for that we do division, that is

Correct option is the second option .

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

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
