Equation Value Say, whether the equation is satisfied. Irfan has 37 marbles. Take m to be the number of Parmit's marbles. He is 4 years older than three times Laxmi's age. Take Laxmi's age to be y years. The highest Score is Take the lowest score to be l. Let the base angle be b in degrees. Remember that the sum of angles of a triangle is degrees. If she adds 19 to it and divides the sum by 5, she will get 8. The highest score is What is the lowest score? What are the base angles of the triangle? Together, their runs fell two short of a double century. How many runs did each one score?

The sum three times n and 7 is 1. Question Set up an equation in the following case: In an isosceles triangle, the vertex angle is twice either base angle.

The value of the expression 10y — 20 depends on the value of y. Verify this by giving five different values to y and finding the value of 10y — 20 for each. In the following we find the value of expression 10y — 20 by taking 5 different values of y. From the above table; We observe that for each value of variable y there corresponds to a unique value of expression 10y — Thus, it is verified that the value of expression 10y — 20 depends on the value of y. Let us try for more values to y. If you multiply a number p by 5; you get
