Answer:

y = 14

Step-by-step explanation:

In an isosceles trapezoid, the legs are equal.

      AB = CD

7y – 4 = 8 y – 18     Add 18 to each side

7y + 14 = 8y              Subtract 7y from each side

       y = 14

Answer:

y = 14

Step-by-step explanation:

Since this is an isosceles trapezoid, the legs are congruent.  This means the expressions for AB and CD are equal:

7y - 4 = 8y - 18

Add 18 to each side:

7y - 4 + 18 = 8y - 18 + 18

7y + 14 = 8y

Subtract 7y from each side:

7y + 14 - 7y = 8y - 7y

14 = 1y

14 = y

Question 26 please. will give brainliest
shusha [124]

Answer:

To find how tall he was at the end of the school year, you add his height at the beginning of the year and during the school year. First you should just add the inches.

2 1/4 + 7/8

The common denominator is 8.

2 2/8 + 7/8

2 9/8

3 1/8

Put back in the 5 ft.

So, Jerry was 5ft and 3 1/8 inches at the end of the school year.

Hope this helped! :)
