Aseem and Stana are building model cars. Stana's car is 5 less than 2 times the length of Aseem's car. The sum of the lengths of
both cars is 20 inches. Write an equation to determine the lengths of Aseem's and Stana's cars. 2x − 5 + x = 20
5 − 2x + x = 20
2x − 5 = 20
5 − 2x = 20
6 x 89 is 534 6 x (90 - 1) is 534. BUT you have to subtract 90 from 1 and that's 89. So then you multiply 6 by 89. 6 x 90 is 540 and 6 x 1 is 6. you take 540 subtract 6 and that's 534. 540 - 6 is 534.
