gladu [14]

Answer:

No Jeremy can not find the cost of the sneakers by adding the percents, you have to the math one sale discount at a time.

The answer is $45.90.

Step-by-step explanation:

You have to multiply $60 by 15%, getting $9. Subtract 9 from 60 and get the first discount price: $51. Then you will multiply 51 by `10% and get 5.1, subtract 5.1 from 51 and get your final sale price $45.90. If you added the percents together you would get an incorrect value of $45. Close but not the correct answer.

The side of the parallelogram in the figure above are given in cm.

GrogVix [38]

solution

or, 2 x + y = 5 y - 8 being opposite side of

parallelogram

or , 2x =5 y - y - 8

or, 2x = 4 y - 8

or, x = 4y - 8/2

or,. x = 2y- 4

therefore, 2x + y is equal to 5 y - 8 Being the opposite side of a parallelogram

now,

3y + 2 x is equal to 4x - 3 being opposite side of a parallelogram

or, 3y + 2 x-4x = -3

or,. 3y -2x = -3
