please solve all the questions.​

Answer 1

Answer:

a) y-15

b) Refer to the explanation given below

c) 25 %

d) 12.8 cm

e) Like Terms = -2ab and 3ba

Step-by-step explanation:

a) Solve: y-3x5:-

   --> y-15

--------------------------------------------------------------------------------------------------------------

b) Write a statement to represent a variable.

--> A statement to represent a variable can be by marking it or by making equations like 2x = 4, 3y + 2 = 11, etc.

--------------------------------------------------------------------------------------------------------------  c) What percent is 13 weeks of one year?

--> Given, No. of weeks in a year = 52 weeks

Therefore, Required % = 13/52 x 100

                                      = 25 %

--------------------------------------------------------------------------------------------------------------d) The radius of a circle is 6.4 cm Find its diameter.

--> Given, radius = 6.4 cm

Therefore, Diameter = 2r

                                  = 2 x 6.4

                                  = 12.8 cm

--------------------------------------------------------------------------------------------------------------e) Identify the like terms:

-2ab, 5a, 3ba, bac

--> Like Terms = -2ab and 3ba

--------------------------------------------------------------------------------------------------------------

Hope this answer helps you!!
