Question

Write the following phrases using symbols: (a) 25 decreased 4 times a (b) Thrice the number x increased by y​

Answer 1

Answer:

Step-by-step explanation:

Not every problem can be directly translated like this one, but I will line everything up to see how it goes.

 

Let 'x' be the number for which we are looking.

 

(Twice a number) (decreased by) (8) (is equal to) (the number) (increased by) (10)

        2x                       -              8          =                 x                   +            10.

 

So, we have:

2x - 8 = x +10

--> x = 18, by subtracting 'x' from both sides, and adding 8 to both sides

Answer 2

Answer:

thrice number a increased by b =3(a+b)
