Which expressions are equivalent to 10a-25+5b - - - answer now and i will put u give u crown

Answer with explanation:

Two or more expressions are said to be equivalent expression, if we express that expression in any other way,and by substituting the value of variables, we get the same result as in the original.

Original expression = 10 a -2 5 + 5 b

Equivalent Expression = 5 × 2 a - 5 × 5 + 5 × b

                                 = 5× [2 a - 5 + b]

Addition of number follow associative law,that is,→ a +(b+c)=(a+b)+c=(a+c)+b

So,Equivalent Expression to,10 a -2 5 + 5 b are

→ 5× [2 a - 5 + b]

or,→ 5 × [ 2 a + b -5 ]

or,→ 5 × [-5 +b + 2 a]

or,→ 5 × [ b - 5 + 2 a]

or,→ 5× [2 a - 5 ] + 5 b

or, → 5× [b-5]+10 a

or, → 5× [2 a + b]- 2 5

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
