Question

justin was trying to figure out how to write the expression 7 less than 'the double of twenty five. help justin write the expression correctly, and then solve.

Answer 1

The double of 25 is (25+25), or (25x25). 7 less would be (25+25) -7. Figure out what 25 + 25 is, then subtract 7 from your answer.

Answer 2

25 x 2 -7 = 43.

Hi! The “7 less than” would immediately go to the back because it is subtracting from something. The double means to multiply the 25 times two. You wouldn’t need parenthesis because of the rules of PEMDAS. 50-7 = 43.

Hope this helps!
