Write the phrase as an expression. 7 less than a number x

Hi there!

7 less than a number x.

The "Less than" sign would be < in your case since 7 will be less than x.

The answer to your equation would be 7 < x

Hope this helped!~

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
