The answer is 7x - 23

You first multiply 5 by what's in the parenthesis and when you do this you get 5x - 20 after that you combine like terms so 5x + 2x is 7x and -20 + (-3) is -23

Leaving you with the answer of 7x - 23

-1=10-1

-1=-1

lHS=RHS

Hence (/,-1) is the solution of y=2x-11

Round to the nearest hundredth 5/8

Solnce55 [7]

Eighths and their multiples are common fractions which I recommend memorizing, but to actually solve this, you use the literal meaning of a fraction and divide 5 by 8. See the long-division below (it was surprisingly difficult to type, so I hope it helps!).

To round 0.625 to the nearest hundredth, we go to the second decimal place, which is 5, so we round up to 0.63.
