 s=8

Step-by-step explanation:

Let's solve your equation step-by-step.

s(11−s)=24

Step 1: Simplify both sides of the equation.

−s2+11s=24

Step 2: Subtract 24 from both sides.

−s2+11s−24=24−24

−s2+11s−24=0

Step 3: Factor left side of equation.

(−s+3)(s−8)=0

Step 4: Set factors equal to 0.

−s+3=0 or s−8=0

s=8

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
