Answer:
the solution is given by s=9 because it makes the value of 3s+12 equal to 21
Step-by-step explanation:
Write an expression for the perimeter of each. Then set them equal and solve for w.
2(w+3) + 2w = 2(2w-5) + 2(w+1)
Is that enough info?
Answer:
1.5 sweaters or 1 and half of a sweater
Step-by-step explanation:
you would multiply 6 by 3/12 and get 1 and a half
-6x -17 ≥ 8x + 25
Subtract 8x from each side:
-14x -17 ≥ 25
Add 17 to each side:
-14x ≥ 42
Divide each side by 14 :
-x ≥ 3
Change the signs. (Multiply each side by -1.)
That's when you have to flip the inequality symbol.
x ≤ -3
