First you change the number that is not with "p" and it changes with the opposite sign
-0.75p = 0.25 + 2
-0.75p = 2.25
then as -0.75 and p are multiplying, you pass -0.75 as dividing
p = 2.25/-0.75
p = 3
the anwser is
Step-by-step explanation:
the anwser is 5 kg
l = 2w + 4
l * w = 48
We can substitute l with its value:
2w + 4 * w = 48
2w^2 + 4w - 48 = 0
2(w^2 + 2w - 24) = 0
2(w+6)(w-4) = 0
w = {4, -6}
Answer is 3 1/10
6 1/2 - 3 2/5 =
13/2 - 17/5 =
65/10 - 34/10 =
31/10 = 3 1/10
2 2/3 ÷ 5/6 = 3.2 is the answer
