This should help you here are the steps of your problem :)

2*(1/2)*r+2*r+1 = 9*(1/10) // - 9*(1/10)

2*(1/2)*r+2*r-(9*(1/10))+1 = 0

2*(1/2)*r+2*r-9/10+1 = 0

3*r+1/10 = 0 // - 1/10

3*r = -1/10 // : 3

r = -1/10/3

r = -1/30

So your answer would be 1/30

Sarah can take no more than 22 pounds and I like the trap her suitcase weighs 112 ounces how many more pounds can she park witho

Leya [2.2K]

Answer:

15 pounds

Step-by-step explanation:

there are 16 ounces in one pound

so...

first find the limit in ounces

$22 = \frac{x}{16}$

because there are 16 ounces in every one pound you need to multiply 22 by 16

which is 352

now subtract what you already used

$352 - 112$

which is 240

now convert to pounds

$x = \frac{240}{16}$

which is 15

so 15 more pounds
