The length of a rectangle is 11 in. longer than its width. The perimeter of the rectangle is 86 in.
GenaCL600 [577]
P = 2(L + W)
P = 86
L = W + 11

86 = 2(W + 11 + W)
86 = 2(2W + 11)
86 = 4W + 22
86 - 22 = 4W
64 = 4W
64/4 = W
16 = W

L = W + 11
L = 16 + 11
L = 27 <====

Devon exercised the same amount of time each day for 5 days last week. e His exercise included walking and swimming. e Each day
prohojiy [21]
I think that Devon swam at least 35 minutes each day for 5 days because if he exercised 225 minutes and each day he walked for 10 minutes then if you divide 225 by 5 you get 45 so every day he exercised 45 minutes and since he walked for 10 minutes you subtract 10 from 45 which gives you 35 so he swam for 35 minutes.

Sylvia buys a case of water that contains 24 bottles and sells x number of bottles to her co-workers. Sam buys a case of water t
Brrunno [24]

It is given that Sylvia sells x number of bottles and Sam sells three times as many bottles as Sylvia sold to his co-workers.

So, number of bottles Sam sold is 3x.

It is also given that, number of remaining bottle Sylvia and Sam have same.

So,

24 - x = 36 - 3x

3x - x = 36 - 24

2x = 12

x = 6

Therefore, Sylvia sells 6 bottles.

Hence, this is the required solution.
