Gabby bought 5.15 kg of apples and 1.6 kg of oranges how much fruit did she buy in all

6.75kg of fruit

Step-by-step explanation:

5 + 1 = 6

.15 + .6 = .75

6 + .75 = 6.75

6.75

Step-by-step explanation:

Add 5.15 and 1.60

5.15

1.60

6.75

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
