There are 128 kg of oranges in two boxes, how many kg are in each one or in one of them there are 3 times more oranges than the other

first box:32kg

second box:96kg

Step-by-step explanation:

Using principle of linear equation, we can make the two boxes be represented by the variables "x" & "y"

The total amount of kg within the two boxes:128kg so becomes

the x plus y equal to 128 but one is 3 times more than the other so y becomes equals to 3x so equation is

x plus 3x equals to 128

4x equals 128,dividing both sides by 4

x equals to  32 so 1st box is 32kg

y equals 3x so 3(32) equals to 96, making 2nd box becoming 96kg

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8
