Based on my calculation i know for sure F
would equal 10
Answer: Box3 has 120 oranges.
Box1 has 150 oranges.
Box has 130 oranges.
Step-by-step explanation:
I will answer this in English.
The question says:
3 boxes have 400 oranges.
The first one has 20 more than the second and 30 more than the third.
So we have 3 equations:
box1 + box2 + box3 = 400
box1 = box2 + 20
box1 = box3 + 30
Now, we can take the variable box1 in the third equation and replace it on the other two.
box3 + 30 + box2 + box3 = 400
box3 + 30 = box2 + 20
Now we can isolate one of the variables in the second equation, let's isolate box2.
box2 = box3 + 30 - 20 = box3 + 10
now we can replace it in the other equation:
box3 + 30 + box2 + box3 = 400
box3 + 30 + box3 + 10 + box3 = 400
3*box3 + 40 = 400
3*box3 = 400 - 40 = 360
box3 = 360/3 = 120.
Box3 has 120 oranges.
Box1 has 120 + 30 = 150 oranges.
Box has 150 - 20 = 130 oranges.
Answer: 2/7

Answer:
B)1/2
Step-by-step explanation:
<u>Step 1: Find the odd numbers in a fair cube</u>
Total numbers in cube: 1,2,3,4,5,6 = 6
Odd numbers in a cube: 1,3,5 = 3
<u>Step 2: Apply the formula of probability</u>
<em>Probability = Number of favourable outcomes/Total number of outcomes</em>
Probability = 3/6
Probability = 1/2
B) 1/2 is the correct answer.
