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.
<h3>
Answer: 9/50</h3>
Explanation:
Any percentage converts to that number over 100.
So 18% would convert to 18/100
We then reduce the fraction by dividing each part by the GCF 2
18/2 = 9
100/2 = 50
The fraction 18/100 fully reduces to 9/50
Answer:
x =8
Step-by-step explanation:
-5(x-3)= -25
we apply distributive property
-5*x +5*3 =-25
-5x +15= -25
-5x = -25-15
-5x = -40
x = 40/5
x =8
<u>We are given:</u>
Afsheen can read 39 pages in 30 minutes
<u>Time taken by Afsheen to read 1287 pages:</u>
Time taken to read 1 page:
Time taken to read 1 page = time taken to read 39 pages / 39
Time taken to read 1 page = 30 minutes / 39
Time taken to read 1 page = 0.77 minutes
Time taken to read 1287 pages:
Time taken to read 1287 pages = Time taken to read 1 page * 1287
Time taken to read 1287 pages = 0.77 * 1287
Time taken to read 1287 pages = 991 minutes OR 16.52 hours <em>(Approx)</em>
