34523
Step-by-step explanation:
345-23=po
Answer:
75.3
Step-by-step explanation:
Here we will use algebra to find three consecutive integers whose sum is 228. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 228. Therefore, you can write the equation as follows:
(X) + (X + 1) + (X + 2) = 228
To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 228
3X + 3 = 228
3X + 3 - 3 = 228 - 3
3X = 225
3X/3 = 225/3
X = 75
Which means that the first number is 75, the second number is 75 + 1 and the third number is 75 + 2. Therefore, three consecutive integers that add up to 228 are 75, 76, and 77.
75 + 76 + 77 = 228
We know our answer is correct because 75 + 76 + 77 equals 228 as displayed above.
The number is fairly easy to come across. The first thing that I see is that there are 45 students at the camp. This means, based on the clues given to me, that the number of 6th graders is odd. Because the number of 6th graders is half the number of 7th graders, and 8th grade equals 7th grade, that you have to use an even number less than 20, but more than ten.This leaves the numbers 14 and 18. Now we use trial and error. Half of 14 is 7. 14+14=28
28+7=35
35≠45
Half of 18 is 9.
18+18=36
36+9=45
45=45
So the answer is as follows:
6th grade: 9
7th grade: 18
8th grade: 18
