There are 26 third graders and 32 fourth graders going on a field trip. each van carry 10 students. how many students are needed? how many students will be in each van?

We need 6 vans, in 5 of those we will have 10 students, and in the other van, we will have 8 students.

Step-by-step explanation:

The data is:

We have 26 third graders

We have 32 fourth graders

We have a total of 26 + 32 = 58 students.

We know that in each van we can have a max of 10 students, so we want to find the number X of vans that we need.

This is the maximum number of seats in the X vans is X*10

so we must have X*10 = 58

X = 58/10 = 5.8

but we can not have a 0.8 of a van, so we need to round up to 6, we need 6 vans.

And we will have that 5 of those vans are completed with 10 students each, and the last van only carries 8 students, (5 times 10 = 50, + 8 in the last van is 50 + 8 = 58, which is the number of students)

answer: lol haha i'm in flvs too!

but to answer question number 1 would be a.

and number 2 would be c.

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
