Question

how do you find the value of 24xyz

Answer 1

we need more info

Answer 2

so the question was 2x=5
3y=4
4z=3 what is the value of 24xyz

Answer 3

solve for x
solve for y
solve for z
then tell me what x=? y=? z=?
like this
2x=5 so x=5/2

Answer 4

so do the same thing for y, and z.

Answer 5

you could also multiply the left sides together

then multiply the right sides together

Answer 6

that's prob more clever way yes;)

Answer 7

@RebaLynn do you see what he means?

Answer 8

(2x)(3y)(4z) = (5)(4)(3) ?

Answer 9

2x=5
3y=4
4z=3
multiply everything on the left hand sides 2x*3y*4z = 24xyz and since we multiplies everything on the left hand sides, this will equal what we get when we multiply the right hand sides

Answer 10

so I just divide 2x\5 and get the value of x

Answer 11

that is one way

method one
2x=5
3y=4
4z=3
so x=5/2, y=4/3, z=3/4
so
24xyz=24(5/2)*(4/3)*(3/4) = (24*5*4*3)/(2*3*4) = 12*5 = 60

method two
multiply the left hand sides and the right hand sides together
(2x)(3y)(4z) = (5)(4)(3)
24xyz=60

Answer 12

So just find the value of xyz. and then plug it in to find 24(xyz)

Answer 13

if the average of 5 numbers is 10 and the fitfth number Is 6 then what is the average of the first 4 numbers

Answer 14

average is the sum of all the number DIVIDED by the amount of numbers...so if the average of 5 numbers is 10, multiply 10 by 5, which would give you that the SUM of the 5 numbers is 50
now if the 5th number is 6, you SUBTRACT 6 from 50 to get that the first 4 numbers add up to 44..now just divide by 4 to get the average of the first FOUR numbers...so the average of the first four numbers would be 11 :)
