How do i solve -4(9-7x)-(1-x)=4(x-6)

Mathematics
1 answer:
olga2289 [7]3 years ago
6 0

Answer:

x = 13/25

Step-by-step explanation:

- 4 (9 - 7x) - (1 - x) = 4 (x - 6)

- 36 + 28x - 1 + x = 4x - 24

28x + x - 4x = - 24 + 36 + 1

25x = 13

x = 13/25

The remote interior angles of a triangle are basically the two angles that do not share a vertex with and are opposite to the exterior angle.

5. ∠1 and ∠2
6. ∠2 and ∠3
7. ∠1 and ∠3

Because the exterior angle of a triangle is equal to the remote interior angles we can set up the following equations:
8.
x + 80 = 105 \\ x = 105 - 80 \\ x = 25
9.
x + 72 = 135 \\ x = 135 - 72 \\ x = 63

So this has to do with permutations and honestly I need an explanation on how I can figure these out.
AnnZ [28]
Well, the answer quite simple ....there are 4! ways to arrange these numbers...and as 4! = 4*3*2*1 = 24

hence 24 is the correct answer....


u can also remember it by theorem of multiplication as.....in first place (I.e. first code can be any no. out of 4,5,2&7 ....so 4*.....

as first place is acquired by a certain no. that leaves three no. to fill third place and when third place I'd occupied it leaves 2 numbers to fill second place and lastly only one no. to fill the last place .....so it's result will be like 4*3*2*1.



I know this is pretty much confusing ....but still I tried my best....

if anything troubles u here feel free to ask me
