Answer:

x+y+z-2t

Step-by-step explanation:

There are t students taking all three and the rest take only 1 language.

The number taking only Oriya is x-t .

The number taking only Dakhini is y-t .

The number taking only Dutch is z-t .

So the number of students altogether is

x-t + y-t + z-t + t = x+y+z-2t.

Hope this helps! :D

X+y+z=t
simple..
there are no other numbers that we have to follow like (1/2x or 3/4y) so it is just all together=t. the x, y, z will equal t because t is the total number of students taking three languages. And that number should be equivalent to x,y,z combined.

otherwise?? i d k

What are the steps to 68 times 49

Anastaziya [24]

so basically what you would have to do is set up your numbers. it would look something like this. 68

× 49

-------------

and would then multiply 9 by 8, 9 by 6. put it down below the line while making sure to carry the numbers if need be. then do the same with the 4 times 8, and 4 by 6.

Rachel's cell phone company charges $0.10 per minute. She used 350 minutes last month and paid $84. writ and solve a linear equa

dimaraw [331]

Answer:

Step-by-step explanation:

cuz,
x equals the number of minutes so use the y slope formula

0.10(x)+the intercept = y
0.10(350)+the intercept = 84
35+the intercept = 84
the intercept = 49
so the equation is
0.10(x)+49 = y
or
1/10(x)+49 = y
1/10(300)+49=y
30+49=y
79=y
so the answer is 79 dollars
