How do I convert 82.1, 7.3, 9.3 in a fraction form
nalin [4]

Answer:

Step-by-step explanation:

82.1 = 82 1/10 (thats 82 and 1/10) or 821/10 (if you dont want a mixed number)

7.3 = 7 3/10 or 73/10

9.3 = 9 3/10 or 93/10

if there is 1 number to the right of the decimal, put that number over 10....not the whole number, just the number to the right of the decimal. Leave the number to the left of the decimal alone.

if there were 2 numbers to the right of the decimal, then put those two numbers over 100.

example :

3.43 = 3 43/100

2.76 = 2 76/100

if there were 3 numbers to the right of the decimal, put those 3 numbers over 1000

example :

2.347 = 2 347/1000

3.679 = 3 679/1000

you understand ?

What is the first step in solving this system by elimination?
kherson [118]

You want to try and get rid of one of the variables ( x or y) so you would multiply the second equation by 2 which would make the x variable -2x which then when added to the first equation would eliminate the x variable.

Answer: c. Multiply the second equation by 2.

Plz help me with this
zvonat [6]

Answer:  5 cos x

<u>Step-by-step explanation:</u>

y = sin x     is       y = cos x        shifted to the right π/2 units.

y = 5 sin (x + π/2)     is a shift to the left π/2 units (which results in cos x) and    .                                 an amplitude of 5.

--> y = 5 cos x
