Solve x − 2y = 3 for x.

Mathematics
2 answers:
Ann [662]3 years ago

Answer:

x = 3 + 2y

Step-by-step explanation:

This is the answer because:

1) First, you have to isolate x, in order to isolate x you have to bring x to the end of the equation.

2) Then, you have to add 2y to both sides of the equation.  

Another way you can think of this is:

1) If you add 3 + 2y you would figure out the answer because if you want to find x for a subtraction equation, you can add the answer to the equation with the number.

For example, x - 20 = 10, now to figure this equation out, you can either isolate the x, or you can add the answer in the equation with the remaining number in the equation.

Hope this helps!

Answer:

x=2y+3

Step-by-step explanation:

So we have the equation:

x-2y=3

And we want to solve for x. In other words, we want to isolate the x-variable.

So, add 2y to both sides of the equation.

(x-2y)+2y=(3)+2y

On the left, the 2y cancel. Simplify the right:

x=2y+3

And we're done!

Ritz can eat 8 apples in 15 minutes. How long does it take Ritz to eat 16 apples at the same rate?
natka813 [3]
The rate Ritz can eat apples is 8/15 apples per minute.

Set the rate (which is measured apples / minutes) equal to 16 apples / t minutes.

(8/15) = (16/t)

Cross multiply.

16*15 = 8t

t = 20

The answer is 30 minutes. You could solve the problem with basic reasoning as well. 16 is twice the number of apples as 8, so the time it takes to eat them will be double 15 minutes.

F = 1.8C + 32 what is c
zepelin [54]

Step-by-step explanation:

right.

and therefore c is in this case the name of the variable in the equation (or function).

add on.

ah, do you mean (and does this strange problem description mean) that you want the reverse formula : to get C out of F ?

in that case

F = 1.8c + 32 = 9/5 × c + 32

F - 32 = 9/5 × c

5/9 × (F - 32) = c

or

c = 5/9 × (F - 32)

that's it.
