The reciprocal of 2/3 is 3/2. If the reciprocal of 4x/5 is 1/20, what is x?

1 answer:

6 0

Since 4x/5 is the reciprocal of 1/20, that means that 4x/5 = 20/1, or 20. Using this info, we can form the equation $\frac{4x}{5}=20$ . From there we can solve for x.

Firstly, multiply both sides by 5: $4x=100$

Next, divide both sides by 4 and your answer will be $x=25$

Finding the X-intercept.

1.) Solve for x by substituting 0 in for y.

4x+(0)=5

4x/4+5/4

x=1.25 or 1 and 1/4.

Answer:

j=38

Step-by-step explanation:

j/-2 +7=-12, subtract 7 from both sides of the equation and you get j/-2 = -19, then you multiply j/-2 by -2/1 and multiply -19 by -2/1 to get j= 38
