Hello there!

To make x the subject of the formula, we need to start by doing "Cross multiply"

(y)(x) = a

yx = a

Solve for x

Divide both sides by y

yx/y = a/y

x = a/y

Good luck with your studies!

Answer:

F. 5:4

Step-by-step explanation:

Solve for a and c to find the ratio of a to c:

2a = 3b
a = 3/2(b)
6b = 5c
c = 6/5(b)

Now, we can use the value of a and c to find the ratio of a to c:

(3/2(b))/(6/5(b))
3b/2 × 5/6b
15b/12b
5/4

F. 5:4 is the correct answer

Determine whether or not the two equations below have the same solution. In two or more complete sentences, explain your rationa

Dimas [21]

These equations do match up. All you have to do is find the solution to the first equation. After that, plug in that solution to the second equation. If it makes the equation true, then the equations match.

Hope this helps!

laila [671]

Answer:

I'm going to assume that the binder is $10, and that the tax is applied after the 60% off, in which case the answer is $4.24

Step-by-step explanation:

10 * 10 = 100

6 * 10 = 60

10 - 6 = 4

6 / 25 = 0.24

4 + 0.24 = 4.24
