If you distribute the negative sign on the right hand side, you have

$x+y-1=1-(1-x) \iff x+y-1=1-1+x \iff x+y-1=x$

You can simplify $x$ from both sides:

$y-1=0$

And if you add 1 to both sides, you have

$y=1$

A box contains 146 marbles which are either red or blue. there are 28 more blue marbles than red marbles. how many blue marbles

rusak2 [61]

R + b = 146. Supposing that b=r+28,

r + (r+28) = 146, or 2r + 28 = 146.

Simplifying: 2r = 118. Then r = 59, and b = r+28 = 59+28 = 87 blue marbles

Brad says that if a second number is 125% of the first number than the second number must be 75% of the second number is he corr

elena-s [515]

Answer:

Incorrect.

Step-by-step explanation:

Let, the first number is x, and the second number is y. Given, the second number is 125% of the first number. So, the equation will be

y = 1.25 x

Or, y= 5/4x

Now, multiplying it with 4/5, we get, x= 4/5y

Or, x= 0.80 y

But, Brad is saying the first number must be 75% of the second number. But here we see that the first number is 80% of the second number. That's why Brad is incorrect.
