After spending $30 on a dress, Mary had 3/8 of her money left. How much money did she have at first?
BaLLatris [955]
The answer is that she had 48.  Set it up as an equation with x as the amount of money she started with.  x - 30 = 3/8x.  That says, in words, "the amount of money she started with minus 30 for the dress left her with 3/8 of the money she started with.  Solve for x by adding 30 to both sides and subtracting 3/8 from 8/8x (8/8 = 1).  8/8 - 3/8 = 5/8, so 5/8x = 30, multiply both sides by 8 to get 5x=240 and x = 48.

Suppose for some value of x the solution to the equation 2.5(y−x)=0 is y = 6. What must be true about x?
Varvara68 [4.7K]

Step-by-step explanation:

In this case, you input the value of y (y = 6) into the equation ( 2.5(y-x)= 0)

2.5(6-x) = 0

Open the bracket,

(2.5×6)-2.5x= 0

Collect like terms.

2.5x= 2.5×6

Divide both sides by the coefficient of x (2.5)

x = 6

So,

x= 6 is true.

.

Substituting 6 for x in the equation,

2.5(6-6)= 0

2.5•0 = 0

0= 0

Which is also true.
