What must be subtracted from each term of the ratio 3:7 so that the ratio becomes 2:5?

My attempt: Let two numbers be 3x and 7x. So, 3x−y7x−y=25⟹15x−5y=14x−2y⟹y=x3. But the answer is given as 13 only.

I wish somebody could provide some clarifications.

Answer:

13.

Step-by-step explanation:

I think you meant to write 25:37.

The answer is:

13 as

25 - 13 = 12

and 37 - 13 = 24

12: 24 = 1:2.

Answer:

The answer would be A)98.

I got this by taking the 3 test scores that were provided and adding them then subtracting that by 360 (90x4 - which would give you a 90 in the end) so I had 360 - 262 which equaled 98 and that would be the score needed to have a 90 in the end.

Which choice is equivalent to the quotient shown here when x is greater than or equal to 0?

Dima020 [189]

Answer: OPTION C

Step-by-step explanation:

Remember that:

$\sqrt[n]{a^n}=a$

And the Product of powers property establishes that:

$a^m*a^n=a^{(mn)}$

Rewrite the expression:

$\frac{\sqrt{18x} }{\sqrt{32} }$

Descompose 18 and 32 into their prime factors:

$18=2*3*3=2*3^2\\32=2*2*2*2*2=2^5=2^4*2$

Substitute into the expression, then:

$\frac{\sqrt{(2*3^2)x} }{\sqrt{2^4*2} }$

Finally,simplifying, you get:

$\frac{3\sqrt{(2)x} }{2^2\sqrt{2} }=\frac{3\sqrt{2x}}{4\sqrt{2}}=\frac{(3)(\sqrt{x})(\sqrt{2})}{(4)(\sqrt{2})}= \frac{3\sqrt{x}}{4}$
