Answer:

Step-by-step explanation:

A + B = 90

6 - 5x + 7 - 2x = 90

13 - 7x = 90

- 7x = 90 - 13

- 7x = 77

- x = 77 / 7

x = - 11

A: 6 - (5 * - 11) = 6 + 55 = 61

B: 7 - (2 * -11) = 7 + 22 = 29

Together they equal 90 as they should.

Use the product property of exponents to justify that (9^1/2)^2=9

WARRIOR [948]

The rule states that

$(a^b)^c = a^{bc}$

So, in your case, you have

$(9^{\frac{1}{2}})^2=9^{\frac{1}{2}\cdot 2}=9^1=9$

5/4+x=3/4 how do I figure this out

Andreyy89

You could subtract 5/4 from each side of the equation.
Then it would say
x = -2/4 .

That's a perfectly true solution, but not a very attractive one.
To pretty it up, you could simplify the fraction if you felt like it,
and you would have
x = -1/2 .

Xy+4y=3x-2, show that y is a function of x

zepelin [54]

(xy+4y)/x = (3x-2)/x
(y+4y)/x = (3x-2)/x divide both side by x
5y /x = (3x-2)/x
5y= 3x-2 Mult by x both side
y= (3x-2)/5
