5y-30=-5y+30 and also can you show the steps :}

KatRina [158]

5y-30=-5y+30

add 30 to both sides

5y = -5y+60

add 5y to both sides

10y = 60

divide both sides by 10

y = 6

Sally is 10 years older than one fifth of her mother’s age. If Sally is 20 years old, how old is her mother?

slamgirl [31]

S = Sally

M = Mother

S = M/5 + 10

20 = M/5 + 10

20 - 10 = M/5

10 = M/5

M = 10 * 5

M = 50

----------------

Her mother is 50 yo

-----------------

50 : 5 + 10 = 20

the answer is good

anastassius [24]

The product below is equivalent when x > 0 is <u>1/9</u>

<h3>Resolution - Explanation</h3>

Square root is a real number x multiplied by itself - which results in a perfect value, where it is possible to calculate the real proof (which is the square root).

Given the expression, $\large \sf \sqrt{\dfrac{1}{x^{2} } } \cdot \sqrt{\dfrac{x^{2} }{81} }$ , first step: we will calculate the root of the numerator and denominator of this fraction:
