Answer:

\frac{ \sqrt{5x} }{5x}

Step-by-step explanation:

\frac{1}{ \sqrt{x5} }

=  \frac{1}{ \sqrt{5x} }

=  \frac{1}{ \sqrt{5x} }  \times  \frac{ \sqrt{5x} }{ \sqrt{5x} }

=  \frac{1 \sqrt{5x} }{ \sqrt{5x \sqrt{5x} } }

=  \frac{\sqrt{5x} }{ \sqrt{5x \sqrt{5x} } }

= \frac{ \sqrt{5x} }{5x}

The word "solution" means . . .

88 is a solution to 1/8x=11 because . . .

Answer/Step-by-step explanation:

✔️The word solution means the value of the unknown variable, x. This means, when the value of x is substituted into the equation, the equation becomes balance as the value on the left equals the value on the right.

✔️88 is a solution to ⅛x = 11 because:

if we substitute x for 88 into the equation, both sides would be equal.

Avery and Caden have saved $27,000 towards a down payment on a house. They want to keep some of the money in a bank account that
Thepotemich [5.8K]

Answer:

$6750 in the bank account and $20,250 in the stock fund

Step-by-step explanation:

If B is the money they put in the bank and S is the amount they put in the stock fund, then:

B + S = 27000

1.024 B + 1.072 S = 1.06 × 27000

Solving the system of equations:

1.024 (27000 − S) + 1.072 S = 28620

27648 − 1.024 S + 1.072 S = 28620

0.048 S = 972

S = 20250

B = 27000 − S

B = 6750

They should put $6750 in the bank account and $20,250 in the stock fund.
