Lesechka [4]3 years ago

Answer:

\displaystyle x   = 2 \sqrt{3}

Step-by-step explanation:

we would like to solve the following equation:

\displaystyle  \sqrt{3}  =  \frac{6}{x}

in order to do so do cross multiplication:

\displaystyle x \sqrt{3}  =  6

divide both sides by √3:

\displaystyle x   =   \frac{6}{ \sqrt{3}}

since we ended up with a square root on the denominator so we can consider rationalising the denominator to do so multiply both numerator and denominator by √3 which yields:

\displaystyle x   =   \frac{6}{ \sqrt{3}}  \times  \frac{ \sqrt{3} }{ \sqrt{ 3} }

simplify multiplication:

\displaystyle x   =   \frac{6 \sqrt{3} }{ 3}

reduce fraction:

\displaystyle x   = 2 \sqrt{3}

and we are done!

Please help solve the equation above.
Paladinen [302]

Answer:

x=12

Step-by-step explanation:

(9x-4)+(5x+16)=180

14x+12=180

     -12    -12

14x=168

then devide both sides by 14

x=12

The rate of change for the graph would be the last option, 35. If you follow rise over run, you end up with a rise of 35 and a run of 1, or 35/1 which simplifies to 35.

At the bank, Derek made 7 withdrawals, each in the same amount. His brother, John, made 5 withdrawals, each in the same amount.
lozanna [386]

Answer:

x=12.50

y = 17.50

Step-by-step explanation:

x = Amount of one Derek withdrawal

then amount of John withdrawal =x+5

Total withdrawals of Derek = no of times x one time withdrawal

= 7(x) = 7x ... i

No of John withdrawal = no of times x one time withdrawal

= 5(x+5)  ... ii

Given that i and ii are equal

i.e. 7x =5(x+5)

7x = 5x+25

2x =25

x = 12.50 dollars

Y = 17.50 dollars

Checking part:

total derek withdrawal = 7(12.5) =87.50

Joh's withdrawal = 5(17.50) = 87.50

Since both are equal, our answers are right.

Solution:  Derek withdrew each time 12.50 dollars each for 7 times and John withdrew 17.50 dollars each for 5 times.
