EASY MATH!!! GIVING BRAINLIEST!!

musickatia [10]

Answer:

Step-by-step explanation:

So lets take our 50 dollars.

Next, take your increase of 5%. Remember, 5% is 0.05, and it is a increase of 5%, so we are multipling 50 by 1.05.

Before we start multiplying, lets recall that this occurs twice(2 years), but this doesnt mean we multiply 50 by 1.10. No, we just mutiply 50 by 1.05 2 times:

50*1.05

52.5

52.5*1.05

55.25

So your answer is 55 dollars(rounding down).

Hope this helps!

What is the simplified form of StartRoot StartFraction 72 x Superscript 16 Baseline Over 50 x Superscript 36 Baseline EndFractio

aalyn [17]

Answer:

StartFraction 6 Over 5 x Superscript 10 Baseline EndFraction

Step-by-step explanation:

Apparently you want to simplify ...

$\sqrt{\dfrac{72x^{16}}{50x^{36}}}$

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

1/a^b = a^-b

(a^b)^c = a^(bc)

So the expression simplifies as ...

$\sqrt{\dfrac{72x^{16}}{50x^{36}}}=\sqrt{\dfrac{36}{25x^{36-16}}}=\sqrt{\dfrac{36}{25x^{20}}}\\\\\sqrt{\left(\dfrac{6}{5x^{10}}\right)^2}=\boxed{\dfrac{6}{5x^{10}}}$

What is Y-3x=-2 and Y+x=-6

love history [14]

Rearranging the first equation gives:

$y=3x-2$

Substituting this into the other equation gives:

$y+x=-6
\\(3x-2)+x=-6
\\4x-2=-6
\\4x=-4 \\x=-1$

If x=-1:

$y+(-1)=-6
\\y=-5$

So x=-1, y=-5
