First, let's do the numerator! 4.8 - 0.24 = 4.56. Now, let's simplify the denominator. 0.2 * 0.6 = 0.12

4.56 / 0.12 = 38

Hope this helps :)

7^16/7^12=7^-18/? what is the missing denominator

creativ13 [48]

$\bf \left.\qquad \qquad \right.\textit{negative exponents}\\\\
a^{-{ n}} \implies \cfrac{1}{a^{ n}}
\qquad \qquad
\cfrac{1}{a^{ n}}\implies a^{-{ n}}
\qquad \qquad 
a^{{{ n}}}\implies \cfrac{1}{a^{-{{ n}}}}\\\\
-------------------------------\\\\$

$\bf \cfrac{7^{16}}{7^{12}}=\cfrac{7^{-18}}{x}\implies x\cdot 7^{16}=7^{12}\cdot 7^{-18}\implies x\cdot 7^{16}=7^{12-18}
\\\\\\
x\cdot 7^{16}=7^{-6}\implies x=\cfrac{7^{-6}}{7^{16}}\implies x=\cfrac{7^{-6}\cdot 7^{-16}}{1}\implies x=7^{-6-16}
\\\\\\
\boxed{x=7^{-22}}\implies x=\cfrac{1}{7^{22}}$

2x+3y=23<br> 3x-y=7<br> Solve for x

NeTakaya

2x + 3y = 23...........................(1)

3x - y = 7 Multiply by 3:-

9x - 3y = 21 Adding this to equation (1):-

11x = 44
x =

Plug this into equation (1):-
2(4) + 3y = 23

3y = 15
y = 5

Answer is x = 4, y = 5
