4x+y=1
y=x+6
4x+(x+6)=1
5x+6=1
5x=5
x=1
y=(1)+6
y=7
(1,7)

1/5= 6x and 1/3= 10x

Lady bird [3.3K]

Answer:

1/30

Step-by-step explanation:

1/5 = 6x ....divide both sides by 6

(1/5) / 6 = x

1/5 * 1/6 = x

1/30 = x

1/3 = 10x...divide both sides by 10

(1/3) / 10 = x

1/3 * 1/10 = x

1/30 = x

so x = 1/30

Factor of 4-(2a+3b)^2

Anna71 [15]

$4-(2a+3b)^2$

$(2a+3b)^2 :$

$4a^2+12ab+9b^2$

$= 4-(4a^3+12ab+9b^2)$

$=-(4a^2)-(12ab)-(9b^2)$

apply minus - plus rules :

$+(-a)=-a$

Refine:

$=-4-4a^2-12ab-9b^2$

hope this helps!

Find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)

laila [671]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\quad 
\begin{cases}
r=radius\\
-----\\
A=452.16
\end{cases}\implies 452.16=\pi r^2\implies \cfrac{452.16}{\pi }=r^2
\\\\\\
\boxed{\sqrt{\cfrac{452.16}{\pi }}=r}\\\\
-------------------------------\\\\
\textit{circumference of a circle}\\\\
C=2\pi r\qquad \qquad \implies C=2\pi \left( \boxed{\sqrt{\cfrac{452.16}{\pi }}} \right)$

so, is just that product, recall to use "3.1416 as the value of π".
