Answer:

$5x+80=180$
I hope this helps and that you can give a brainliest!

Step-by-step explanation:

This is a straight line which is always 180°.

Here there are 3 angles adding up to the total 180°.

So the initial equation is $3x+80+2x =180$ .

But there are coefficients that share the same variable.
So by simplifying the equation, you end up with:

$5x+80=180$

Jon caught four fish that weighed a total of 252 pounds. The kingfish weighed twice as much as the amberjack and the white marli

Allushta [10]

Answer:

amberjack, 21 lbs
kingfish, 42 lbs
white marlin, 84 lbs
tarpon, 105 lbs

Step-by-step explanation:

Let k, a, m, t represent the weights of the kingfish, amberjack, marlin, and tarpon, respectively. The problem statement tells us ...

k = 2a
m = 2k
t = 5a
k + a + m + t = 252

Using substitution, we can rewrite the last equation as ...

... (2a) + (a) + 2(2a) + (5a) = 252

... 12a = 252 . . . . . collect terms

... a = 21 . . . . . . . . .divide by 12

Then k = 2a = 42; m = 2k = 84; t = 5a = 105.

Least common denominator of 6/7 and 5/14

Darya [45]

Answer:

Step-by-step explanation:

You can‘t simplify 5/14 because 5 is a prime number. So, now you have to convert the 6/7 to 12/14 to match it up to 5/14. They now have a common denominator of 14.

Hope this helps! :)

Para armar un escritorio, Eduardo tendrá que usar 20 tarugos, los que debe cubrir completamente con una capa de pegamento. Él ca

Degger [83]

El área superficial total de los veinte tarugos es mayor que el área superficial cubierta por el pegamento.

<h3>Como determinar si la superficie cubierta por el pegamento es suficiente</h3>

En esta pregunta debemos calcular el área superficial total de los tarugos ( $A_{s}$ ), en milímetros cuadrados, y comparar el resultado con la cifra afirmada por Eduardo. El área superficial total es:

$A_{s} = 20\cdot \pi\cdot (5\,mm)^{2}\cdot (80\,mm)$

$A_{s} \approx 125663.706\,mm^{2 }$

En consecuencia, el área superficial total de los veinte tarugos es mayor que el área superficial cubierta por el pegamento. Francisca tiene la razón. $\blacksquare$

<h3>Observación</h3>

El enunciado omite las dimensiones <em>geométricas</em> de cada tarugo (5 milímetros de radio y 80 milímetros de longitud).
