Answer:

$\boxed{\bold{c=\frac{3}{5}}}$

Equation:

$\bold{5c+16.5=13.5+10c}$

Step By Step Explanation:

Subtract 16.5 From Both Sides

$\bold{5c+16.5-16.5=13.5+10c-16.5}$

Simplify

$\bold{5c=10c-3}$

Subtract 10c From Both Sides

$\bold{5c-10c=10c-3-10c}$

Simplify

$\bold{-5c=-3}$

Divide Both Sides By -5

$\bold{\frac{-5c}{-5}=\frac{-3}{-5}}$

Simplify

$\bold{c=\frac{3}{5}}$

$\boxed{\bold{\bullet{} \ Mordancy \bullet{}}}$

Answer:

c = 3/5

Step-by-step explanation:

5c+16.5=13.5+10c

Subtract 5c from each side

5c-5c+16.5=13.5+10c-5c

16.5 = 13.5 +5c

Subtract 13.5 from each side

16.5 -13.5 =13.5-13.5 +5c

3 = 5c

Divide by 5

3/5 = 5c/5

3/5 =c

Answer:

first answer is correct

Step-by-step explanation:

Hello, we want to write 2 + 4 + 6 + ... + 20

for n = 1, 2n = 2*1 =2

for n = 2, 2n = 2*2=4

for n = 3, 2n=2*3=6

etc

$\displaystyle \sum_{n=1}^{10} {2n} = 2*1 + 2*2 +2*3+2*4+...+2*10=2+4+6+8+...+20$

thanks

Using the Law of Cosines, in triangle DEF, if e=18yd, d=10yd, f=22yd, find measurement of angle D

Ivahew [28]

Check the picture below.

$\bf \textit{Law of Cosines}\\ \quad \\
c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\implies 
c = \sqrt{{{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)}
\\\\\\
\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}=cos(C)\implies cos^{-1}\left(\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}\right)=\measuredangle C\\\\
-------------------------------\\\\
\begin{cases}
d=10\\
e=18\\
f=22
\end{cases}\implies cos^{-1}\left(\cfrac{{{ 18}}^2+{{ 22}}^2-10^2}{2(18)(22)}\right)=\measuredangle D$

$\bf \implies cos^{-1}\left(0.893\overline{93}\right)=\measuredangle D\implies 26.63^o\approx \measuredangle D$
