Solve for x 70° * 20 triangles

dalvyx [7]

Answer:

x = 90°

Step-by-step explanation:

a triangles angles are equal to 180°

so if we have one that is 70° and one that is 20° what s x?

70° + 20° = 90°

180° - 90° = 90°

x = 90°

3(n+4) =1/2 (6n+4) step by step

Pavlova-9 [17]

3(n+4)=1/2(6n+4)
2x3(n+4)=2x1/2(6n+4)
6(n+4)=1(6n+4)
6n+24=6n+4
24-4=6n-6n

Alg 1 solving equations -12(-4 + p) = -48

Vilka [71]

Answer:

$p=8$

Step-by-step explanation:

$-12\left(-4+p\right)=-48$

Divide both sides by -12:-

 $\frac{-12\left(-4+p\right)}{-12}=\frac{-48}{-12}$

$-4+p=4$

Add 4 to both sides:-

$-4+p+4=4+4$

$p=8$

Write an equation in standard form of the line With slope 2/5 and going through (-3,6).

german

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

$(\stackrel{x_1}{-3}~,~\stackrel{y_1}{6})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{2}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{6}=\stackrel{m}{\cfrac{2}{5}}(x-\stackrel{x_1}{(-3)})\implies y-6=\cfrac{2}{5}(x+3)$

$y-6=\cfrac{2}{5}x+\cfrac{6}{5}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{5}}{5(y-6)~~ = ~~5\left( \cfrac{2}{5}x+\cfrac{6}{5} \right)}\implies 5y-30~~ = ~~2x+6 \\\\\\ -2x+5y-30=6\implies -2x+5y=36\implies 2x-5y=-36$
