Answer: j = 38

Step-by-step explanation: First isolate j/-2 by subtracting

7 from both sides of the equation.

That gives you j/-2 = -19.

From here, since j is being divided by -2, multiply

both sides of the equation by -2 so <em>j = 38</em>.

Answer:

$\huge\boxed{j=38}$

Step-by-step explanation:

$\dfrac{j}{-2}+7=-12\qquad\text{subtract 7 from both sides}\\\\\dfrac{j}{-2}+7-7=-12-7\\\\\dfrac{j}{-2}=-19\qquad\text{multiply both sides by (-2)}\\\\(-2)\!\!\!\!\!\!\!\diagup\cdot\dfrac{j}{-2\!\!\!\!\!\diagup}=(-2)(-19)\\\\j=38$

Answer:

1) $65\textdegree$

2) $44\textdegree$

3) $107\textdegree$

4) $82\textdegree$

Step-by-step explanation:

1) Since the whole angle is $180\textdegree$ , and to find the other angle, which is labeled as $x$ , you subtract $115\textdegree$ from $180\textdegree$ :

$180 - 115 = 65$

$x = 65\textdegree$

2) Since you already have two angle measures $46\textdegree$ and $90\textdegree$ , you add them up and subtract it from $180\textdegree$ to get the angle measure for $x$ :

$46 + 90 = 136$

$180 - 136 = 44$

$x = 44\textdegree$

3) Same thing from number 1. Subtract $73\textdegree$ from $180\textdegree$ :

$180 - 73 = 107$

$x = 107\textdegree$

4) Same thing from number 2. Add $52\textdegree$ and $46\textdegree$ and subtract it from $180\textdegree$ :

$52 + 46 = 98$

$180 - 98 = 82$

$x = 82\textdegree$

Is x = -12 a solution of x^2 +10x+25=49?

Tresset [83]

Answer:

Yes

Step-by-step explanation:

${x}^{2} + 10x + 25 = 49 \\ {x}^{2} + 10x + 25 - 49 = 0 \\ {x}^{2} + 10x - 24 = 0 \\ (x + 12)(x -2 ) = 0 \\ \\ x + 12 = 0 \\ x = - 12 \\ \\ \\ x - 2 = 0 \\x = 2$

I hope I helped you^_^
