Sample answer from plato
Answer:subtract by 4x on each side first
Step-by-step explanation:
When you do so you'll get 5x on the left side of the equal sign and -5 on the right side. Next you would divide by 5 on both sides and this gives you x on the left side and -1 as your answer on the right side.
Answer:
Start by subtracting 3t from both sides of your equation
13t+4=12+3t
-3t. -3t
that gives you
10t+4=12
Subtract 4 from both sides
10t+4=12
-4. -4
That gives you
10t=8
Divide both sides by 10 to leave the variable by itself
10t=8
÷10. ÷10
That leaves you with
t=8/10 or t= 4/5 if you simplify.

Answer:
71°
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
∠H = 180° -109° = 71°
_____
<em>Additional comment</em>
The above rule comes from the more general rule that the measure of an inscribed angle is half the measure of the arc it intercepts. Here, inscribed angle J intercepts arc GHI, so that arc has measure 2×109°. Then the measure of short arc GI is 360° -2×109°, and inscribed angle H is half that:
∠H = (1/2)(360° -2×109°)
∠H = 180° -109° = 71°
