Answer: 1=x
Step-by-step explanation:
34-7x=15+12x
Add 7x to both sides of equation because the oppisite of -7x is +7x
34-7x+7x=15+12x+7x
34=15+19x
Subtract 15 from both side of equation because the oppisite of 15 is -15
34-15=15-15+19x
19=19x
Divide both sides by 19 to get x alone
19/19=19x/19
1=x
Answer:
mBC = 96°
mB = 55°
mC = 77°
mAB = 154°
Step-by-step explanation:
The angle mB inscribes the arc mAC, so we have:
The sum of internal angles of a triangle is 180°, so in the triangle ABC we have:
Using again the property of inscribed angles, we have:
Answer:
3(-8 + 1) = 3(-8) + 3(1)
Step-by-step explanation:
The distributive property is quite literally when you distribute numbers. This is the only instance of that happening here
The first two are the communitive property of addition, and the last one is the communitive property of multiplication.
