Answer:
n = - 10
Step-by-step explanation:
10(-3n + 8) = 380
-30n + 80 = 380
80 - 380 = 30n
30n = - 300
n = - 300 : 30
n = - 10
Answer:
c
Step-by-step explanation:
4 times 2 is 8. 3 and 3 times -4 is -12
8 minus -12 is negative 4
2x-4y=8 --> (4y=-2x+8)/2 ---> (2y=-x+4)/2 --> y=-1/2+2
slope is -1/2 domain is (2, 0)
Answer:124
Step-by-step explanation:
2x + 8 + x - 2 = 180
Add like terms
3x + 6 = 180
Subtract the 6 from both sides
3x + 6 - 6 = 180 - 6
3x = 174
Divide by 3
x = 58
Now we have to find the measure of angle ACD
2(58) + 8 = 124
Step-by-step explanation:
We can simplify this to be (78+78)(84+16)
We calculate from here
(156)(100)
Bracket means multiplication so we multiply
=15,600
