Solve for x:5 x + 3 (x + 4) = -20
3 (x + 4) = 3 x + 12:3 x + 12 + 5 x = -20
Grouping like terms, 5 x + 3 x + 12 = (5 x + 3 x) + 12:(5 x + 3 x) + 12 = -20
5 x + 3 x = 8 x:8 x + 12 = -20
Subtract 12 from both sides:8 x + (12 - 12) = -12 - 20
12 - 12 = 0:8 x = -20 - 12
-20 - 12 = -32:8 x = -32
Divide both sides of 8 x = -32 by 8:(8 x)/8 = (-32)/8
8/8 = 1:x = (-32)/8
The gcd of -32 and 8 is 8, so (-32)/8 = (8 (-4))/(8×1) = 8/8×-4 = -4:Answer: x = -4
Tan(34) = a/700
a = 700*tan(34) =472.155 so 472
Answer:
if that line follows y=mx...then answer is A
But it seems not....when we divided valuse like 60/2=30
75/3=25....
ratio is not the same
Its hard to tell....You must know exact cordinations
I can tell you this
I can say this if y=60 and x=2 and....y=120 and x=4...then it is propotional...but it seems not..
Answer:
15/40 or simplified 3/8
Step-by-step explanation:
Answer:
(B) No. A binomial probability model applies to only two outcomes per trial.
Step-by-step explanation:
The binomial probability is the probability of having 
sucesses on 
repeated trials of an experiment that can only have two outcomes. This is why it is called the binomial probability.
Since in our problem there are three possible outcomes, the binomial probability cannot be used.
The correct answer is (B)
(B) No. A binomial probability model applies to only two outcomes per trial.
