Answer:
The answer to your question is:
Step-by-step explanation:
Q1. They are vertical angles, so they measure the same
[2(x + 10)] = (3x - 30)
2x + 20 = 3x -30
2x - 3x = -30 - 20
- x = - 50
x = 50
Q2. They are also vertical angles, so they measure the same.
[6(x - 2)] = 3x + 30
6x - 12 = 3x + 30
6x - 3x = 30 + 12
3x = 42
x = 42/3
x = 14
∠DHG = 6(14 - 2)
∠DHG = 6(12)
∠DHG = 72
First is y-4
2nd is z divided by 4
3rd is a4
4th is 4x
5 is b+4
Answer:
1/3
Step-by-step explanation:
In the coin there is heads or tails (2 possible results), so the probability of tossing heads is 1/2
For the number cube, we have 6 possible results. If we want a result greater than two, we have 3, 4, 5 or 6, so we have 4 of the 6 results, then the probability is 4/6.
Now, to find the final probability, we multiply both probabilities above:
Probability = (1/2) * (4/6) = 2/6 = 1/3
p(10) is the profit, in dollars, from selling 10 books. Replace every copy of x with 10 and simplify
p(x) = 8x-10
p(10) = 8*10-10 .... every x is replaced with 10
p(10) = 80-10
p(10) = 70
So the profit is $70
A regular polygon has about 5 lines of symmetry. The number of lines of symmetry is equivalent to the number of sides.
