Hi!
These two angles are alternate interior angles, so they are congruent. Thus:
∠A = ∠B
6x + 5 = 4x + 45
Solve for x:
2x + 5 = 45
2x = 40
x = 20
Solve for ∠A by substituting in this value:
∠A = 6(20) + 5 = 125°
9514 1404 393
Answer:
x+y<20andx+5y>40
Step-by-step explanation:
The inequality for the number of coins is ...
x + y < 20
The inequality for the value of the coins is ...
x + 5y > 40
Answer:
15 students
Step-by-step explanation:
25% = 1/4, so you can just do 1/4 of 60 or 1/4 * 60. 60/4 = 15 students.
Answer:
About $9.65.
Step-by-step explanation:
Cost divided by quantity.
A number raised<span> to a </span>negative power<span> is equal to 1 divided by the </span>number raised<span> to the same </span>power<span> but positive
</span>therefore
[-1/2]^-3-----------> [-2]^3 =-8
the answer is [-1/2]<span>^-3
