Answer:
12 adults
Step-by-step explanation:
We can solve this in a couple of simple steps. First, since there are 3 adults for every 8 students we add these two numbers together
3+8 = 11
Now we simply divide this number by the total amount of people that went to the trip in order to get how many times this set of adults and students repeats itself.
44 / 11 = 4
Finally, we multiply this number by the set of 3 adults in order to find out how many adults went to the trip.
4 * 3 = 12 adults
8 * 3 = 32 Students
Answer:
(1, - 2 )
Step-by-step explanation:
Given the equations
9x + 2y = 5 ( subtract 9x from both sides )
2y = 5 - 9x ( divide terms by 2 )
y = 2.5 - 4.5x → (1)
7x - 3y = 13 → (2)
Substitute y = 2.5 - 4.5x into (2)
7x - 3(2.5 - 4.5x) = 13
7x - 7.5 + 13.5 = 13 , that is
7x + 6 = 13 ( subtract 6 from both sides )
7x = 7 ( divide both sides by 7 )
x = 1
Substitute x = 1 into (1) and evaluate for y
y = 2.5 - 4.5(1) = 2.5 - 4.5 = - 2
solution is (1, - 2 )
Part 1) <span>angles congruent to <1
we know that
</span><4=<1-------> by vertical angles
<5=<1-------> by corresponding angles
<8=<5------> by vertical angles or <8=<1 ----> by alternate exterior angles
so
the answer part 1) is
<span><4,<8,<5
</span>
Part 2) <span>angles congruent to <2
</span>we know that
<3=<2-------> by vertical angles
<6=<2-------> by corresponding angles
<7=<6------> by vertical angles or <7=<2 ----> by alternate exterior angles
so
the answer part 2) is
<span><3,<7,<6
</span>
Part 3)<span>angles congruent to <7
</span>we know that
<6=<7-------> by vertical angles
<3=<7-------> by corresponding angles
<2=<3------> by vertical angles or <2=<7 ----> by alternate exterior angles
so
the answer part 3) is
<span><3,<6,<2
Part 4) </span><span>angles congruent to <6
</span>we know that
<7=<6-------> by vertical angles
<2=<6-------> by corresponding angles
<3=<2------> by vertical angles or <3=<6 ----> by alternate interior angles
so
the answer part 4) is
<span><3, <7, <2</span>
Answer:
Step-by-step explanation:
f(3)=2*3^2 - 3*3^2 + 1
=2*9 - 3*9 + 1
=18-27+1
=19-27
