I think the answer is 43.8.
Answer:
C 4
Step-by-step explanation:
2 1/8 = 1 gift
4 2/8 = 2 gifts
6 3/8 = 3 gifts
8 4/8 = 4 gifts
10 5/8 would equal 5 gifts but bobby does not have that extra 5/8 of wrapping paper to finish it so he can only fully wrap 4 gifts.
U have to use Pythagoras theorem to solve this.. (adjacent)^2+(opposite)^2=hypotenuse^2
looking at the question,
the hypotenuse =15ft
opposite =12ft
adjacent =???
adjacent^2+(12)^2=15^2
a^2+144=225
group like terms
a^2=225-144
a^2=81
introduce square root to both side
root a^2=root81
a=9ft
therefore, the answer is 9ft.
Answer:
7/5
Step-by-step explanation:
rewrite as an equation ..
3 4/5 \ x = 2 5/7
times x to both sides
2 5/7x= 3 4/5
divide 2 5/7 from both sides
x=7/5
Answer:
Step-by-step explanation:
Just multiply the first equation by -1 and then add them together to find x. Should look something like
-2x - y = -7
5x + y = 9
--------------------
3x + 0 = 2
x = 2/3
Now back substitute using either equation to find y. I'll use the first:
2(2/3) + y = 7
4/3 + y = 7
y = 7 - 4/3 = 21/3 - 4/3 = 17/3
Answer:
x=2/3
y=17/3
